Context for the Curious Book Reader

Most developer tooling assumes that communicating with intelligent agent endpoints requires heavy client applications, complex SDK wrappers, or bloated agent frameworks. This practical treatise explores a different path: speaking the Model Context Protocol (MCP) directly from a standard Unix terminal using pure Python and standard HTTP. Through an iterative conversation between human and machine, we unpack how different enterprise endpoints under the same vendor rely on distinct authentication mechanics—proving that security schemes belong to individual servers rather than corporate brands. It is an important look at maintaining simplicity and determinism in your local tool loop when interacting with diverse APIs in the Age of AI.

TL;DR: Terminal-Native MCP Without the Bloat

Most AI tooling assumes Model Context Protocol (MCP) servers must run behind heavyweight desktop apps, SDK wrappers, or complex agent frameworks. This walkthrough proves you can speak MCP directly from a standard Unix terminal using pure Python and standard HTTP.

Along the way, connecting to two enterprise MCP endpoints from the same vendor revealed a fundamental reality: authentication schemes belong to individual servers, not vendor brands.

Server 1 (OAuth 2.1 PKCE): Discovers endpoints automatically via RFC 8414, handles browser login once, and relies on an in-place mcp_warm.py --refresh command to keep 300-second access tokens alive without re-opening a browser.
Server 2 (Static Pre-Shared Token): Bypasses OAuth entirely, speaking direct Streamable HTTP using standard Authorization: Token headers without requiring an npx bridge.
Security & Hygiene: Credentials derive paths automatically from server URLs (~/.config/pipulate/mcp/<host>.json) so tokens never leak across endpoints, and all interactions generate clean Flight Data Recorder (FDR) receipts with zero token exposure.

MikeLev.in: Okay at its heart what we’re really doing here is making things easier, although it doesn’t always feel that way. I can demonstrate MCP login using OAuth from the terminal like this. This is me doing it twice:

(nix) pipulate $ python scripts/connectors/mcp_warm.py 
# gate2 GREEN via RFC 8414: https://app.botify.com/.well-known/oauth-authorization-server
# gate3 GREEN: client_id minted via RFC 7591 dynamic registration
# gate4: opening browser (redirect catch on http://127.0.0.1:44171/callback)
#        if no browser appears, open this URL yourself:
https://app.botify.com/oauth/authorize?response_type=code&client_id=<redacted:40>&redirect_uri=http%3A%2F%2F127.0.0.1%3A44171%2Fcallback&state=<redacted:22>&code_challenge=<redacted:43>&code_challenge_method=S256&resource=https%3A%2F%2Fmcp.botify.com%2F&scope=mcp_read_write
Opening in existing browser session.
# gate5 GREEN: token written to /home/mike/.config/pipulate/mcp_botify_token.json (0600)
#   scope: mcp_read_write | expires_in: 300
# Next: python scripts/connectors/mcp.py https://mcp.botify.com --check
(nix) pipulate $ python scripts/connectors/mcp_warm.py 
# gate2 GREEN via RFC 8414: https://app.botify.com/.well-known/oauth-authorization-server
# gate3 GREEN: client_id minted via RFC 7591 dynamic registration
# gate4: opening browser (redirect catch on http://127.0.0.1:36851/callback)
#        if no browser appears, open this URL yourself:
https://app.botify.com/oauth/authorize?response_type=code&client_id=<redacted:40>&redirect_uri=http%3A%2F%2F127.0.0.1%3A36851%2Fcallback&state=<redacted:22>&code_challenge=<redacted:43>&code_challenge_method=S256&resource=https%3A%2F%2Fmcp.botify.com%2F&scope=mcp_read_write
Opening in existing browser session.
# gate5 GREEN: token written to /home/mike/.config/pipulate/mcp_botify_token.json (0600)
#   scope: mcp_read_write | expires_in: 300
# Next: python scripts/connectors/mcp.py https://mcp.botify.com --check
(nix) pipulate $

And that pops open the browser and allows me to authenticate and then returns to the terminal. It’s a very short authentication; it expires quickly but it gets the point across that we can do MCP from the terminal; or at least it starts to. I want to make sure I understand my own ability here to connect to MCP servers and use them directly from terminal here. Help me understand.

Opus 5 Extra: Context verified.

One live signal first: the Manifest’s render canary reached me wrapped in markdown link syntax, which is the decisive reading. Nothing in this turn’s patch car quotes a bare www-prefixed token, so nothing here is at risk, but treat any such token elsewhere in this payload as suspect.

What you actually just did

Your receipt maps one-to-one onto mcp_warm.py’s named gates, and reading it that way is the whole answer.

gate2 GREEN via RFC 8414 means the discovery chain completed. Botify’s MCP resource at mcp.botify.com published an RFC 9728 document naming app.botify.com as its authorization server, and that server published an RFC 8414 document naming its authorize and token endpoints. You did not configure either URL. Both were discovered.

gate3 GREEN: client_id minted via RFC 7591 dynamic registration means you had no MCP_OAUTH_CLIENT_ID set, so the warmer registered a brand new OAuth client with Botify on the spot, POSTing token_endpoint_auth_method: none and the loopback redirect URI it was about to listen on.

gate4 bound a one-shot HTTP server on 127.0.0.1, opened the browser with a PKCE S256 challenge, an anti-CSRF state, and an RFC 8707 resource indicator pinning the token to mcp.botify.com. Your browser session authenticated you; the AS redirected back to the loopback catcher with a code; the catcher checked state before touching it.

gate5 exchanged the code plus the PKCE verifier for a bearer, and wrote it to ~/.config/pipulate/mcp_botify_token.json at mode 0600.

That is a complete, standards-compliant OAuth 2.1 public-client flow, run from a terminal, with no vendor SDK and no AI in the loop. The answer to “can I do MCP from the terminal” is: you already are.

Two things in your own receipt worth noticing

Gate 1 never printed. discover() calls fetch_json(..., "gate1") and that function prints nothing on success. RFC 9728 discovery passed silently, and only its failure would have spoken. It fails loud, so this is not the silent-pass problem in full, but it is the same shape: you have five gates and four receipts.

The redirect port differed between runs (44171, then 36851), and gate3 fired both times. Those two facts interlock. MCP_OAUTH_REDIRECT_PORT is unset, so the catcher binds port 0 and takes whatever the kernel gives it. Because the port is ephemeral, the registered client’s redirect_uris is only valid for that one run, which is why gate3 has no reuse path and registers fresh every single time.

Observed from source: a registration request goes out on every warm that lacks MCP_OAUTH_CLIENT_ID. Inferred, not observed: whether Botify’s AS mints a distinct client each time or dedupes. Your receipt cannot settle it, because the scrubber masks both client IDs to <redacted:40> and length is all that survives. Either way you are accumulating registrations on a vendor’s side as a side effect of demoing your own tool. The fix already exists in the code’s own vocabulary: pin MCP_OAUTH_REDIRECT_PORT, pin MCP_OAUTH_CLIENT_ID, and gate3 stops registering. That is a small future ride, not this one.

Where the credential lives, and what finds it

mcp.py’s resolve_token() walks a ladder, first hit wins:

--token-env NAME, if you passed one
MCP_BEARER_TOKEN
MCP_TOKEN_FILE
BOTIFY_TOKEN_FILE
~/.config/pipulate/mcp_botify_token.json — the default, which is exactly where the warmer writes
BOTIFY_API_TOKEN

Rungs 2 through 4 are dual-purpose: if the env var’s value is a path to a real file, the client JSON-parses it and pulls access_token. Rung 6 is the trap that produced the 2026-07-29 RED. A Botify API token is a different credential class from an OAuth bearer scoped mcp_read_write, and mcp.botify.com answers the wrong class with HTTP 401 at initialize. That is why the warmer exists at all.

Rung 5 also prints a clock note to stderr before returning, so an expired token says so up front instead of arriving disguised as a 401.

The 300-second problem, and the two ways past it

expires_in: 300. Five minutes. That is short enough that it cannot survive the human loop: warm in the browser, read the output, decide what to type, run the check, and you are often already dead. This is banked in the constitution as the reason mcp.py --check is structurally incapable of printing GREEN from a compile lane.

Two ways through:

Chain them. Put the refresh and the call in one command so no human decision sits between them.

Refresh instead of re-warm. mcp_warm.py --refresh spends the stored refresh_token, opens no browser, requires no TTY, and rewrites the token file in place. It is rotation-safe: it keeps the existing refresh token unless the AS hands back a new one. This is the rung that makes MCP usable as a terminal habit rather than a ceremony.

What the client can do today

Four modes, all through one command:

mcp                                        identity walk, opens no socket
mcp <server> --check                       envelope health, exit code is the answer
mcp <server>                               initialize → tools/list
mcp <server> <tool> '<json-args>'          initialize → tools/call

--check is the useful one. It prints protocol=, session=yes|no, tools=N, and auth= on success, and on failure it names the gate: gate1 no token, gate2 the handshake, gate3 the tool listing. The exit code carries the verdict so nothing has to parse the text.

Against Botify, the envelope is witnessed rather than assumed. The protocol string 2025-06-18 came back negotiated verbatim, tools/list returned 38 tools and 56,239 bytes, and every exchange reported session_id_returned: null — this vendor declines the optional Mcp-Session-Id header entirely. Three exchanges ride a successful check, not two: notifications/initialized gets its own record at HTTP 202 with zero bytes.

What it records, and the one thing it doesn’t

Every exchange lands in browser_cache/mcp/<host>/<utc>__<verb>.json under frame mcp-receipt-v1: server, verb, tool, arguments byte-for-byte from argv, declared determinism class, the env var name the credential came from, and per exchange the HTTP status, full response headers, elapsed time, session ids both directions, plus body_sha256 and body_bytes. The token value never touches disk. An atexit hook flushes it, so a RED that dies mid-flight still writes a receipt — the recording exists because of the crash.

The gap: it records the body’s fingerprint, not the body. body_sha256 proves a later file is the same payload; it cannot reconstruct a payload nobody kept. Meanwhile stdout truncates at --max-bytes (default 4000). For a tool returning a few kilobytes of JSON that is fine. For a renderer returning a hydrated DOM plus a network log, the box is currently recording the manifest and losing the cargo.

The edges — what to expect to hit

Bearer only. make_client() hardcodes Authorization: Bearer. A server whose docs say Authorization: Token will 401 with a perfectly valid credential, and the failure looks like a bad token rather than a wrong grammar.

Streamable HTTP only. There is no stdio transport. Local MCP servers that speak over a subprocess pipe are not reachable by this client at all.

Last SSE object wins. parse_body() collects every data: frame and returns only the last one. A server that streams progress — job accepted, browser started, artifact created, final result — has its intermediate frames silently discarded.

No player. The recorder writes receipts; nothing reads one back, re-issues the call from args_raw, and adjudicates the body hash by declared class. foo_replay.py replays cartridges to models, which is a different machine. “Send me the artifact and I’ll reproduce it” is currently a posture, not a command.

Not on the wallet board. There is no mcp slot in connectors.json, so warm mcp refuses and the red/green board is blind to this credential. That is not merely an omission: the wallet’s staleness model is --stale-days with a 7-day default, and a 300-second token would read filled for a week while being dead for 99.9% of it. Enrolling it naively would make the board lie. The honest shape is a slot marked "enrolled": false whose warm fixer runs mcp_warm.py --refresh.

No short word for the warmer. mcp is aliased to the client. The warmer has no alias and no wallet slot, so the credential half of the pair is reachable only by full path. That asymmetry is why you typed python scripts/connectors/mcp_warm.py twice.

Discovering the Two Auth Realities

1. PROBES

Read-only. The second and third are guarded so an empty receipt directory prints a token instead of hanging on stdin. The FDR projection deliberately omits response_headers: a remote service can put cookies or signed locations there, and that block has no business entering a cloud-bound payload.

jq 'keys, {scope, expires_in, obtained_at, token_type, has_refresh: has("refresh_token"), client_id_len: (.client_id|length)}' ~/.config/pipulate/mcp_botify_token.json
f=$(ls -t browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | head -1); if [ -n "$f" ]; then jq '{frame, server, verb, tool, dclass, auth_env, exchanges: [.exchanges[] | {jsonrpc_method, http_status, session_id_sent, session_id_returned, body_bytes, elapsed_seconds}]}' "$f"; else echo "no_mcp_receipts"; fi
n=$(ls browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | wc -l); echo "mcp_receipts=$n"; ls -t browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | head -5 | sed 's#.*/##'

Probe 1 answers whether the token file carries a refresh_token at all, which decides whether the no-browser lane is available to you or whether every use costs a browser. Probe 2 is the envelope: it should show three exchanges on a check, HTTP 200/202/200, and null session ids both directions. Probe 3 counts flights, which tells you how much history the box has already banked without your asking.

2. NEXT CONTEXT

The current payload is 447k tokens and most of it is the walk lane and four articles, none of which an MCP turn needs. Trim adhoc.txt to this:

! jq 'keys, {scope, expires_in, obtained_at, token_type, has_refresh: has("refresh_token"), client_id_len: (.client_id|length)}' ~/.config/pipulate/mcp_botify_token.json
! f=$(ls -t browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | head -1); if [ -n "$f" ]; then jq '{frame, server, verb, tool, dclass, auth_env, exchanges: [.exchanges[] | {jsonrpc_method, http_status, session_id_sent, session_id_returned, body_bytes, elapsed_seconds}]}' "$f"; else echo "no_mcp_receipts"; fi
! n=$(ls browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | wc -l); echo "mcp_receipts=$n"; ls -t browser_cache/mcp/mcp.botify.com/*.json 2>/dev/null | head -5 | sed 's#.*/##'
scripts/connectors/mcp.py
scripts/connectors/mcp_warm.py
scripts/connectors/wallet.py
scripts/connectors/README.md
flake.nix

3. PATCHES

No repo patches required. Nothing here is a defect; it is a map.

One actuator car, and it is mutating rather than a probe, because --refresh rewrites the token file. Run it in your terminal, not as an echoed line:

python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com --check

If that prints mcp GREEN, the no-browser lane is live and you have a working terminal MCP client with a five-minute refill. If gate6 refuses, the token file carries no refresh_token and every use costs a browser warm — which changes the ergonomics enough that pinning the client id and redirect port stops being tidiness and becomes the next ride.

Then, to see what is actually on the other end:

python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com -n 50

Ignition: none required. Every probe and actuator invokes the patched-or-not file directly at call time.

4. PROMPT

Terminal MCP is mapped. Three receipts in this compile's LIVE COMMAND RECEIPTS,
plus my hand-run of the refresh+check chain pasted below.

Read the receipts first and rule on two things:

1. Does the token file carry a refresh_token? If yes, the no-browser lane is
   live and mcp_warm.py --refresh is the daily driver. If no, say so and stop
   treating --refresh as available.

2. From the FDR projection: how many exchanges, what statuses, and are both
   session id fields null? If a session id appeared, the envelope changed and
   the constitution's "session=no for this vendor" line is stale.

Then pick ONE of these as the next ride and tell me why it beats the others.
Do not start two.

A. THE PLAYER. mcp.py replay <receipt.json> -- re-issue from args_raw, hash the
   body, adjudicate by declared class: D0 identical or fail, D1 identical or
   drift-with-timestamp, D2 refuse to rule and print "new observation at <ts>".
   This is the named debt from the last article and it is what turns "send me
   the artifact" from a posture into a command.

B. THE WALLET SLOT. An mcp slot in connectors.json, "enrolled": false, whose
   warm fixer runs mcp_warm.py --refresh. Names the credential on the board
   without making GOLD unreachable. Note the 300-second-vs-7-day staleness
   mismatch before proposing a kind.

C. THE PINNED CLIENT. MCP_OAUTH_REDIRECT_PORT plus reusing the client_id the
   token file already stores, so gate3 stops POSTing a fresh RFC 7591
   registration on every warm. Cheapest of the three; least visible payoff.

Whichever you pick, name its cheapest falsifying probe before any patch.

5. EXTERNAL DELIVERABLES

None this turn.

MikeLev.in: Right, I need to make MCP usable as a terminal habit. I’ll follow the 5-Car Train but what I think we’re really moving towards here is making the way MCP works here arbitrarily many MCP servers elegantly without creating a tangle of stuff nightmare. We want to somehow maintain the simplicity of the system but allow maybe a JSON file to register the various MCP servers. Already Botify has 2 different MCP servers I need to interact with this way and this is only the first of the two.

3: Patches: None

4: Prompt: Terminal MCP is mapped. Three receipts in this compile’s LIVE COMMAND RECEIPTS, plus my hand-run of the refresh+check chain pasted below.

Read the receipts first and rule on two things:

Does the token file carry a refresh_token? If yes, the no-browser lane is live and mcp_warm.py –refresh is the daily driver. If no, say so and stop treating –refresh as available.
From the FDR projection: how many exchanges, what statuses, and are both session id fields null? If a session id appeared, the envelope changed and the constitution’s “session=no for this vendor” line is stale.

Then pick ONE of these as the next ride and tell me why it beats the others. Do not start two.

A. THE PLAYER. mcp.py replay -- re-issue from args_raw, hash the body, adjudicate by declared class: D0 identical or fail, D1 identical or drift-with-timestamp, D2 refuse to rule and print "new observation at ". This is the named debt from the last article and it is what turns "send me the artifact" from a posture into a command.

B. THE WALLET SLOT. An mcp slot in connectors.json, “enrolled”: false, whose warm fixer runs mcp_warm.py –refresh. Names the credential on the board without making GOLD unreachable. Note the 300-second-vs-7-day staleness mismatch before proposing a kind.

C. THE PINNED CLIENT. MCP_OAUTH_REDIRECT_PORT plus reusing the client_id the token file already stores, so gate3 stops POSTing a fresh RFC 7591 registration on every warm. Cheapest of the three; least visible payoff.

Whichever you pick, name its cheapest falsifying probe before any patch.

5: Deliverables: Deeper understanding of how MCP works here. Give some thought to the supporting multiple MCP servers thing.

Opus 5 Extra: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax, which is the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing in my probes or caboose carries one (every URL I reference is scheme-bearing), so nothing here is at risk, but treat the payload accordingly.

Ruling 1 — the refresh token

Item	Colour	Receipt	Lane
`refresh_token` present	🟢	`has_refresh: true`, key list includes `refresh_token`	compile (LIVE)
Refresh actually spends it	🟢	`gate6 GREEN: refreshed in place`, `expires_in: 300`	operator
Refresh survives the spend	🟢	`has_refresh: true` still, after the refresh	compile (LIVE)
Chain reaches GREEN	🟢	`mcp GREEN ... protocol=2025-06-18 session=no tools=42`	operator

The no-browser lane is live. mcp_warm.py --refresh is the daily driver, and it is the only shape that survives the 300-second life, because a browser warm plus a human decision plus a check does not fit inside five minutes.

The straddle moved cleanly, which is worth naming because it is what makes this a reading rather than a snapshot. Your BEFORE tap read obtained_at: 20:11:17 and mcp_receipts=14. The compile’s AFTER tap reads obtained_at: 20:33:24 and mcp_receipts=15, and the newest receipt is 20260829T203325770038Z__check.json — the exact flight your chained command produced. Two taps, one command, and the displacement is the evidence.

The rotation question stays open. The refresh token survived both refreshes, so either the AS does not rotate or the rotation-safe branch in refresh() stored a replacement. The receipt cannot distinguish those without quoting a value, which it never will.

Ruling 2 — the envelope

Three exchanges, not two:

Exchange	Status	session sent	session returned	bytes
`initialize`	200	null	null	328
`notifications/initialized`	202	null	null	0
`tools/list`	200	null	null	65,771

All four session fields null. session=no for this vendor holds, and it now holds across two dated flights 23 days apart (2026-08-06 and 2026-08-29). The constitution’s line is not stale. Mcp-Session-Id remains witnessed only by the fault harness, which shares mcp.py’s spec reading and is therefore still the tautology the rule already flagged.

The finding you did not ask for

The body grew. On 2026-08-06, tools/list returned 38 tools in 56,239 bytes. On 2026-08-29, it returned 42 tools in 65,771 bytes. Both numbers are receipted: the byte counts from the FDR (your BEFORE tap reads the Aug 6 receipt, the compile reads the Aug 29 one), the tool counts from the constitution’s Aug 6 banking and your GREEN check line today.

That is a real vendor-side change caught by the recorder without anyone looking for it. It also settles the determinism class: tools/list against this server is D1, not D0, and drift is the ordinary case rather than the exception.

It has a direct consequence for your option A, which I will come to.

The pick: C, widened

C, and the reason is not that it is cheapest. It is that C is the only one of the three that touches the OAuth identity plumbing your two-server problem actually needs. A and B are both blocked, and each is blocked by something checkable in this payload rather than by taste.

A is blocked by a missing capability. The FDR records body_sha256 and body_bytes, never the body. A player built on that can compare hashes and nothing else. Apply it to the 56,239 → 65,771 pair and it prints “D1 DRIFT” and stops — correct, useless, and unable to say that four tools were added. Given that drift is now the observed common case, shipping the adjudicator before the body store means shipping a verdict machine that returns a boolean on exactly the case that occurs. A needs body persistence first, and nobody has scoped what that costs (a 65KB body per flight, times 15 flights and counting, in a gitignored directory). A is deferred with a named prerequisite, not rejected.

B is blocked by wallet dispatch. Three separate walls, all readable in wallet.py:

check_slot shells out to <slot_name>.py --check. A slot named mcp runs mcp.py --check with no server positional. main() tests if args.server is None before the --check branch, so that call takes the identity walk, opens no socket, and returns normally. Exit 0. The live board would print a green row for a call that never left the machine, and the evidence text would be the last line of the identity banner. That is a false green in the one lane whose entire job is refusing false greens.
A slot named anything else (botify_mcp) routes to a module that does not exist, reads UNCHECKED, and blocks GOLD permanently.
login() loads <slot_name>.py and demands a callable get_service. mcp.py exposes identity, check, list_tools, call_tool. No get_service. So warm mcp for an oauth_token_file slot dies at that check, and _warm_oauth routes straight into it.

Plus the staleness mismatch you already flagged: --stale-days defaults to 7 and is mtime-based, so a 300-second token reads filled for a week while being dead 99.9% of that week. B looks like a config edit and is three code changes.

C is the half of multi-server that is already named. The RFC 8707 resource indicator in mcp_warm.py pins each token to one server, so two Botify MCP servers need two tokens and the tokens are not interchangeable. The client_id and the redirect port, by contrast, belong to the authorization server, not the resource — and both your servers sit under app.botify.com. Pin those once and you register once, then mint N resource-scoped tokens against the same client. That is exactly what makes N servers cheap instead of N registrations per warm.

C as stated is the smaller half

The bigger half is in the same two files and the same beat, so it is one ride and not two.

Right now the credential path is a function of nothing:

mcp_warm.py:  DEFAULT_OUT = ~/.config/pipulate/mcp_botify_token.json
mcp.py:       default_token_file = ~/.config/pipulate/mcp_botify_token.json

resolve_token() never receives the server argument. So mcp.py https://mcp.other.example --check resolves the Botify bearer and sends it to a third party. Guaranteed 401 in the ordinary case, and a credential crossing a boundary it was never scoped for in the unusual one. And a second Botify server warmed with the default --out clobbers the first one’s token silently.

This is the DERIVED-PATH RULE, aimed at credentials: the write target should be a pure function of an identity value the tool reads and cannot author. Make it ~/.config/pipulate/mcp/<host>.json and collision becomes unrepresentable, N servers cost zero config lines, and the token a client sends is structurally the token that server minted.

The pattern is already in this repo twice. The FDR writes to browser_cache/mcp/<host>/<utc>__<verb>.json — derived from the host, right there in the same file. And prompt_foo.resolve_prompt_foo_cache keys on netloc/path_slug. One half of mcp.py already runs the pattern the other half needs.

On registering many servers

You said “maybe a JSON file to register the various MCP servers.” I would build the derivation first and the registry second, and I think the registry then turns out to be much smaller than it looks.

Derivation first, because it cannot be wrong. If the token path is f(server), then adding a server is: type its URL once at mcp_warm.py, and from then on mcp.py <url> finds its own credential. No mapping table to keep in sync, no naming decision, no drift between what the warmer wrote and what the client reads. If you build the registry first, you get a mapping table nobody validates on top of a token path that is still a choice, and the choice is where the collision lives.

Then the registry holds only what cannot be derived. Something like ~/.config/pipulate/mcp_servers.json:

{
  "botify": { "url": "https://mcp.botify.com/", "scope": "mcp_read_write" },
  "botify-two": { "url": "https://<second-host>/", "scope": "..." }
}

A nickname, a scope override, a pinned client_id, a pinned redirect port, an enrollment flag. Names and paths, never values — the same discipline connectors.json already runs. Then mcp botify --check resolves nickname → URL → derived token path, and a full URL still works with no registry at all. Registry absent is a start state, not a fault, which is the lesson load_wallet’s cold-start card already learned.

Do not put MCP servers in connectors.json. The wallet’s five auth kinds do not fit an endpoint-plus-credential-plus-discovery-chain, and its dispatch is name-based in a way that breaks (see B above). Adding a sixth kind means touching classify_slot, _next_hint, _warm_oauth, check_slot, and the staleness model. That is the tangle you said you want to avoid. Two files with clean edges beat one file with a sixth special case.

Deriving Credential Paths for Zero Collision

One open question I cannot answer from here. Host-keying works only if your two Botify servers differ by host. If they differ by path on the same host, the key has to be host-plus-path-slug, which is exactly what resolve_prompt_foo_cache already does. That decision belongs in the patch turn and needs one fact from you.

On the habit word. Do not make resolve_token auto-refresh. The constitution is right that a resolver which silently re-mints is a resolver whose failures stop being visible, and _expiry_note printing ~299s left of a 300s life in your chain output is that separation paying off. The habit is a chained alias in the operator lane only — refresh, then act — and it must never be echoed as a ! probe, because a refresh mutates. That is a small car for the same ride as the alias work, not a separate one.

1. PROBES

Read-only, bounded, and none of them sends a packet to a third party. Probe 2 in particular deliberately reads source rather than testing the cross-server send, because a probe that demonstrates a credential leak by performing one is the instrument becoming the harm.

out=$(python scripts/connectors/mcp.py --check 2>&1); echo "bare_check_exit=$?"; printf '%s\n' "$out" | head -3
rg -n 'mcp_botify_token|DEFAULT_OUT|DEFAULT_RESOURCE|default_token_file' scripts/connectors/mcp.py scripts/connectors/mcp_warm.py
rg -l 'def get_service' scripts/connectors/; rg -c 'def get_service' scripts/connectors/mcp.py; echo "mcp_get_service_exit=$?"
n=$(ls -d browser_cache/mcp/*/ 2>/dev/null | wc -l); echo "mcp_hosts=$n"; ls -d browser_cache/mcp/*/ 2>/dev/null | sed 's#.*/mcp/##;s#/$##'

Probe 1 falsifies my central claim about option B. If bare_check_exit=0 and the head shows the identity banner, a wallet slot named mcp would print a false green and B is blocked as stated. If it exits nonzero or shows a RED gate1 line, my reading of the control flow is wrong and B gets cheaper.

Probe 2 is the whole multi-server indictment in one bounded reading: every place the token path and the resource are hardcoded, across both files. Expect roughly nine lines. If any of them already takes the server into account, the derivation ride is smaller than I think.

Probe 3 confirms the get_service wall. The -l listing shows which connectors the wallet’s login path can actually reuse; the -c plus exit code says whether mcp.py is one of them. Exit 1 with empty output is the confirming reading, not a failure.

Probe 4 answers whether the second server has ever been touched by this client. One host means the FDR has only ever seen Botify’s first server, and the derived-path change is a pure greenfield addition. Two or more means there is existing state to migrate.

2. NEXT CONTEXT

The current payload is 267k tokens and most of it is the rolling pin and the constitution. A patch turn on two small connector files does not need the corpus index. Trim adhoc.txt to this:

! out=$(python scripts/connectors/mcp.py --check 2>&1); echo "bare_check_exit=$?"; printf '%s\n' "$out" | head -3
! rg -n 'mcp_botify_token|DEFAULT_OUT|DEFAULT_RESOURCE|default_token_file' scripts/connectors/mcp.py scripts/connectors/mcp_warm.py
! rg -l 'def get_service' scripts/connectors/; rg -c 'def get_service' scripts/connectors/mcp.py; echo "mcp_get_service_exit=$?"
! n=$(ls -d browser_cache/mcp/*/ 2>/dev/null | wc -l); echo "mcp_hosts=$n"; ls -d browser_cache/mcp/*/ 2>/dev/null | sed 's#.*/mcp/##;s#/$##'
scripts/connectors/mcp.py
scripts/connectors/mcp_warm.py
scripts/connectors/README.md
flake.nix
foo_files.py

Drop the rolling pin and GLOSSARY.md for this one. Drop wallet.py too — the ruling on B is banked and the patch turn does not touch it.

3. PATCHES

No repo patches required. You asked for the cheapest falsifying probe before any patch, and that is the correct order here. Two of my four claims are inferences from control flow rather than observations, and the credential-path change carries a migration question (what happens to the working token already sitting at the old path) that I should not answer blind.

No ignition required. Every probe invokes its target file directly at call time.

4. PROMPT

Probes are back for the MCP multi-server ride. Read the LIVE COMMAND RECEIPTS before ruling on anything, and say which lane each reading came from.

Rule on these four, one line each, and say what each one CHANGES rather than just what it says:

1. bare_check_exit. If the LIVE RECEIPT shows exit 0 and the identity banner, option B (the wallet slot) stays blocked as diagnosed and needs code in wallet.py or mcp.py before any connectors.json edit. If it shows anything else, say what it shows and re-open B.
2. The hardcoded-path listing. Name every line where the token path or the resource is fixed independent of the server argument. If any line already derives from the server, say so — that shrinks the ride.
3. mcp_get_service_exit and the -l listing. Confirm or falsify that mcp.py cannot be driven by wallet.py's login path.
4. mcp_hosts. One host means greenfield. More than one means there is existing FDR state under a second host, and I want to know which.

Then answer the one thing the receipts cannot tell you, because I have not told you yet: my second Botify MCP server. I will paste its URL with this prompt. Say whether it differs from mcp.botify.com by HOST or by PATH, because that decides the derivation key — netloc alone if host, netloc plus a path slug (the shape resolve_prompt_foo_cache already uses) if path.

Then emit the ride, as cars, in this order, and stop if a probe falsified the premise of any car rather than patching around it:

CAR 1 — DERIVED CREDENTIAL PATH. mcp_warm.py writes to a path computed from the resource; mcp.py resolves the same path computed from its server argument. One function, defined once, used by both. Name what happens to the existing mcp_botify_token.json: migrate it, read it as a fallback, or leave it and let the next warm write the new location. I want the migration named, not implied.

CAR 2 — PINNED CLIENT. MCP_OAUTH_REDIRECT_PORT plus reuse of the client_id the token file already stores, so gate3 stops POSTing a fresh RFC 7591 registration. Say explicitly whether a client_id minted for one resource can mint a token for a second resource under the same authorization server, and label that answer OBSERVED or INFERRED. If it is inferred, name the probe that would settle it before we rely on it.

CAR 3 — README. The connector contract gains the credential-path convention. One paragraph, in the same voice as the existing auth-kinds paragraph.

Do NOT build the registry file this turn. Derivation first; the nickname table is worth nothing until the path is a function of the server.

Do NOT touch wallet.py this turn regardless of what probe 1 says.

For each car, name the ignition or state "no ignition required", and give me the straddle probe that will read differently after the car lands than before it.

5. EXTERNAL DELIVERABLES

None this turn.

3: Patches: None

4: Prompt: Probes are back for the MCP multi-server ride. Read the LIVE COMMAND RECEIPTS before ruling on anything, and say which lane each reading came from.

Rule on these four, one line each, and say what each one CHANGES rather than just what it says:

bare_check_exit. If the LIVE RECEIPT shows exit 0 and the identity banner, option B (the wallet slot) stays blocked as diagnosed and needs code in wallet.py or mcp.py before any connectors.json edit. If it shows anything else, say what it shows and re-open B.
The hardcoded-path listing. Name every line where the token path or the resource is fixed independent of the server argument. If any line already derives from the server, say so — that shrinks the ride.
mcp_get_service_exit and the -l listing. Confirm or falsify that mcp.py cannot be driven by wallet.py’s login path.
mcp_hosts. One host means greenfield. More than one means there is existing FDR state under a second host, and I want to know which.

Then answer the one thing the receipts cannot tell you, because I have not told you yet: my second Botify MCP server. I will paste its URL with this prompt. Say whether it differs from mcp.botify.com by HOST or by PATH, because that decides the derivation key — netloc alone if host, netloc plus a path slug (the shape resolve_prompt_foo_cache already uses) if path.

Then emit the ride, as cars, in this order, and stop if a probe falsified the premise of any car rather than patching around it:

CAR 1 — DERIVED CREDENTIAL PATH. mcp_warm.py writes to a path computed from the resource; mcp.py resolves the same path computed from its server argument. One function, defined once, used by both. Name what happens to the existing mcp_botify_token.json: migrate it, read it as a fallback, or leave it and let the next warm write the new location. I want the migration named, not implied.

CAR 2 — PINNED CLIENT. MCP_OAUTH_REDIRECT_PORT plus reuse of the client_id the token file already stores, so gate3 stops POSTing a fresh RFC 7591 registration. Say explicitly whether a client_id minted for one resource can mint a token for a second resource under the same authorization server, and label that answer OBSERVED or INFERRED. If it is inferred, name the probe that would settle it before we rely on it.

CAR 3 — README. The connector contract gains the credential-path convention. One paragraph, in the same voice as the existing auth-kinds paragraph.

Do NOT build the registry file this turn. Derivation first; the nickname table is worth nothing until the path is a function of the server.

Do NOT touch wallet.py this turn regardless of what probe 1 says.

For each car, name the ignition or state “no ignition required”, and give me the straddle probe that will read differently after the car lands than before it.

5: Deliverables: None this turn.

Opus 5 Extra: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax — the decisive reading. Every bare www-prefixed token in this payload is suspect. None of my SEARCH blocks or probes carries one (every URL I quote is scheme-bearing, which is the one observed suppressor), so nothing here is at risk.

The four rulings

1. bare_check_exit=0, identity banner in both lanes. Operator hand-run showed EXPIRED 206s ago; the LIVE RECEIPT shows EXPIRED 316s ago — two taps, same verdict, and the drift is just elapsed clock. CHANGES: option B is confirmed blocked, not merely suspected. check_slot shelling mcp.py --check with no server takes the identity walk, opens no socket, and exits 0, so the live board would print a green row for a call that never left the machine. B now needs code before any connectors.json edit. Not touched this turn, per your instruction.

2. Thirteen hardcoded lines, and one of them already does the right thing. mcp_warm.py 8, 55, 56, 250–251, 252–253 and mcp.py 206, 207, 209, 215, 254 are all fixed independent of the server. Line 202 is the exception: resource = record.get("resource") or DEFAULT_RESOURCE reads the resource out of the token file, so the refresh path is already resource-aware given the right file. CHANGES: CAR 1 shrinks — refresh() needs a path derivation, not resource logic. Second finding: --out already exists (line 252), so manual multi-server is possible today via --out plus MCP_TOKEN_FILE. The capability is there; only the derivation is missing.

3. mcp_get_service_exit=1, listing shows gsc/gmail/sheets only. Confirmed: mcp.py cannot be driven by wallet.py’s login path. CHANGES: B needs a third code change, not two. (Both lanes agree on the set; the compile receipt orders it gmail/gsc/sheets and your hand-run gsc/gmail/sheets — rg traversal order, not a discrepancy.)

4. mcp_hosts=1, mcp.botify.com. Greenfield. CHANGES: there is exactly one credential and one host of FDR state, so CAR 1’s migration story is a one-file question rather than a sweep.

The fact that did not arrive

You wrote “I will paste its URL with this prompt.” It is not in the payload. I am not going to infer a hostname.

It does not block CAR 1, and that is worth stating rather than working around: the derivation key I am proposing is netloc plus an optional quoted path slug, which is the shape resolve_prompt_foo_cache already runs. When the path is / it collapses to the bare host, so https://mcp.botify.com/ → mcp.botify.com.json whether or not server two turns out to differ by path. The HOST-vs-PATH question changes the filename you will see, never the mechanism. One of the probes below prints both shapes so the answer arrives as a receipt instead of a decision.

CAR 1 — Derived credential path

The duplication decision, named so you can veto it before running app. You asked for “one function, defined once, used by both.” The house law says the opposite: the connector contract makes each file self-contained with no shared imports, and walk_cartridge.py already duplicates foo_cartridge’s primitives for exactly this reason. A shared import would make mcp.py depend on mcp_warm.py and spend the single-file property.

I duplicated. The risk that creates — the two copies drifting, which fails silently as a credential written where nothing reads it — is handled by making the straddle probe compare their output rather than trusting them. If you want one definition anyway, veto this car and I will re-emit with an import.

The migration, named not implied: read-as-fallback, write-in-place, no move. A read path that relocates a credential is a mutation wearing a resolver’s label — the same objection the constitution already makes to a resolver that silently re-mints. So resolve_token checks derived first and falls back to mcp_botify_token.json with a loud stderr note; refresh finds whichever file exists and rewrites that one in place, which keeps your daily driver unbroken through the transition; only a full browser warm writes the derived location. The fallback branch is self-clearing. After your first browser warm both files will exist and the legacy one becomes dead weight — delete it by hand once you see a green check resolving the derived path.

Ignition: none required. Every probe imports or invokes the patched file at call time.

Straddle: probe 1 below reads an AttributeError tail before this car and two identical derived paths plus a path-slug example after it. Probe 2’s identity output gains a # creds section.

CAR 2 — Pinned client: HELD, with the settling actuator named

Half of this car is already shipped and unused. MCP_OAUTH_REDIRECT_PORT is read at line ~272 of mcp_warm.py today: set it and the loopback binds a fixed port instead of an ephemeral one. That needs no code, only an export.

Whether one client_id can mint tokens for two resources under one AS: INFERRED. No receipt exists, and the inference cuts both ways. RFC 7591 registers a client, RFC 8707 scopes a token, so in principle the client is portable — but this code’s registration POST sends no resource at all, so nothing has ever told Botify’s AS what the client is for, and nothing has ever asked it for a second resource. The scope may also differ per server.

The settling move is an actuator, not a probe (it opens a browser and writes a file), so it does not belong in section 1:

export MCP_OAUTH_REDIRECT_PORT=44171
MCP_OAUTH_CLIENT_ID="$(jq -r .client_id ~/.config/pipulate/mcp_botify_token.json)" \
  python scripts/connectors/mcp_warm.py <SECOND_SERVER_URL>

Gate3 printing client_id from $MCP_OAUTH_CLIENT_ID followed by a gate5 GREEN is the OBSERVED answer. A gate4 authorization error naming an invalid client or redirect URI is the falsification, and it is a clean one — nothing is written on that path. Until that runs, pinning the client_id in code would mean the second warm can fail in a way that looks like a bug in our code rather than a policy on theirs.

CAR 3 — README

## Current connectors
[[[DIVIDER]]]
Credential paths are DERIVED, never chosen. A connector that talks to more than
one server of the same kind — MCP is the first — computes its token path from
the server URL rather than from a constant, so the credential a client sends is
structurally the credential that server minted. mcp.py and mcp_warm.py each
carry an identical `token_path_for()` mapping a resource URL to
`~/.config/pipulate/mcp/<host>.json`, appending a quoted path slug when the
server lives under a path rather than at a host root. Collision is
unrepresentable, an Nth server costs zero configuration lines, and a bearer
scoped to one resource can never be handed to another. The pre-derivation file
`mcp_botify_token.json` is read as a fallback and is never moved by a read path;
the next browser warm writes the derived location and the fallback stops firing.
Duplicating the derivation rather than sharing it is deliberate — each connector
stays self-contained — so the two copies are compared by probe, not trusted.

Ignition: none required.

On the registry, since you raised it

Build the derivation first and the nickname table second, and the table turns out to be much smaller than it looks. Once the path is f(server), adding a server is: type its URL once at mcp_warm.py, and from then on mcp.py <url> finds its own credential — no mapping to keep in sync, no naming decision, no drift between what the warmer wrote and what the client reads. Build the registry first and you get an unvalidated table sitting on top of a token path that is still a choice, and the choice is where the collision lives.

Then ~/.config/pipulate/mcp_servers.json holds only what cannot be derived: nickname, scope override, pinned client_id, pinned port, enrollment flag. Names and paths, never values. Registry absent stays a valid start state.

And keep MCP out of connectors.json. Its five auth kinds do not fit an endpoint-plus-credential-plus-discovery-chain, and adding a sixth means touching classify_slot, _next_hint, _warm_oauth, check_slot, and the staleness model at once. Two files with clean edges beat one file with a special case.

1. PROBES

.venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp, mcp_warm; print("mcp  root:", mcp.token_path_for("https://mcp.botify.com/")); print("warm root:", mcp_warm.token_path_for("https://mcp.botify.com/")); print("mcp  path:", mcp.token_path_for("https://mcp.botify.com/second/"))' 2>&1 | tail -4
out=$(.venv/bin/python scripts/connectors/mcp.py 2>&1); echo "identity_exit=$?"; printf '%s\n' "$out" | head -14
rg -n 'MCP_OAUTH_REDIRECT_PORT|MCP_OAUTH_CLIENT_ID' scripts/connectors/mcp_warm.py
rg -n '^Credential paths' scripts/connectors/README.md; echo "readme_exit=$?"

Probe 1 is the load-bearing one and it does two jobs at once: it proves the derivation exists and it proves the two duplicated copies agree, which is the only real risk the duplication introduces. It opens no socket and writes no file. Before CAR 1 it ends in an AttributeError tail; after, three paths where the first two are identical and the third shows the path-slug shape — which also answers the HOST-vs-PATH question empirically rather than by assertion.

Probe 2 reads the identity walk, which arms no receipt and therefore writes nothing. Before: a # token line and no # creds. After: a # creds block listing the warmed files with clock notes and no values.

Probe 3 establishes a BEFORE fact rather than straddling anything: it confirms the redirect-port env var already exists in the code, which is why CAR 2’s port half needs no patch.

Probe 4 is CAR 3’s straddle. Exit 1 with no output is the confirming BEFORE reading, not a failure.

2. NEXT CONTEXT

! .venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp, mcp_warm; print("mcp  root:", mcp.token_path_for("https://mcp.botify.com/")); print("warm root:", mcp_warm.token_path_for("https://mcp.botify.com/")); print("mcp  path:", mcp.token_path_for("https://mcp.botify.com/second/"))' 2>&1 | tail -4
! out=$(.venv/bin/python scripts/connectors/mcp.py 2>&1); echo "identity_exit=$?"; printf '%s\n' "$out" | head -14
! rg -n 'MCP_OAUTH_REDIRECT_PORT|MCP_OAUTH_CLIENT_ID' scripts/connectors/mcp_warm.py
! rg -n '^Credential paths' scripts/connectors/README.md; echo "readme_exit=$?"
scripts/connectors/mcp.py
scripts/connectors/mcp_warm.py
scripts/connectors/README.md

Drop the rolling pin, GLOSSARY.md, flake.nix, and foo_files.py for the next turn. Nothing in CAR 2’s settling actuator touches them, and the payload is 262k tokens for a three-file ride.

3. PATCHES

Above: CAR 1 (seventeen blocks across two files), CAR 3 (one block). CAR 2 is held pending the second server URL and the client-portability actuator — no patch.

Choreography: patch, app, d, m per car, then blast.

Ignition: none required for either car. Every probe imports or invokes the patched file at call time.

4. PROMPT

CAR 1 and CAR 3 landed (or did not — read the receipts, not my memory). Four
probes are echoed into this compile; name the LANE for each reading.

Rule first, in one line each:

1. Probe 1's three paths. Do mcp.token_path_for and mcp_warm.token_path_for
   return the IDENTICAL string for the same root URL? If they differ by even a
   character, the duplication has already drifted on its first day and CAR 1
   must be re-emitted with a shared import instead. Also read the third line:
   that is the path-slug shape, and it tells me what a path-differentiated
   second server would be filed as.

2. Probe 2's identity output. Is there a "# creds" block? Does it name
   mcp_botify_token.json as "(pre-derivation)"? If the block is absent, the
   identity patch did not land; say so before ruling on anything else.

3. Probes 3 and 4 as pass/fail, no commentary.

Then two things, in this order.

FIRST, the migration receipt I do not yet have. I will paste a hand-run of:
    python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com --check
Rule on whether the stderr note about the pre-derivation file appeared, and
whether the check still reached GREEN. Both must be true: the note proves the
fallback fired, the GREEN proves the fallback did not break the daily driver.
If the note appeared but the check went RED, say which gate and stop — do not
propose a fix in the same breath as the diagnosis.

SECOND, CAR 2, and only if I paste the second server's URL with this prompt.
If I did not paste it, say so plainly and do not invent one. If I did:
  - Say whether it differs from mcp.botify.com by HOST or by PATH, and name the
    exact filename token_path_for will produce for it.
  - Emit CAR 2 as an ACTUATOR car, not a patch car: the exported
    MCP_OAUTH_REDIRECT_PORT plus the MCP_OAUTH_CLIENT_ID prefix that reuses the
    client_id already sitting in the Botify token file. Name what gate3 should
    print on success and what gate4 should print on the falsification, so I can
    tell a policy refusal from a code bug.
  - Do NOT patch obtain_client_id until that actuator has run. The portability
    of a DCR-minted client across resources is INFERRED and one browser warm
    settles it.

Do NOT build the registry file. Do NOT touch wallet.py. Do NOT delete
mcp_botify_token.json in a patch — that is my hand, after I see a green check
resolving the derived path.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

5. EXTERNAL DELIVERABLES

None this turn.

 semrush — a persistent Chrome profile under data/uc_profiles/<name>, warmed by
 weblogin.py, not a token). Every future connector copies one of these five.
 
+Credential paths are DERIVED, never chosen. A connector that talks to more than
+one server of the same kind — MCP is the first — computes its token path from
+the server URL rather than from a constant, so the credential a client sends is
+structurally the credential that server minted. mcp.py and mcp_warm.py each
+carry an identical `token_path_for()` mapping a resource URL to
+`~/.config/pipulate/mcp/<host>.json`, appending a quoted path slug when the
+server lives under a path rather than at a host root. Collision is
+unrepresentable, an Nth server costs zero configuration lines, and a bearer
+scoped to one resource can never be handed to another. The pre-derivation file
+`mcp_botify_token.json` is read as a fallback and is never moved by a read path;
+the next browser warm writes the derived location and the fallback stops firing.
+Duplicating the derivation rather than sharing it is deliberate — each connector
+stays self-contained — so the two copies are compared by probe, not trusted.

4: Prompt: CAR 1 and CAR 3 landed (or did not — read the receipts, not my memory). Four probes are echoed into this compile; name the LANE for each reading.

Rule first, in one line each:

Probe 1’s three paths. Do mcp.token_path_for and mcp_warm.token_path_for return the IDENTICAL string for the same root URL? If they differ by even a character, the duplication has already drifted on its first day and CAR 1 must be re-emitted with a shared import instead. Also read the third line: that is the path-slug shape, and it tells me what a path-differentiated second server would be filed as.
Probe 2’s identity output. Is there a “# creds” block? Does it name mcp_botify_token.json as “(pre-derivation)”? If the block is absent, the identity patch did not land; say so before ruling on anything else.
Probes 3 and 4 as pass/fail, no commentary.

Then two things, in this order.

FIRST, the migration receipt I do not yet have. I will paste a hand-run of: python scripts/connectors/mcp_warm.py –refresh && python scripts/connectors/mcp.py https://mcp.botify.com –check Rule on whether the stderr note about the pre-derivation file appeared, and whether the check still reached GREEN. Both must be true: the note proves the fallback fired, the GREEN proves the fallback did not break the daily driver. If the note appeared but the check went RED, say which gate and stop — do not propose a fix in the same breath as the diagnosis.

SECOND, CAR 2, and only if I paste the second server’s URL with this prompt. If I did not paste it, say so plainly and do not invent one. If I did:

Say whether it differs from mcp.botify.com by HOST or by PATH, and name the exact filename token_path_for will produce for it.
Emit CAR 2 as an ACTUATOR car, not a patch car: the exported MCP_OAUTH_REDIRECT_PORT plus the MCP_OAUTH_CLIENT_ID prefix that reuses the client_id already sitting in the Botify token file. Name what gate3 should print on success and what gate4 should print on the falsification, so I can tell a policy refusal from a code bug.
Do NOT patch obtain_client_id until that actuator has run. The portability of a DCR-minted client across resources is INFERRED and one browser warm settles it.

Do NOT build the registry file. Do NOT touch wallet.py. Do NOT delete mcp_botify_token.json in a patch — that is my hand, after I see a green check resolving the derived path.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None this turn.

Opus 5 Extra: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax, which is the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing in my patch or probes carries one.

The four rulings

#	Reading	Colour	BEFORE (operator lane)	AFTER (compile lane, LIVE)
1	`token_path_for` agreement	🟢	`AttributeError: module 'mcp' has no attribute 'token_path_for'`	`mcp root:` and `warm root:` return the identical string
2	`# creds` block	🟢	absent; `# token : resolved from mcp_botify_token.json`	present; `mcp_botify_token (pre-derivation)`
3	`MCP_OAUTH_*` in source	🟢 pass	lines 113/115/119/122/274/276	lines 129/131/135/138/302/304
4	README paragraph	🟢 pass	`readme_exit=1`, no output	`readme_exit=0`, line 65

1. Both functions return /home/mike/.config/pipulate/mcp/mcp.botify.com.json, character for character. The duplication has not drifted. The third line reads mcp.botify.com__second.json, so a path-differentiated second server files as <host>__<quoted-path>.json. CHANGES: CAR 1 stands as emitted; no re-emit with a shared import. The duplication is now a witnessed invariant rather than a hoped-for one, and probe 1 stays on the roster permanently as its guard.

2. The # creds block is present and correctly tags the legacy file. CHANGES: the identity patch landed, so the ruling on items 3 and 4 is safe to take. It also gives you an unplanned win: mcp with no arguments is now a credential inventory board, and the (pre-derivation) tag is the signal that tells you when the legacy file is safe to delete by hand.

3. Pass.

4. Pass.

The displacement arithmetic closes exactly

Probe 3 was written as a static existence check and turned into a displacement receipt for free. The gate3 cluster moved +16 (113→129) and the port cluster moved +28 (274→302). Your own diffstat accounts for both: the token_path_for insertion was +15, the TOKEN_DIR/LEGACY split was net +1, giving 16; then the refresh() out_path block was net +11 and the argparse --out change net +1, giving 28. Four unchanged anchors, arithmetic closing from both ends. That is a stronger reading than the extent of the insertions, and I had not predicted it.

The two things that did not arrive

The migration receipt is not in this payload. You wrote “I will paste a hand-run of” the refresh-plus-check chain. It is not there. The refresh+check GREEN that is in the transcript is from two turns ago, before any of this landed — a stale BEFORE wearing an AFTER’s label, and I am not treating it as the migration receipt. Section 3 of this turn ends at git push.

The second server URL is not in this payload either. You said you would paste it. You did not. I am not inventing one, so CAR 2 stays held.

Both are one hand-run away and both are in the train below.

What the receipt caught that nobody was looking for

Probe 2’s BEFORE and AFTER differ in one word, and the AFTER is worse:

BEFORE:  # token    : resolved from mcp_botify_token.json (value never printed)
AFTER:   # token    : env lane resolved from mcp_botify_token.json (value never printed)

Every env var was unset. identity() calls resolve_token() with no server, so server is None, default_token_file is set to LEGACY_TOKEN_FILE, and the file rung fired. The label names a lane that did not run.

That is the ATTRIBUTED-VOICE mechanical test failing on the first line a newcomer reads, and it is self-inflicted: the previous turn’s patch took a correct string and made it wrong while adding the # creds block below it. The BEFORE string was more accurate than the AFTER one.

The lane distinction is worth keeping now that there genuinely are two lanes. resolve_token returns a bare env-var name, or NAME:file.json when an env var pointed at a file, or a bare <stem>.json when the warmed-file rung fired. Only the last has a .json suffix and no colon, so the discrimination is exact rather than heuristic.

One thing that looks like a defect and is not: the clock note appears twice in probe 2’s receipt. One copy is resolve_token’s stderr write, the other is the # creds loop’s stdout. The probe merged 2>&1, which is why they collided. On stdout alone only one appears. Two channels, two audiences, correct as built.

On many servers, since it is the standing thread

The derivation is the elegance you asked for, and it landed. Server N now costs: one browser warm at mcp_warm.py <url>, and from then on mcp <url> --check finds its own credential. Zero configuration lines, no mapping table, no naming decision, and a bearer scoped to one resource is structurally incapable of being handed to another.

What is left for the registry is only what cannot be derived: a nickname so you type mcp botify-two instead of a URL, a scope override, a pinned client id, an enrollment flag. That table is worth building after CAR 2 settles the client-portability question, because a pinned client id is one of its columns and I do not yet know whether one exists.

Still holding: no registry file, no wallet.py, no deletion of the legacy token in a patch.

1. PROBES

.venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp, mcp_warm; r="https://mcp.botify.com/"; print("agree:", mcp.token_path_for(r) == mcp_warm.token_path_for(r)); print("root:", mcp.token_path_for(r).name); print("slug:", mcp.token_path_for("https://mcp.botify.com/second/").name)' 2>&1 | tail -3
.venv/bin/python scripts/connectors/mcp.py 2>/dev/null | rg -n 'token    :|creds    :'

Probe 1 is the permanent drift guard for the duplicated derivation, restated as a boolean so the answer is read rather than eyeballed. It opens no socket and writes no file.

Probe 2 is the straddle for the car below. It reads stdout only on purpose: the discarded stderr carries the clock note, whose seconds value changes every run and would make the receipt non-comparable across taps. The verdict reads nothing on that channel. Before the car it prints env lane; after, file lane.

Note on the retired form: last turn’s head -14 landed on exactly 14 lines of identity() output, so one more print in that function would have silently truncated the receipt with no ellipsis. The rg form above is content-bounded instead of count-bounded and cannot hit that.

Probes 3 and 4 are retired. Both straddled cleanly in both directions, and an instrument that now fires green on every run is noise wearing an instrument’s costume.

2. NEXT CONTEXT

! .venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp, mcp_warm; r="https://mcp.botify.com/"; print("agree:", mcp.token_path_for(r) == mcp_warm.token_path_for(r)); print("root:", mcp.token_path_for(r).name); print("slug:", mcp.token_path_for("https://mcp.botify.com/second/").name)' 2>&1 | tail -3
! .venv/bin/python scripts/connectors/mcp.py 2>/dev/null | rg -n 'token    :|creds    :'
scripts/connectors/mcp.py
scripts/connectors/mcp_warm.py

This payload is 273k tokens for a one-line label edit. The rolling pin (60k), foo_files.py (74k), flake.nix (28k) and GLOSSARY.md (7.5k) are 62% of it and none is touched by anything in this train. Drop all four, plus README.md now that CAR 3 is banked.

3. PATCHES

One car, and it is unrequested — found in probe 2’s own receipt rather than asked for. Veto it freely; the defect is cosmetic in blast radius and precise in kind.

Target: scripts/connectors/mcp.py
[[[SEARCH]]]
    if token:
        print(f"# token    : env lane resolved from {token_name} (value never printed)")
        print("#            resolved is not accepted -- only --check posts")
[[[DIVIDER]]]
    if token:
        # THE LANE IS PART OF THE CLAIM (convicted 2026-08-29 by this walk's own
        # receipt). The prior string said "env lane resolved from
        # mcp_botify_token.json" while every env var was unset and the FILE rung
        # had fired -- a label naming a lane that did not run, which is the
        # ATTRIBUTED-VOICE mechanical test failing on the first line a newcomer
        # reads. It was also a REGRESSION: the string it replaced said only
        # "resolved from", which was correct. resolve_token returns a bare env
        # var NAME, or "NAME:file.json" when an env var pointed at a file, or a
        # bare "<stem>.json" when the warmed-file rung fired; only the last of
        # those carries a .json suffix and no colon, so the discrimination is
        # exact rather than heuristic.
        lane = "file lane" if (":" not in token_name
                               and token_name.endswith(".json")) else "env lane"
        print(f"# token    : {lane} resolved from {token_name} (value never printed)")
        print("#            resolved is not accepted -- only --check posts")
[[[REPLACE]]]

Ignition: none required. Probe 2 invokes the patched file at call time.

CAR 2 remains held pending the second server URL. When you have it, the settling move is an actuator (it opens a browser and writes a file), so it never rides in PROBES:

export MCP_OAUTH_REDIRECT_PORT=44171
MCP_OAUTH_CLIENT_ID="$(jq -r .client_id ~/.config/pipulate/mcp_botify_token.json)" \
  python scripts/connectors/mcp_warm.py <SECOND_SERVER_URL>

# gate3 GREEN: client_id from $MCP_OAUTH_CLIENT_ID followed by a gate5 GREEN is the OBSERVED answer that a DCR-minted client is portable across resources under one authorization server. A gate4 authorization error naming an invalid client or redirect URI is the falsification, and it is clean: nothing is written on that path. Until one of those prints, portability stays INFERRED and obtain_client_id stays unpatched.

The migration receipt is also an actuator, not a probe, because --refresh rewrites the token file:

python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com --check

Predicted, from raw source: two stderr notes, not one. refresh() prints # refreshing the pre-derivation file mcp_botify_token.json IN PLACE, and resolve_token prints # mcp credential: reading the pre-derivation file mcp_botify_token.json; the next browser warm writes /home/mike/.config/pipulate/mcp/mcp.botify.com.json. Then mcp GREEN with auth=mcp_botify_token.json. If you see one note instead of two, one of the two fallback branches did not fire and that is the finding.

Choreography: patch, app, d, m, then blast.

4. PROMPT

The lane-label car landed (or did not — read the receipts, not my memory).
Two probes are echoed into this compile. Name the LANE for each reading.

Rule first, one line each:

1. Probe 1. Does it print "agree: True"? If False, the two copies of
   token_path_for have drifted and everything below stops until that is fixed.
   Also report the "slug:" line unchanged, so the path-differentiated filename
   shape stays on the record.

2. Probe 2. Does the token line say "file lane" or "env lane"? file lane means
   the car landed and the label now names the rung that actually fired. env
   lane means it did not land — say so before ruling on anything else. Confirm
   the "creds" line still shows the (pre-derivation) tag.

Then, in this order, and only for what I actually pasted:

FIRST, the migration receipt. I will paste a hand-run of:
    python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com --check
You predicted TWO stderr notes — one from refresh(), one from resolve_token().
Rule on whether both appeared, and whether the check reached GREEN. Two notes
plus GREEN is the full pass. One note plus GREEN means one fallback branch did
not fire; say which one and stop. Any note plus RED means the migration broke
the daily driver; name the gate and stop. Do not propose a fix in the same
breath as the diagnosis.

SECOND, CAR 2, and only if I paste the second Botify MCP server's URL. If I did
not paste it, say so plainly for the second turn running and do not invent one.
If I did:
  - Say HOST or PATH, and name the exact filename token_path_for produces.
  - Rule on the actuator's output: gate3 printing "client_id from
    $MCP_OAUTH_CLIENT_ID" plus a gate5 GREEN is the OBSERVED portability
    answer; a gate4 authorization error is the falsification. Say which one
    fired and label the resulting claim OBSERVED, not INFERRED.
  - Only after a gate5 GREEN, propose the obtain_client_id patch that reads a
    pinned client_id from an existing token file so gate3 stops registering.
    Not before.

THIRD, and only if BOTH of the above came back green: the registry. Name its
columns — nickname, url, scope override, pinned client_id, pinned port,
enrollment flag — and say which of them the CAR 2 receipt just proved are worth
having. Do not write the file this turn; I want the schema argued before the
JSON exists.

Do NOT touch wallet.py. Do NOT delete mcp_botify_token.json in a patch — that
is my hand, after I see a check resolving the derived path.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

4: Prompt: The lane-label car landed (or did not — read the receipts, not my memory). Two probes are echoed into this compile. Name the LANE for each reading.

Rule first, one line each:

Probe 1. Does it print “agree: True”? If False, the two copies of token_path_for have drifted and everything below stops until that is fixed. Also report the “slug:” line unchanged, so the path-differentiated filename shape stays on the record.
Probe 2. Does the token line say “file lane” or “env lane”? file lane means the car landed and the label now names the rung that actually fired. env lane means it did not land — say so before ruling on anything else. Confirm the “creds” line still shows the (pre-derivation) tag.

Then, in this order, and only for what I actually pasted:

FIRST, the migration receipt. I will paste a hand-run of: python scripts/connectors/mcp_warm.py –refresh && python scripts/connectors/mcp.py https://mcp.botify.com –check You predicted TWO stderr notes — one from refresh(), one from resolve_token(). Rule on whether both appeared, and whether the check reached GREEN. Two notes plus GREEN is the full pass. One note plus GREEN means one fallback branch did not fire; say which one and stop. Any note plus RED means the migration broke the daily driver; name the gate and stop. Do not propose a fix in the same breath as the diagnosis.

SECOND, CAR 2, and only if I paste the second Botify MCP server’s URL. If I did not paste it, say so plainly for the second turn running and do not invent one. If I did:

Say HOST or PATH, and name the exact filename token_path_for produces.
Rule on the actuator’s output: gate3 printing “client_id from $MCP_OAUTH_CLIENT_ID” plus a gate5 GREEN is the OBSERVED portability answer; a gate4 authorization error is the falsification. Say which one fired and label the resulting claim OBSERVED, not INFERRED.
Only after a gate5 GREEN, propose the obtain_client_id patch that reads a pinned client_id from an existing token file so gate3 stops registering. Not before.

THIRD, and only if BOTH of the above came back green: the registry. Name its columns — nickname, url, scope override, pinned client_id, pinned port, enrollment flag — and say which of them the CAR 2 receipt just proved are worth having. Do not write the file this turn; I want the schema argued before the JSON exists.

Do NOT touch wallet.py. Do NOT delete mcp_botify_token.json in a patch — that is my hand, after I see a check resolving the derived path.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None this turn. Here’s the configuration info for the new server:

And so we try this:

Opus 5 Extra: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax — the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing I emit carries one.

The two rulings

#	Reading	Colour	BEFORE (operator lane)	AFTER (compile lane, LIVE)
1	`token_path_for` agreement	🟢	`agree: True`	`agree: True`
1	slug shape	—	`mcp.botify.com__second.json`	`mcp.botify.com__second.json`
2	token lane label	🟢	`env lane`	`file lane`
2	`(pre-derivation)` tag	⬜ VOID	not in probe output	not in probe output

1. agree: True in both lanes. The duplicated derivation has not drifted. slug: unchanged at mcp.botify.com__second.json, so a path-differentiated server files as <netloc>__<quoted-path>.json. CHANGES: nothing — the invariant holds and the guard stays.

2. file lane. The car landed, and the label now names the rung that actually fired. Corroborated by a third channel: the git diff telemetry in this compile shows that exact commit as HEAD~1..HEAD. CHANGES: the ATTRIBUTED-VOICE regression is closed on the first line a newcomer reads.

The probe could not answer the question I asked it

You asked me to confirm the (pre-derivation) tag. I cannot, and the reason is my fault. The pattern 'token :|creds :' matches the two header lines only. The tag lives on the continuation line — # mcp_botify_token (pre-derivation) -- ... — which contains neither literal and is filtered out.

Run THE DISCRIMINATION QUESTION on it: what does that probe print in the world where the tag is missing? The same two lines. It is a ritual for that half of its job, and I designed it that way last turn while congratulating myself for making it content-bounded rather than count-bounded. -A 1 fixes it and is in the roster below.

What I can say: # creds : 1 warmed file(s) proves the block renders and the loop ran, and only LEGACY_TOKEN_FILE.is_file() can put a file in that list when TOKEN_DIR does not exist. So the tag is almost certainly there. Almost certainly is not a receipt.

FIRST — the migration receipt is still absent

Third turn running. You wrote “I will paste a hand-run of” the refresh-plus-check chain; it is not in this payload. Section 3 is patch / app / d / m / git push and nothing else. The GREEN chain earlier in the transcript predates all of CAR 1 and is a stale BEFORE wearing an AFTER’s label. I am not ruling on it.

Two stderr notes plus GREEN remains the owed reading. It is one command.

SECOND — CAR 2 is dead, and not in the way it was supposed to die

The URL arrived. It differs by HOST and PORT and PATH — the first server exercised none of those three.

token_path_for("https://irf.production.botify.com:3615/mcp") produces:

irf.production.botify.com:3615__mcp.json

⚠️ That hostname rode inside your [[[private]]] markers; my prose is outside them. scrub irf.production.botify.com before this becomes an article, and the substitution covers this turn’s text retroactively when sanitizer.py runs.

The actuator never reached the question it was built to answer. It died at gate1, in discover(), before obtain_client_id was called — so MCP_OAUTH_CLIENT_ID was read by nothing and MCP_OAUTH_REDIRECT_PORT bound nothing. Neither the success signature (gate3 GREEN: client_id from $MCP_OAUTH_CLIENT_ID) nor the falsification signature (a gate4 authorization error) fired.

Client-id portability across resources therefore remains INFERRED, exactly as it was, with one thing changed for the worse: it no longer has a cheap settling move, because this server cannot settle it. That needs a third server that is OAuth under app.botify.com, or a second resource under mcp.botify.com.

obtain_client_id stays unpatched.

What server two actually is

Its own config answers it, and the answer is that this is not an OAuth server at all:

"Authorization:${TOKEN_HEADER}" with TOKEN_HEADER = "Token YOUR_TOKEN" → the wire header is Authorization: Token <value>. Not Bearer. That is the Botify API-token grammar — the same credential class that produced the 2026-07-29 HTTP 401 against mcp.botify.com, which is why mcp_warm.py exists.
A static pre-shared header means no authorization server, no discovery chain, no refresh, no five-minute clock.
npx -y mcp-remote ... --transport http-only is a stdio bridge for clients that cannot speak Streamable HTTP. mcp.py speaks it natively, so the bridge is irrelevant to us — we talk to the endpoint directly. http-only also says no SSE framing, which parse_body() already handles either way.

So “Botify MCP” is two auth stories, not one. The credential KIND is per-server, never per-vendor. That is the finding of this turn.

And a second, independent defect the 403 exposed

RFC 9728 forms the metadata URL by inserting /.well-known/oauth-protected-resource between host and path, not appending it after. For https://host/mcp the conformant URL is:

https://host/.well-known/oauth-protected-resource/mcp

discover() builds resource.rstrip("/") + "/.well-known/oauth-protected-resource", which appends. For https://mcp.botify.com/ — empty path — both constructions coincide exactly, which is why it has always worked and why nobody looked. SINGLE-CANDIDATE BLINDNESS in the URL builder, invisible until the first path-bearing resource, which is today.

I do not know that this caused the 403. Two rival hypotheses, both consistent with one status code:

H1 — the server does OAuth and we asked the wrong URL.
H2 — the server does no OAuth and publishes no such document; the config is telling the truth.

The config is a strong prior for H2. Two unauthenticated GETs discriminate them for free, and they are in the roster.

THIRD — the registry gate is not met

You conditioned the schema argument on both of the above coming back green. Neither did. Not writing it, not arguing it.

One thing the receipt banked for whenever it is argued, because it is earned rather than speculated: auth scheme and auth source are not derivable from a URL. Bearer-vs-Token, and warm-vs-static, are per-server facts no amount of path derivation supplies. That is a genuinely new column and a different justification than the nickname convenience I argued two turns ago. Everything else on my old column list is still speculation.

Housekeeping, two lines

adhoc.txt carries 3 scripts/foo_cartridge.py and 3 scripts/foo_replay.py — stray 3 prefixes. The compiler’s DE-PREFIXED COMMAND hint caught both and skipped them, so those two files are not in this context. That branch is compile-lane-exclusive and it just did its job twice.

Separately: probe 1 is a permanent invariant guard, not a straddle. It will print agree: True forever, which is the shape RETIRE-THE-CANARY warns about. It belongs in tests/ beside test_apply_airlock.py, where pytest runs it for free and it stops spending payload budget. Not a car; a note.

1. PROBES

Probe 1 is the widened identity read. -A 1 restores the continuation lines the old pattern filtered out, so the (pre-derivation) tag becomes visible for the first time. Before this widening it printed two lines; after, roughly four.

Probe 2 is free and settles the colon question as a receipt rather than as my arithmetic. Expect irf.production.botify.com:3615__mcp.json. A colon is legal on Linux and inside WSL, tolerated by POSIX on macOS, and illegal on native Windows — worth knowing, not worth patching against a hypothetical, since no file will ever be written at that path if H2 holds.

Probes 3 and 4 discriminate H1 from H2. wk_inserted=200 means the server does OAuth and discover()’s URL builder is the bug. Both non-200 means the document is not there and the static-token reading stands. Both send no credential.

Probe 5 is the control that keeps probes 7 and 8 honest. An unset variable makes curl send an empty credential and get the same 401 a wrong grammar would — THE DISCRIMINATION QUESTION failing inside the instrument. Read this line first or the two below it mean nothing.

Probes 6, 7 and 8 are the auth-grammar discriminator: anonymous control, then each scheme. -o /dev/null discards every body and -w prints only a status code, so no credential can reach the payload; the command text carries the env var NAME and never its value. If bearer returns 200, mcp.py already works against this server today and there is no patch at all — which would be the cheapest possible outcome and is exactly why this runs before anything is written.

This payload is 278k tokens for a two-file connector ride. The rolling pin (60k), foo_files.py (74k), flake.nix (28k), prompt_foo.py (42k) and GLOSSARY.md (7.5k) are 76% of it and nothing in this train touches any of them. Drop all five, plus apply.py, .gitattributes, .gitignore, requirements.in, __init__.py and pyproject.toml.

3. PATCHES

No repo patches required. Three candidate edits are on the table and every one of them has an unrun probe standing in front of it:

an --auth-scheme flag on make_client() — pointless if bearer=200, and the wrong shape if scheme_token also fails
an RFC 9728-conformant discovery URL in discover() — pointless if wk_inserted is not 200
escaping the netloc in token_path_for() — no file will ever be written at that path if H2 holds

Patching any of them now would be patching around a falsified premise instead of stopping at it.

No ignition required. Every probe invokes its target at call time.

Still owed, operator lane, and it is one command:

python scripts/connectors/mcp_warm.py --refresh && python scripts/connectors/mcp.py https://mcp.botify.com --check

Predicted from raw source: two stderr notes — # refreshing the pre-derivation file mcp_botify_token.json IN PLACE from refresh(), and # mcp credential: reading the pre-derivation file ... from resolve_token — then mcp GREEN with auth=mcp_botify_token.json. One note instead of two is a finding.

4. PROMPT

Eight probes are echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each one CHANGES:

1. Probe 1 with -A 1. Does the (pre-derivation) tag appear now? Yes closes a
   VOID from last turn. No means the identity loop is not tagging the legacy
   file and that is a real defect, not a probe artifact — say which.
2. Probe 2. Print the filename verbatim. Confirm or correct my claim that the
   port survives into it unescaped.
3. Probes 3 and 4 together. wk_inserted=200 means the server DOES do OAuth and
   discover()'s appended URL is the bug (H1). Both non-200 means no document
   and the static-token reading stands (H2). A 200 on wk_appended would mean I
   read the RFC wrong — say so plainly if that is what happened.
4. Probe 5 BEFORE probes 6-8. If botify_token_set=no, probes 7 and 8 sent an
   empty credential and their status codes mean nothing; stop there and say so.
5. Probes 6, 7, 8 as a triple. Name which scheme, if either, reached 200, and
   what anon returned. bearer=200 means mcp.py already works and there is no
   patch to write at all — say that first if it is true.

Then emit AT MOST ONE car, chosen by what the readings actually licensed, and
say why the other two were not licensed:

CAR A — AUTH SCHEME. Only if scheme_token succeeded where bearer failed. A
  per-call auth scheme in make_client(), defaulting to Bearer so nothing about
  mcp.botify.com changes. Say how the scheme is SELECTED — flag, env var, or
  read from a file beside the credential — and argue that choice, because it is
  the first place a per-server fact has needed a home that is not a URL.

CAR B — DISCOVERY URL. Only if wk_inserted=200. Make discover() insert rather
  than append per RFC 9728. Name what this does to the mcp.botify.com path
  (empty path, so both constructions coincide) and give the probe that proves
  it did not regress the working server.

CAR C — NETLOC ESCAPE. Only if a token file will actually be written at a
  port-bearing path, which requires CAR A or CAR B to have landed first.

If NONE is licensed, say "no car licensed" and give me the next cheapest probe
instead. Do not invent a fourth car.

STILL OWED, and I will paste it if I ran it: the refresh+check migration
receipt against mcp.botify.com. Two stderr notes plus GREEN is the full pass.
One note plus GREEN means one fallback branch did not fire; name which and
stop. Any note plus RED means the migration broke the daily driver; name the
gate and stop.

Do NOT touch wallet.py. Do NOT patch obtain_client_id — client-id portability
is still INFERRED and this server cannot settle it. Do NOT write the registry.
Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

4: Prompt: Eight probes are echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each one CHANGES:

Probe 1 with -A 1. Does the (pre-derivation) tag appear now? Yes closes a VOID from last turn. No means the identity loop is not tagging the legacy file and that is a real defect, not a probe artifact — say which.
Probe 2. Print the filename verbatim. Confirm or correct my claim that the port survives into it unescaped.
Probes 3 and 4 together. wk_inserted=200 means the server DOES do OAuth and discover()’s appended URL is the bug (H1). Both non-200 means no document and the static-token reading stands (H2). A 200 on wk_appended would mean I read the RFC wrong — say so plainly if that is what happened.
Probe 5 BEFORE probes 6-8. If botify_token_set=no, probes 7 and 8 sent an empty credential and their status codes mean nothing; stop there and say so.
Probes 6, 7, 8 as a triple. Name which scheme, if either, reached 200, and what anon returned. bearer=200 means mcp.py already works and there is no patch to write at all — say that first if it is true.

Then emit AT MOST ONE car, chosen by what the readings actually licensed, and say why the other two were not licensed:

CAR A — AUTH SCHEME. Only if scheme_token succeeded where bearer failed. A per-call auth scheme in make_client(), defaulting to Bearer so nothing about mcp.botify.com changes. Say how the scheme is SELECTED — flag, env var, or read from a file beside the credential — and argue that choice, because it is the first place a per-server fact has needed a home that is not a URL.

CAR B — DISCOVERY URL. Only if wk_inserted=200. Make discover() insert rather than append per RFC 9728. Name what this does to the mcp.botify.com path (empty path, so both constructions coincide) and give the probe that proves it did not regress the working server.

CAR C — NETLOC ESCAPE. Only if a token file will actually be written at a port-bearing path, which requires CAR A or CAR B to have landed first.

If NONE is licensed, say “no car licensed” and give me the next cheapest probe instead. Do not invent a fourth car.

STILL OWED, and I will paste it if I ran it: the refresh+check migration receipt against mcp.botify.com. Two stderr notes plus GREEN is the full pass. One note plus GREEN means one fallback branch did not fire; name which and stop. Any note plus RED means the migration broke the daily driver; name the gate and stop.

Do NOT touch wallet.py. Do NOT patch obtain_client_id — client-id portability is still INFERRED and this server cannot settle it. Do NOT write the registry. Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None this turn.

And I added the instructions that I had received for the 2nd MCP server as deleteme.txt which might help.

Opus 5 Max: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax — the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing I emit carries one.

The rulings

All eight probe readings are compile lane (LIVE COMMAND RECEIPTS). Your hand-run of the same eight is operator lane. They agree everywhere except the token clock, which is elapsed time, not disagreement.

1. The (pre-derivation) tag appears. -A 1 surfaced line 6: mcp_botify_token (pre-derivation) -- EXPIRED 349s ago. CHANGES: the VOID from last turn is closed, and it was my probe that was broken, not the code. The identity loop tags correctly.

A free reading rode along: your operator tap said EXPIRED 2450s, the compile tap says EXPIRED 349s. The clock ran backward across the two taps, which is only possible because the refresh in section 3 landed between them. The straddle witnessed the ignition without being asked to.

2. second: irf.production.botify.com:3615__mcp.json. The port survives unescaped — my claim confirmed. CHANGES: nothing yet, because nothing will ever write that file (see ruling 5).

3. wk_appended=403, wk_inserted=404. H2 stands, and my RFC claim is neither confirmed nor refuted. Read the two codes against the anonymous POST: anon=403 is the same 403, so the entire /mcp prefix is behind the auth gate and the appended URL proved gating, not presence. The 404 on the RFC-conformant path is the informative one — that path space is served and the document is not there. CHANGES: CAR B is not licensed, and the append-versus-insert question stays OPEN and unwitnessed. Neither URL returned 200, so this server settles nothing about discover()’s construction. That needs a path-bearing OAuth server, which we do not have.

4. botify_token_set=yes. The control holds, so probes 7 and 8 are meaningful. CHANGES: it licenses ruling 5.

5. anon=403, bearer=403, scheme_token=200. Authorization: Token <BOTIFY_API_TOKEN> reaches 200 at initialize where Bearer does not. bearer is not 200, so mcp.py does not already work and there is a patch to write.

The load-bearing detail is that anon and bearer are the same 403. On this server a wrong grammar and no credential at all print identically — THE DISCRIMINATION QUESTION failing on the vendor’s side, which is why the anonymous control had to run and why the FDR needs to record which grammar was sent.

deleteme.txt corroborates from a second channel: the vendor’s own config sets TOKEN_HEADER = "Token YOUR_TOKEN". Wire and docs agree.

The migration receipt — full pass

Two stderr notes, both predicted, both present:

# refreshing the pre-derivation file mcp_botify_token.json IN PLACE — refresh()’s branch fired
# mcp credential: reading the pre-derivation file mcp_botify_token.json — resolve_token’s branch fired

Then mcp GREEN ... protocol=2025-06-18 session=no tools=42 auth=mcp_botify_token.json. Both fallback branches fired and the daily driver is unbroken. CAR 1’s migration story is banked, and the legacy file is now safe to delete by your hand after your next browser warm writes the derived path.

What server two actually is

Two auth stories under one vendor. Server one is OAuth 2.1 with a 300-second bearer, a discovery chain, and a refresh token. Server two is a static pre-shared header with a different scheme, no authorization server, no clock, no refresh. The credential KIND is per-server, never per-vendor — that is the finding of this turn, and it is the first fact in this whole thread that no amount of URL derivation can supply.

The npx mcp-remote --transport http-only wrapper in the config is a stdio bridge for clients that cannot speak Streamable HTTP. mcp.py speaks it natively, so we skip the bridge entirely.

The leak CAR 1 left behind

Read resolve_existing_token_file against the receipts. All three of MCP_BEARER_TOKEN, MCP_TOKEN_FILE and BOTIFY_TOKEN_FILE are unset — proven by identity() falling through to the file rung. So for any server whose derived file does not exist, the function returns LEGACY_TOKEN_FILE and mcp.py sends the mcp.botify.com OAuth bearer to that server.

mcp https://irf.production.botify.com:3615/mcp --check sends server one’s credential to server two today. Same company, so the blast radius is small, but it is structurally the exact cross-server hazard CAR 1 was built to remove, reintroduced by CAR 1’s own fallback branch.

The fix is derivation again and it is cheap: the legacy file records "resource": "https://mcp.botify.com/", so the fallback can read that field and refuse to answer for any other resource. That is its own car with its own straddle, and it is not this one — I was told at most one, and the auth scheme is what the receipts licensed. Until it lands, --token-env is the explicit workaround and it appears in every server-two invocation below.

A hazard in your working tree

deleteme.txt is untracked, not in .gitignore, and carries the internal production hostname. m() opens with git add -A. The next m commits it to a public repo. Delete it or ignore it before your next commit.

CAR A — the auth scheme, and where the fact lives

How the scheme is selected: an explicit --auth-scheme flag, defaulting to Bearer. Three candidates, and the argument matters because this is the first per-server fact that has needed a home outside the URL.

An environment variable is rejected outright. MCP_AUTH_SCHEME=Token is shell-global, so exporting it for server two silently breaks server one in the same terminal. A per-server fact in a per-shell variable is the wrong shape by construction, and the failure is invisible until the working server starts 403ing for no stated reason.

A file beside the credential is the right second rung, and it is deliberately not in this car. The derived token path already gives every server a private home, and the OAuth record already carries "token_type" — which for Botify is literally "Bearer", the standard OAuth 2.1 field naming exactly this. Reading it costs four lines. But the scheme must come from the same source as the credential, or we recreate the lane-label defect we fixed last turn: attributing a scheme from a file when the credential came from an env var. Doing that honestly means resolve_token returns a triple instead of a pair, which is a signature change across four call sites and deserves its own car and its own straddle.

The flag is what the receipt licensed and it works today, because rung 1 of resolve_token accepts --token-env, so server two is reachable in one command with no additional patch:

mcp https://irf.production.botify.com:3615/mcp --check --auth-scheme Token --token-env BOTIFY_API_TOKEN

Verbose, explicit, and it names both per-server facts at the point of use. The file-derived rung then makes it terse later, once the plumbing exists to do it without lying about provenance.

The FDR records the scheme in the same car. A recorder that captures the credential’s env NAME but not the auth GRAMMAR would be blind to the one variable this turn discovered, and two flights — one 403, one 200 — would write indistinguishable receipts. The frame doc moves with it, per FRAME-DOC COROLLARY.

Ten blocks, all small.

Ignition: none required. Every probe imports or invokes the patched file at call time.

Why CAR B and CAR C were not licensed

CAR B required wk_inserted=200. It read 404. Neither URL returned 200, so this server has no protected-resource document at either construction and cannot adjudicate the RFC question. Patching discover() now would be patching around a falsified premise.

CAR C required a token file to actually be written at a port-bearing path, which requires an OAuth flow to reach gate5 against that server. Server two has no OAuth flow, so irf.production.botify.com:3615__mcp.json will never exist. Probe 2’s filename is a computed string with no file behind it. Escaping it now would be defending against a hypothetical.

1. PROBES

.venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp; c=mcp.make_client("XX"); print("default:", c.headers["authorization"]); c.close(); c2=mcp.make_client("XX","Token"); print("scheme :", c2.headers["authorization"]); c2.close()' 2>&1 | tail -3
.venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp; p,legacy = mcp.resolve_existing_token_file("https://irf.production.botify.com:3615/mcp"); print("server_two_resolves_to:", p.name, "legacy_fallback:", legacy)'
out=$(.venv/bin/python scripts/connectors/mcp.py https://irf.production.botify.com:3615/mcp --check --auth-scheme Token --token-env BOTIFY_API_TOKEN 2>&1); echo "srv2_check_exit=$?"; printf '%s\n' "$out" | tail -3

Probe 1 is CAR A’s straddle and it opens no socket. Before the car it ends in a TypeError on the second call; after, it prints Bearer XX then Token XX. The token is the literal string XX, so nothing real crosses the boundary.

Probe 2 is the leak, read as source rather than performed. It sends nothing. Expect mcp_botify_token.json True — that boolean is the whole indictment: server two currently resolves server one’s OAuth credential. It is the BEFORE tap for the scoping car, and it is the reason probe 3 carries --token-env.

Probe 3 is the payoff and it is the first --check in this project’s history that can print GREEN from the compile lane, because a static credential has no five-minute clock to outrun. The whole command names only env-var NAMES; --check’s success line prints auth= and scheme= and never a value. A gate name instead of GREEN is a real finding: initialize returned 200 to curl, but nothing has ever proven the handshake completes or that tools/list answers.

2. NEXT CONTEXT

! .venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp; c=mcp.make_client("XX"); print("default:", c.headers["authorization"]); c.close(); c2=mcp.make_client("XX","Token"); print("scheme :", c2.headers["authorization"]); c2.close()' 2>&1 | tail -3
! .venv/bin/python -c 'import sys; sys.path.insert(0,"scripts/connectors"); import mcp; p,legacy = mcp.resolve_existing_token_file("https://irf.production.botify.com:3615/mcp"); print("server_two_resolves_to:", p.name, "legacy_fallback:", legacy)'
! out=$(.venv/bin/python scripts/connectors/mcp.py https://irf.production.botify.com:3615/mcp --check --auth-scheme Token --token-env BOTIFY_API_TOKEN 2>&1); echo "srv2_check_exit=$?"; printf '%s\n' "$out" | tail -3
scripts/connectors/mcp.py

mcp_warm.py comes out — nothing in this train touches it. So do the rolling pin, GLOSSARY.md, foo_files.py, flake.nix, prompt_foo.py, apply.py, .gitattributes, .gitignore, requirements.in, __init__.py, pyproject.toml and deleteme.txt. This compile is 292k tokens for a one-file connector edit; the next one should be under 20k.

Also fix the two stray 3 prefixes on the foo_cartridge / foo_replay lines while you are in ahe. The compile-lane DE-PREFIXED COMMAND hint caught both again this turn, which means those two files have been silently absent from context for four compiles.

3. PATCHES

CAR A above, ten blocks, one file. Choreography: patch, app, d, m, then blast.

Ignition: none required.

4. PROMPT

CAR A landed (or did not — read the receipts, not my memory). Three probes are
echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each one CHANGES:

1. Probe 1. Does it print "default: Bearer XX" then "scheme : Token XX"? A
   TypeError means the car did not land — say so before ruling on anything
   else. Two correct lines means make_client can now speak both grammars and
   the Bearer default is unchanged, which is the no-regression half.

2. Probe 2. Print the boolean verbatim. legacy_fallback: True confirms server
   two still resolves server one's OAuth credential when --token-env is
   omitted. That is the standing leak and it is the premise of the car below.

3. Probe 3. Did srv2_check_exit read 0 with a "mcp GREEN" line? If yes, name
   the protocol string, the session field, the tool count, and the scheme, and
   say plainly that this is the first compile-lane GREEN this project has ever
   produced — a static credential outlives the compile where a 300-second
   bearer cannot. If it read nonzero, name the GATE (gate1 no token, gate2
   handshake, gate3 tools/list) and STOP. A 200 on initialize from curl does
   not prove the handshake completes, and diagnosing a gate is not the same
   turn as fixing it.

Then emit AT MOST ONE car.

CAR D — SCOPE THE LEGACY FALLBACK. Only if probe 2 reads True.
  resolve_existing_token_file returns LEGACY_TOKEN_FILE for ANY server whose
  derived file is absent, so server one's bearer is offered to every other
  server. The legacy file records its own "resource" field; read it and return
  the legacy path ONLY when that resource matches the server being asked for.
  Say what the function returns when the resource does not match — the derived
  path that does not exist yet, so the caller falls through to BOTIFY_API_TOKEN
  and the ladder keeps working. Give me the straddle: probe 2 must flip from
  True to False while a mcp.botify.com resolution stays on the legacy file.

If probe 3 came back RED, emit NOTHING and give me the next cheapest probe
against the gate it named instead. Do not fix a gate and scope a fallback in
the same turn.

If probe 3 came back GREEN, ALSO answer this, in prose, no patch: the FDR
receipt for that flight now carries auth_scheme. Read the newest file under
browser_cache/mcp/ for that host if I paste it, and tell me whether the frame
records enough to replay the call — what is present, what is missing, and
whether body_sha256 without a body store is sufficient for the D0/D1/D2
adjudicator that is still owed from three turns ago.

Do NOT touch wallet.py. Do NOT patch obtain_client_id — client-id portability
across resources is still INFERRED and this vendor cannot settle it, because
server two runs no authorization server at all. Do NOT write the registry file.
Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

5. EXTERNAL DELIVERABLES

None this turn. One housekeeping action outside the patch train: delete deleteme.txt or add it to .gitignore before your next m, since git add -A will otherwise commit an internal production hostname to a public repository.

4: Prompt: CAR A landed (or did not — read the receipts, not my memory). Three probes are echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each one CHANGES:

Probe 1. Does it print “default: Bearer XX” then “scheme : Token XX”? A TypeError means the car did not land — say so before ruling on anything else. Two correct lines means make_client can now speak both grammars and the Bearer default is unchanged, which is the no-regression half.
Probe 2. Print the boolean verbatim. legacy_fallback: True confirms server two still resolves server one’s OAuth credential when –token-env is omitted. That is the standing leak and it is the premise of the car below.
Probe 3. Did srv2_check_exit read 0 with a “mcp GREEN” line? If yes, name the protocol string, the session field, the tool count, and the scheme, and say plainly that this is the first compile-lane GREEN this project has ever produced — a static credential outlives the compile where a 300-second bearer cannot. If it read nonzero, name the GATE (gate1 no token, gate2 handshake, gate3 tools/list) and STOP. A 200 on initialize from curl does not prove the handshake completes, and diagnosing a gate is not the same turn as fixing it.

Then emit AT MOST ONE car.

CAR D — SCOPE THE LEGACY FALLBACK. Only if probe 2 reads True. resolve_existing_token_file returns LEGACY_TOKEN_FILE for ANY server whose derived file is absent, so server one’s bearer is offered to every other server. The legacy file records its own “resource” field; read it and return the legacy path ONLY when that resource matches the server being asked for. Say what the function returns when the resource does not match — the derived path that does not exist yet, so the caller falls through to BOTIFY_API_TOKEN and the ladder keeps working. Give me the straddle: probe 2 must flip from True to False while a mcp.botify.com resolution stays on the legacy file.

If probe 3 came back RED, emit NOTHING and give me the next cheapest probe against the gate it named instead. Do not fix a gate and scope a fallback in the same turn.

If probe 3 came back GREEN, ALSO answer this, in prose, no patch: the FDR receipt for that flight now carries auth_scheme. Read the newest file under browser_cache/mcp/ for that host if I paste it, and tell me whether the frame records enough to replay the call — what is present, what is missing, and whether body_sha256 without a body store is sufficient for the D0/D1/D2 adjudicator that is still owed from three turns ago.

Do NOT touch wallet.py. Do NOT patch obtain_client_id — client-id portability across resources is still INFERRED and this vendor cannot settle it, because server two runs no authorization server at all. Do NOT write the registry file. Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None this turn.

Opus 5 Max: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax — the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing I emit carries one.

The three rulings

All three probe readings below are compile lane (LIVE COMMAND RECEIPTS). Your hand-run of the same three, pasted in section 1, is operator lane and is the BEFORE tap — it predates CAR A. The straddle is clean in all three.

#	Reading	Colour	BEFORE (operator)	AFTER (compile, LIVE)
1	`make_client` grammars	🟢	`TypeError: make_client() takes 1 positional argument`	`default: Bearer XX` / `scheme : Token XX`
2	legacy fallback scope	🔴	`legacy_fallback: True`	`legacy_fallback: True`
3	server two check	🟢	`srv2_check_exit=2`, `unrecognized arguments: --auth-scheme`	`srv2_check_exit=0`, `mcp GREEN`

1. default: Bearer XX then scheme : Token XX. CAR A landed. CHANGES: make_client now speaks both grammars and the Bearer default is byte-unchanged, which is the no-regression half — server one’s path cannot have moved.

2. server_two_resolves_to: mcp_botify_token.json legacy_fallback: True, verbatim, identical in both lanes. CHANGES: nothing yet — the leak is confirmed rather than closed, and it is the premise of the only car below.

3. srv2_check_exit=0 with mcp GREEN https://irf.production.botify.com:3615/mcp protocol=2025-06-18 session=yes tools=56 auth=BOTIFY_API_TOKEN scheme=Token.

Protocol 2025-06-18. Session yes. Tools 56. Scheme Token. Auth from BOTIFY_API_TOKEN, which means rung 1 fired on --token-env and the file rung was never reached — the explicit workaround did exactly its job and no credential crossed a server boundary.

And yes: this is the first compile-lane GREEN this project has produced. A static credential has no five-minute clock to outrun.

Three findings the receipt carried that nobody asked for

`session=yes` discharges a banked debt

Every mcp.botify.com flight in this corpus has read session=no, twice, 23 days apart. Server two returned an Mcp-Session-Id on initialize, post() threaded it back, and tools/list answered with 56 tools.

The constitution’s MCP RECEIPT RULE says Mcp-Session-Id “is NOT witnessed against this vendor” and remains witnessed only by the fault harness — “which shares mcp.py’s spec reading, and is therefore the TAUTOLOGY the rule already warned about.” That tautology is now broken. The header round trip is OBSERVED against a server of independent authorship, and all three protocol strings have moved from INFERRED to OBSERVED.

Stated precisely, because the distinction is the whole value: what is witnessed is that the server issues a session id and that our client round-trips it correctly. Whether the server enforces it is still unwitnessed — that needs the raw-httpx control the fault harness runs, posting with no session header and being refused.

The lane rule was over-scoped, and this receipt falsifies it as written

foo_files.py banks: “mcp.py --check is STRUCTURALLY INCAPABLE of printing GREEN in the compile lane, because a compile always runs minutes after a human ignition.”

That generalized from a 300-second credential to the lane. The correct scope is the credential’s life: a credential shorter-lived than the human loop cannot be witnessed GREEN from a compile; a static credential can be, forever. The rule is right about server one and wrong as a law. Owed as a constitution amendment, not patched this turn — you said at most one car and CAR D is what the receipts licensed.

D1 drift is now the ordinary case, twice over

Server one: 38 tools / 56,239 bytes on 2026-08-06 → 42 tools / 65,771 bytes on 2026-08-29. Server two: 56 tools. tools/list is D1 against both, and the adjudicator that is still owed will spend most of its life reporting drift.

The FDR question — the file was not pasted

You conditioned it on “if I paste it.” You did not. The receipt path is named in probe 3’s output but its contents are not in this payload, so what follows is read from raw source (mcp.py’s frame doc and _record_exchange, both in context), not from the artifact. Labeled accordingly. A probe below turns it into an OBSERVED reading next turn.

Present, and sufficient to re-issue the call: server URL, verb, tool name, args_raw byte-for-byte from argv, protocol_version_sent, client_info, auth_env (the NAME), and now auth_scheme. That is every input make_client and post consume except the credential value — which is correctly absent and is re-resolved by name at replay time. Nothing in a replay needs to read a secret out of a receipt.

Missing, and it decides what the adjudicator can be: the body. body_sha256 answers exactly one question — same or different.

D0 — sufficient, and it is the right instrument. A D0 claim is “identical bytes forever”; a hash match confirms it and a mismatch falsifies it, and you never need the body to know which.
D1 — insufficient. A mismatch is expected, so the hash yields one bit of information about a case where the interesting fact is what changed. Apply it to 38→42 tools and it prints D1 DRIFT and stops, unable to say that four tools were added.
D2 — irrelevant. Adjudication is refused by definition.

So the adjudicator can be built today for D0 only, honestly, with the D1 branch printing “drift, body not retained” rather than pretending. Widening it to D1 needs a body store first, and that is a scoped cost you can now estimate from receipts: ~66KB per tools/list flight, 15 flights on server one so far, in a gitignored directory. That is a ride, not a footnote, and it is the named prerequisite the player has been waiting on for four turns.

The hazard that did not fire, and I cannot say why

deleteme.txt is untracked, not ignored, and carries the internal production hostname. m() in flake.nix opens with git add -A, so it should have been swept into the first commit of section 3. Every one of the ten commit diffstats reads “1 file changed”, so it was not.

An unexplained non-failure is not a guarantee. Either that shell predates the git add -A fix — which is the IGNITION RULE wearing a bug’s costume, and is exactly the shape banked on 2026-08-21 — or something else intervened. Delete the file or ignore it before your next m; do not rely on whatever spared you.

Separately: the hostname is now throughout this transcript. scrub irf.production.botify.com before publishing, and the substitution covers this turn retroactively.

CAR D — scope the legacy fallback

Probe 2 read True, so this is licensed and it is the only thing licensed.

resolve_existing_token_file returns LEGACY_TOKEN_FILE for any server whose derived file is absent. All three env rungs are unset — proven by identity() falling through to the file rung — so mcp <any-server> without --token-env offers the mcp.botify.com OAuth bearer to that server. That is the cross-server hazard CAR 1 was built to remove, reintroduced by the compatibility branch that carried CAR 1’s migration.

How it decides: the legacy record names the resource it was minted for. Run that name through token_path_for — the same derivation, not a second normalization rule — and compare paths. One rule in one file; a trailing slash never gets to decide who receives a credential.

What it returns on a mismatch: the derived path, which does not exist, so resolve_token’s file rung finds nothing and the ladder falls through to BOTIFY_API_TOKEN exactly as it does on a cold machine. Nothing that works today stops working.

Fail closed: an unreadable file, a non-dict body, or a missing resource field all decline. A credential that cannot prove where it belongs does not get sent. The non-dict guard is the lesson wallet.py already paid for — connectors.json carries non-object top-level entries, and every reader type-checks before descending.

The decline is loud. Silent refusal and no-legacy-file-at-all would print identically while the operator knows a credential exists; one stderr line names the decision.

Ignition: none required. Every probe imports the patched module at call time.

The straddle, and its regression branch named in advance. Probe 1 below reads both resources in one command.

srv2 must flip True → False, resolving to irf.production.botify.com:3615__mcp.json, with the decline note on stderr.
srv1 must stay mcp_botify_token.json True. That is the no-regression half, and it depends on an INFERRED fact: that the legacy file’s resource field holds https://mcp.botify.com/. The earlier jq keys proved the field exists; nothing has read its value. If srv1 also flips to False, that is a regression and the finding — the field holds something other than what mcp_warm.py’s DEFAULT_RESOURCE writes, and the car comes back out before anything else happens.

Probe 1 is CAR D’s straddle and it reads both sides of the scoping decision in one command. It opens no socket, sends nothing, and touches no credential value.

Probe 2 is unchanged from last turn and is now the no-regression witness for server two: CAR D must not disturb a call that names --token-env explicitly, because rung 1 short-circuits before the resolver is reached. It also re-writes the FDR receipt that probe 3 reads.

Probe 3 turns the FDR analysis above from source-reading into observation. response_headers is deliberately omitted — a remote service can put cookies or signed locations there. The session ids are projected as booleans, not values: a session id is a live capability for the duration, and the same discipline that keeps token values off disk keeps it out of the payload. Ordering is not a DOUBLE-TAP lag — probe 2’s atexit flush completes before probe 3’s process starts, so it reads this compile’s own receipt.

Probe 1 from last turn (make_client grammars) is retired. It straddled cleanly in both directions and would now print the same two lines forever, which is the RETIRE-THE-CANARY shape. It belongs in tests/ beside test_apply_airlock.py, alongside the token_path_for agreement guard retired two turns ago — that is a small ride of its own whenever you want it.

scripts/connectors/mcp.py

One file. This compile is 297k tokens for a one-file, two-block edit: the rolling pin (61k), foo_files.py (75k), prompt_foo.py (42k), flake.nix (28k) and GLOSSARY.md (7.5k) are 72% of it and nothing in this train touches any of them. Drop all five, plus apply.py, .gitattributes, .gitignore, requirements.in, __init__.py and pyproject.toml.

Also fix the two stray 3 prefixes on the foo_cartridge / foo_replay lines while you are in ahe. The compile-lane DE-PREFIXED COMMAND hint caught both again — fifth consecutive compile — which means those two files have been silently absent from context that whole time.

3. PATCHES

CAR D above, two blocks, one file. Choreography: patch, app, d, m, then blast.

Ignition: none required.

Not emitted, and why: no other car was licensed. Client-id portability across resources remains INFERRED and this vendor cannot settle it, because server two runs no authorization server at all. The discover() append-versus-insert question remains OPEN — neither URL returned 200 last turn, so nothing adjudicated it. The netloc escape defends a file that will never be written. The constitution’s compile-lane-GREEN amendment is owed but is a second car.

4. PROMPT

CAR D landed (or did not — read the receipts, not my memory). Three probes are
echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each CHANGES:

1. Probe 1, srv2 line. Does it read
   "irf.production.botify.com:3615__mcp.json False"? That is the leak closed.
   Still "mcp_botify_token.json True" means the car did not land — say so
   before ruling on anything else.

2. Probe 1, srv1 line. Does it STILL read "mcp_botify_token.json True"? That is
   the no-regression half and it is the one I actually care about. If srv1 also
   flipped to False, the legacy file's "resource" field does not hold what
   mcp_warm.py's DEFAULT_RESOURCE writes, the daily driver just lost its
   credential, and that is a REGRESSION: name it, stop, and do not propose a
   fix in the same breath.

3. Probe 2. srv2_check_exit and the GREEN line. Confirm protocol, session, tool
   count and scheme are unchanged from last compile. Any change is a finding,
   not noise — a tool count that moved is D1 drift on a second server.

4. Probe 3. The FDR projection for server two. Answer three things from the
   ARTIFACT rather than from source: does auth_scheme record "Token"; do the
   session booleans read true on the exchanges that carry one; and how many
   exchanges are there. Then say whether the artifact matches what I predicted
   from raw source last turn, and name any field I got wrong.

Then emit AT MOST ONE car, and say why the others were not licensed:

CAR E — THE D0 ADJUDICATOR. Only if probes 1 and 2 both came back clean. A
  replay subcommand that reads a receipt, re-issues from server + verb + tool +
  args_raw + auth_env + auth_scheme, and rules ONLY on D0: hash match or
  falsified. D1 prints "drift, body not retained" and refuses to characterise
  it; D2 refuses to rule at all and prints "new observation at <ts>". Do NOT
  build a body store in the same car — name it as the prerequisite for D1 and
  give me its size estimate from the receipts we already have. Say how the
  credential is re-resolved at replay time and confirm no secret is read from
  the receipt.

CAR F — THE LANE-SCOPE AMENDMENT. A foo_files.py edit correcting the standing
  claim that mcp.py --check cannot print GREEN in the compile lane. The
  property belongs to the CREDENTIAL's life, not the lane, and this turn's
  static-credential GREEN is the falsifying receipt. Cite the receipt line.

If probe 1's srv1 line regressed, emit NOTHING and give me the cheapest probe
that reads the legacy file's "resource" field value instead.

Do NOT touch wallet.py. Do NOT patch obtain_client_id. Do NOT write the
registry file. Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

5. EXTERNAL DELIVERABLES

None this turn. Two housekeeping actions outside the patch train: delete deleteme.txt or add it to .gitignore, and run scrub irf.production.botify.com before this thread becomes an article.

4: Prompt: CAR D landed (or did not — read the receipts, not my memory). Three probes are echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each CHANGES:

Probe 1, srv2 line. Does it read “irf.production.botify.com:3615__mcp.json False”? That is the leak closed. Still “mcp_botify_token.json True” means the car did not land — say so before ruling on anything else.
Probe 1, srv1 line. Does it STILL read “mcp_botify_token.json True”? That is the no-regression half and it is the one I actually care about. If srv1 also flipped to False, the legacy file’s “resource” field does not hold what mcp_warm.py’s DEFAULT_RESOURCE writes, the daily driver just lost its credential, and that is a REGRESSION: name it, stop, and do not propose a fix in the same breath.
Probe 2. srv2_check_exit and the GREEN line. Confirm protocol, session, tool count and scheme are unchanged from last compile. Any change is a finding, not noise — a tool count that moved is D1 drift on a second server.
Probe 3. The FDR projection for server two. Answer three things from the ARTIFACT rather than from source: does auth_scheme record “Token”; do the session booleans read true on the exchanges that carry one; and how many exchanges are there. Then say whether the artifact matches what I predicted from raw source last turn, and name any field I got wrong.

Then emit AT MOST ONE car, and say why the others were not licensed:

CAR E — THE D0 ADJUDICATOR. Only if probes 1 and 2 both came back clean. A replay subcommand that reads a receipt, re-issues from server + verb + tool + args_raw + auth_env + auth_scheme, and rules ONLY on D0: hash match or falsified. D1 prints “drift, body not retained” and refuses to characterise it; D2 refuses to rule at all and prints “new observation at ". Do NOT build a body store in the same car — name it as the prerequisite for D1 and give me its size estimate from the receipts we already have. Say how the credential is re-resolved at replay time and confirm no secret is read from the receipt.

CAR F — THE LANE-SCOPE AMENDMENT. A foo_files.py edit correcting the standing claim that mcp.py –check cannot print GREEN in the compile lane. The property belongs to the CREDENTIAL’s life, not the lane, and this turn’s static-credential GREEN is the falsifying receipt. Cite the receipt line.

If probe 1’s srv1 line regressed, emit NOTHING and give me the cheapest probe that reads the legacy file’s “resource” field value instead.

Do NOT touch wallet.py. Do NOT patch obtain_client_id. Do NOT write the registry file. Do NOT delete mcp_botify_token.json in a patch; that is my hand.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None on this turn.

Opus 5 Extra: Context verified.

Render canary fired. It reached me wrapped in markdown link syntax — the decisive reading. Every bare www-prefixed token in this payload is suspect. Nothing I emit carries one.

The four rulings

Probe readings labeled compile are this compile’s LIVE COMMAND RECEIPTS. Your hand-run pasted in sections 1 and 3 is the operator lane and is the BEFORE tap — it predates CAR D, and it appears twice, which is a free confirmation.

#	Reading	Colour	BEFORE (operator)	AFTER (compile, LIVE)
1	srv2 resolution	🟢	`mcp_botify_token.json True`	`irf...__mcp.json False` + decline note
2	srv1 resolution	🟢	`mcp_botify_token.json True`	`mcp_botify_token.json True`
3	server two check	🟢	exit 0, GREEN	exit 0, GREEN, identical fields
4	FDR artifact	🟢	—	`auth_scheme: "Token"`, 3 exchanges

1. srv2: irf.production.botify.com:3615__mcp.json False, preceded on stderr by # mcp credential: declining mcp_botify_token.json for ... -- it was minted for a different resource. CHANGES: the cross-server leak is closed, and the decline is loud rather than silent, so “no legacy file at all” and “legacy file declined” no longer print identically.

2. srv1: mcp_botify_token.json True. No regression. CHANGES: it also settles an INFERRED fact I flagged in advance — the legacy file’s resource field does hold what mcp_warm.py’s DEFAULT_RESOURCE writes, since token_path_for on it lands exactly on mcp.botify.com.json. That was the branch that would have cost you your daily driver, and it held.

3. srv2_check_exit=0, protocol=2025-06-18 session=yes tools=56 auth=BOTIFY_API_TOKEN scheme=Token. Every field unchanged from last compile. CHANGES: nothing — and that is the finding. Server one drifted 38→42 tools across 23 days; server two is byte-stable across two flights minutes apart, initialize at 2422 bytes and tools/list at 31314 both times. No D1 drift to report.

4. From the artifact, not from source: auth_scheme records "Token". Three exchanges. The session booleans read ret=true / sent=false on initialize, then sent=true / ret=false on both subsequent exchanges. CHANGES: auth_scheme is now OBSERVED in a written receipt rather than inferred from a patch that landed.

Where my source-reading prediction was thin

I predicted three exchanges and auth_scheme: "Token", and both hold. What I described loosely was the session shape — I said the booleans would “read true on the exchanges that carry one,” which flattens an asymmetry the artifact makes visible. The server returns the id exactly once, at initialize, and the client sends it on the two that follow. That is a handoff, legible in four booleans, and it is a stronger reading than “a session exists.”

One field I did not flag at all, and it is the one that matters below: dclass: null. A --check flight arms the receipt with no determinism class, because check() calls arm_receipt without one.

The finding that holds CAR E

The prompt licensed CAR E on probes 1 and 2 coming back clean. They did. I am holding it anyway, and the reason is a census I can read off the receipts already in hand.

arm_receipt is called four ways. For check it passes no tool, no raw_args, no dclass. For tools/list it passes no tool, no raw_args, no dclass. Only the tools/call path passes all three. So a replay subcommand that re-issues “from server + verb + tool + args_raw” has nothing to re-issue for any receipt whose verb is not tools/call.

Now count them. The 2026-08-29 listing showed 14 receipts under mcp.botify.com, of which the five newest names were four __check and one __tools_call from 2026-07-29. Server two has added three more, all __check. So the entire corpus holds — as far as any receipt in this thread has shown — exactly one replayable receipt, it is a month old, its credential has rotated since, and its server’s tool list has drifted 38→42 in the interim, which makes it D1.

That means a D0-only adjudicator built today would ship with zero D0 specimens. Its pass branch would be unwitnessed on day one and its only reachable output would be drift, body not retained — REFUSAL-ONLY WITNESS by construction, in a machine whose entire job is issuing verdicts. That is the shape the constitution already names, and building it into a new subcommand deliberately would be worse than stumbling into it.

The prerequisite is cheap and it is not a body store. It is one declared tools/call flight against something whose output genuinely does not move, so the adjudicator has a specimen on both branches before it exists. Whether such a tool exists on either server is itself unknown — that is a real question, not a formality, and tools/list is D1 on both.

The body store stays the second prerequisite, for D1 only, and the receipts now size it: 65,771 bytes for server one’s tools/list, 31,314 for server two’s, 328 and 2,422 for the two initialize bodies. Call it ~66 KB per flight worst case, times 17 flights to date, in a gitignored directory. Under two megabytes for the whole history. That is small enough that it stops being an argument and becomes a decision.

CAR F — the lane-scope amendment

foo_files.py currently carries a law that this compile’s own receipt falsifies. It reads that mcp.py --check is structurally incapable of printing GREEN in the compile lane. The receipt sitting three sections above says otherwise, from the compile lane, at exit 0.

The property was never the lane’s. It was the credential’s: a 300-second bearer cannot survive the gap between a human ignition and a compile, and a static pre-shared token has no gap to survive. One specimen got generalized into a law, and the law has now been wrong in two consecutive compiles — PROTECTION-LAG POLARITY in its expensive direction, because a reader trusting the constitution over the source would believe a compile-lane GREEN impossible while three of them sit in the receipt directory.

The hostname is redacted in the amendment on purpose. foo_files.py is tracked and public, and m pushes it. The compile-lane substitution table rewrites the payload, never the file on disk, so writing irf.production.botify.com into the constitution would publish an internal production hostname to GitHub. The receipt is cited with the identifying field elided and every other field intact.

# ago, and 694 minus 300 is 394. STANDING CONSEQUENCE, SCOPED TO THE CREDENTIAL
# (amended 2026-08-29, receipt-falsified): the limit belongs to the CREDENTIAL's

[[[REPLACE]]]

The replacement deliberately does not reproduce the phrase it retires, so the straddle probe below reads a clean two-way flip instead of finding its own epitaph — the failure THE EPITAPH COUNTER earmark banks two screens further down the same file.

Ignition: none required. foo_files.py is read fresh by the compiler at call time, and the probe is an rg over the file on disk.

1. PROBES

rg -c 'STRUCTURALLY INCAPABLE of printing GREEN' foo_files.py; echo "old_claim_exit=$?"; rg -c 'SCOPED TO THE CREDENTIAL' foo_files.py; echo "new_claim_exit=$?"
n=$(ls browser_cache/mcp/*/*.json 2>/dev/null | wc -l); echo "receipts=$n"; jq -r '[.verb, (.dclass // "null"), (.tool // "-")] | @tsv' browser_cache/mcp/*/*.json 2>/dev/null | sort | uniq -c | sort -rn

Probe 1 is CAR F’s straddle and it flips both ways. Before the car: 1 then old_claim_exit=0, then no output and new_claim_exit=1. After: the mirror image. Two patterns in opposite directions, so neither the count nor the exit code alone can be misread as unchanged.

Probe 2 is the CAR E gate, and it is the census I argued above rather than my arithmetic about it. It reads every FDR receipt on the box and reports verb, declared class, and tool as a frequency table — bounded to a handful of lines regardless of how many receipts exist. receipts=N first, so an empty glob is legible rather than silent. What I expect: one tools/call row, everything else check or tools/list, and null in the dclass column across the board. If a non-null dclass appears, a specimen already exists and CAR E gets cheaper immediately.

Both probes are read-only and open no socket.

The three probes from this turn are retired. The resolver probe flipped cleanly and would now print False forever; the server-two check prints the identical GREEN line every run; the FDR projection reads a receipt whose shape is stable. All three are RETIRE-THE-CANARY shaped. The resolver probe in particular belongs in tests/ beside test_apply_airlock.py, alongside the token_path_for agreement guard and the make_client grammar guard already retired there in spirit — three orphaned invariants now, which is enough to justify a small tests/test_mcp_credentials.py ride whenever you want it.

2. NEXT CONTEXT

! rg -c 'STRUCTURALLY INCAPABLE of printing GREEN' foo_files.py; echo "old_claim_exit=$?"; rg -c 'SCOPED TO THE CREDENTIAL' foo_files.py; echo "new_claim_exit=$?"
! n=$(ls browser_cache/mcp/*/*.json 2>/dev/null | wc -l); echo "receipts=$n"; jq -r '[.verb, (.dclass // "null"), (.tool // "-")] | @tsv' browser_cache/mcp/*/*.json 2>/dev/null | sort | uniq -c | sort -rn
scripts/connectors/mcp.py

One file. foo_files.py comes out — it is 74k tokens, CAR F lands this turn, and probe 1 reads it from disk rather than from context. So does the rolling pin (61k), prompt_foo.py (42k), flake.nix (28k), GLOSSARY.md (7.5k), apply.py, .gitattributes, .gitignore, requirements.in, __init__.py and pyproject.toml. This compile is 309k tokens for a two-block edit across two files; the next one should be under 15k.

The two stray 3 prefixes are still on the foo_cartridge / foo_replay lines — the DE-PREFIXED hint caught both again, sixth consecutive compile. They vanish with the trim above, so no separate action needed.

3. PATCHES

CAR F above, one block, one file. Choreography: patch, app, d, m, then blast.

Ignition: none required.

CAR E is held, with its prerequisite named rather than implied: one tools/call receipt carrying an explicit --dclass, so the adjudicator has a specimen on a branch it can pass. Probe 2 is the reading that confirms or refutes my census.

Not licensed for separate reasons, all unchanged: client-id portability across resources stays INFERRED and this vendor cannot settle it, because server two runs no authorization server at all. The discover() append-versus-insert question stays OPEN — neither URL returned 200. The netloc escape defends a file that will never be written. Nothing new arrived to move any of them.

4. PROMPT

CAR F landed (or did not — read the receipts, not my memory). Two probes are
echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each CHANGES:

1. Probe 1, both halves. old_claim_exit=1 with no output AND new_claim_exit=0
   with a 1 is the car landed and the falsified law is gone. The reverse means
   it did not land — say so before ruling on anything else. Any reading where
   BOTH patterns match is the epitaph failure: the amendment quoted the phrase
   it retired, and I want that named rather than explained away.

2. Probe 2. Report receipts=N, then the frequency table verbatim. Answer two
   things from it: how many receipts have verb "tools/call" (those are the only
   replayable ones), and how many carry a non-null dclass (those are the only
   adjudicable ones). If the second number is zero, say plainly that the D0
   adjudicator has no specimen and that building it now would ship a verdict
   machine whose pass branch cannot be witnessed.

Then, in this order:

FIRST, if probe 2 shows zero declared receipts, give me the ACTUATOR — not a
patch — that mints one. A tools/call against a named tool on a named server
with --dclass declared. Pick the tool from what tools/list actually returns and
argue why you expect it to be D0 rather than D1; if you cannot name a plausible
D0 tool on either server, say that D0 may not exist here and that the
adjudicator's first honest form is D1-only, which needs the body store first.
Name what the receipt should contain on success so I can rule on it next turn.

SECOND, emit AT MOST ONE car:

CAR E — THE D0 ADJUDICATOR. Only if a declared receipt now exists. A replay
  subcommand reading server + verb + tool + args_raw + auth_env + auth_scheme,
  re-issuing, hashing, and ruling: D0 match or falsified; D1 "drift, body not
  retained" with no characterisation attempted; D2 "new observation at <ts>"
  and no ruling at all. Say what it does with a receipt whose verb is "check"
  or "tools/list" — those carry no tool and no args_raw, and refusing them by
  name is better than crashing on a None. Say how the credential is
  re-resolved at replay time and confirm no secret is read from the receipt.
  Do NOT build the body store in the same car.

CAR G — THE BODY STORE. Only if you argue D0 does not exist on these servers,
  making D1 the only useful verdict. Persist response bodies beside the
  receipts under a gitignored path, keyed by body_sha256 so identical bodies
  cost one copy. Cite the size estimate from the receipts. Say what it does to
  the four-tuple's "the token value NEVER touches disk" invariant, because a
  response body is not a credential but an initialize response might carry
  session material.

If probe 1 shows the car did not land, emit NOTHING and tell me which half of
the two-way flip failed.

Do NOT touch wallet.py. Do NOT patch obtain_client_id. Do NOT write the
registry file. Do NOT put the second server's hostname into any tracked file;
foo_files.py is public and m pushes it.

For anything you emit, name the ignition or state "no ignition required", and
give me the straddle probe that reads differently after it lands.

5. EXTERNAL DELIVERABLES

None this turn. Two housekeeping notes: deleteme.txt is now ignored and the hazard is closed, though .gitignore carries the same line nine times in the temp block — harmless to git, but it reads as a slipped macro and one line would do. And scrub irf.production.botify.com still stands before this thread becomes an article; the amendment above keeps the hostname out of the repo, but it is throughout the transcript.

MikeLev.in: This can just go on forever and I don’t understand a word you say. I’m going to finish this train and then switch to a different model to see if they can explain this to me simply.

4: Prompt: CAR F landed (or did not — read the receipts, not my memory). Two probes are echoed into this compile. Name the LANE for every reading.

Rule first, one line each, and say what each CHANGES:

Probe 1, both halves. old_claim_exit=1 with no output AND new_claim_exit=0 with a 1 is the car landed and the falsified law is gone. The reverse means it did not land — say so before ruling on anything else. Any reading where BOTH patterns match is the epitaph failure: the amendment quoted the phrase it retired, and I want that named rather than explained away.
Probe 2. Report receipts=N, then the frequency table verbatim. Answer two things from it: how many receipts have verb “tools/call” (those are the only replayable ones), and how many carry a non-null dclass (those are the only adjudicable ones). If the second number is zero, say plainly that the D0 adjudicator has no specimen and that building it now would ship a verdict machine whose pass branch cannot be witnessed.

Then, in this order:

FIRST, if probe 2 shows zero declared receipts, give me the ACTUATOR — not a patch — that mints one. A tools/call against a named tool on a named server with –dclass declared. Pick the tool from what tools/list actually returns and argue why you expect it to be D0 rather than D1; if you cannot name a plausible D0 tool on either server, say that D0 may not exist here and that the adjudicator’s first honest form is D1-only, which needs the body store first. Name what the receipt should contain on success so I can rule on it next turn.

SECOND, emit AT MOST ONE car:

CAR E — THE D0 ADJUDICATOR. Only if a declared receipt now exists. A replay subcommand reading server + verb + tool + args_raw + auth_env + auth_scheme, re-issuing, hashing, and ruling: D0 match or falsified; D1 “drift, body not retained” with no characterisation attempted; D2 “new observation at " and no ruling at all. Say what it does with a receipt whose verb is "check" or "tools/list" — those carry no tool and no args_raw, and refusing them by name is better than crashing on a None. Say how the credential is re-resolved at replay time and confirm no secret is read from the receipt. Do NOT build the body store in the same car.

CAR G — THE BODY STORE. Only if you argue D0 does not exist on these servers, making D1 the only useful verdict. Persist response bodies beside the receipts under a gitignored path, keyed by body_sha256 so identical bodies cost one copy. Cite the size estimate from the receipts. Say what it does to the four-tuple’s “the token value NEVER touches disk” invariant, because a response body is not a credential but an initialize response might carry session material.

If probe 1 shows the car did not land, emit NOTHING and tell me which half of the two-way flip failed.

Do NOT touch wallet.py. Do NOT patch obtain_client_id. Do NOT write the registry file. Do NOT put the second server’s hostname into any tracked file; foo_files.py is public and m pushes it.

For anything you emit, name the ignition or state “no ignition required”, and give me the straddle probe that reads differently after it lands.

5: Deliverables: None this turn.

Hey ChatGPT, I am totally fatigued here and it feels like I’m just spinning my wheels. I’ve got to close this article and re-orient myself trying to actually directly use both of those MCP servers through terminal which I think I’m in a good position to do, but I need clarification. I know there’s unknowns but if I was supposed to be doing more during my interaction with Opus like attempting to use the MCP servers or do the warming or check if the Bearer tokens were in place or whatever to actually do the work it is not immediately obvious. Can you just generally enlighten me Shoshin-style? Barney style? How to make a peanut butter sandwich instructions? There’s secret-keeping acrobatics here too that I need explained. Just generally bring me up to speed on what happened over the 5000+ lines of this article please and thank you.

ChatGPT 5.6 Sol Pro Extended: Context verified. I followed the artifact’s routing rule and treated its final Prompt as the live request.

You succeeded—and then the engineering process failed to stop

You now have a terminal client that can communicate directly with two remote MCP servers. This is no longer hypothetical:

The current receipt bank contains 20 MCP flights.
Seventeen are connection/handshake checks.
Three are actual tools/call invocations of list_projects, explicitly classified as D1.
The original vendor receipt records list_projects being called against the OAuth MCP server.

So you were not merely preparing to use MCP. You used MCP.

The article continued because every successful experiment exposed another possible hardening improvement:

“Now that it connects, should we improve credential paths? Now that paths work, should we support another auth scheme? Now that that works, should we fix replay? Now should we retain bodies? Now should we build a registry?”

Those are reasonable future engineering projects. They are not prerequisites for terminal MCP use.

The missing ingredient was a stop rule:

Stop when you can authenticate, list tools, call a tool, obtain a result, and avoid sending one server’s credential to another.

You reached that point.

The Barney-style model

Think of an MCP server as a workshop with a locked front door and a rack of tools inside.

Get the right key.
Test the front door.
Ask for the tool menu.
Choose a tool.
Supply that tool’s arguments.
Receive the result.
Keep the receipt.
Stop.

Your two Python programs have very different jobs:

mcp_warm.py     gets or refreshes an OAuth key
mcp.py          uses a key to talk MCP

And mcp.py has four modes:

python scripts/connectors/mcp.py
    Show local credential state. No network connection.

python scripts/connectors/mcp.py <SERVER> --check
    Test authentication, MCP initialization, and tools/list.

python scripts/connectors/mcp.py <SERVER>
    Show the server's tool menu.

python scripts/connectors/mcp.py <SERVER> <TOOL> '<JSON>'
    Actually call a tool and do work.

That last form is where the work happens. The client parses your JSON, initializes the MCP session, sends a tools/call, prints the result, and writes a flight-data receipt.

Why it still did not feel obvious

There is a real usability gap in the current client: its menu prints only each tool’s name and the first 80 characters of its description. It receives the MCP tool’s inputSchema, but does not display it. Therefore, it can tell you:

list_projects  List projects available to the current user...

but may not tell you the exact JSON object that another tool expects.

That is one reason you felt, “Okay, but where do I actually do the work?”

The answer is still mcp.py <server> <tool> '<json>'; the current menu simply does not provide as much argument guidance as it should.

Two doors, two entirely different locks

The central discovery was that “Botify MCP” is not one authentication system. It is two MCP servers operated under the same vendor umbrella, each using a different credential kind.

	OAuth MCP server	Second MCP server
Credential	OAuth access token	Static API token
Header	`Authorization: Bearer …`	`Authorization: Token …`
Preparation	`mcp_warm.py --refresh`	None
Browser needed	Initially, or if refresh fails	No
Access-token clock	300 seconds	No demonstrated short clock
Credential source	Protected local JSON file	`BOTIFY_API_TOKEN` environment variable
Latest observed check	`session=no`, 42 tools	`session=yes`, 56 tools

The first server was refreshed and checked successfully in one command, producing a fresh 300-second token followed by mcp GREEN, 42 tools, and no MCP session ID.

The second server accepted the static token only when the header grammar was Token, not Bearer. It then completed initialization and tool discovery with 56 tools and an MCP session ID.

session=no does not mean the first server failed. MCP session IDs are optional:

The first server does not issue one.
The second server issues one during initialize.
Your client sends it back on the following requests.

Both behaviors are valid. The second server’s receipt shows the handoff clearly: return the ID on initialization, then send it on notifications/initialized and tools/list.

The OAuth server, explained as a coat-check counter

Here is what mcp_warm.py is doing.

Full browser warm

Imagine going to a secure coat-check counter:

Your terminal asks the MCP resource, “Who handles identity for you?”
It discovers the authorization server.
It registers a temporary public OAuth client when needed.
It opens your ordinary browser.
You authenticate in the browser.
The browser returns a one-time authorization code to a tiny, temporary listener on 127.0.0.1.
The terminal exchanges that code for:
- a short-lived access token;
- a longer-lived refresh token.
The token record is written to a local file with Unix mode 0600.

The browser is where your human login happens. The terminal never needs your browser password.

The localhost callback does not receive the final bearer token. It receives a short-lived code that must also match the PKCE proof held by the terminal. state protects against a mismatched or injected callback, while the OAuth resource value ties the resulting credential to the intended MCP resource.

Refresh

The access token lives for only 300 seconds. That sounds absurd until you remember that the refresh token is the durable refill card.

Once the initial browser flow has succeeded, ordinary use should be:

python scripts/connectors/mcp_warm.py --refresh \
  && python scripts/connectors/mcp.py https://mcp.botify.com --check

--refresh:

does not open a browser;
uses the stored refresh token;
obtains a new five-minute access token;
rewrites the protected token record;
immediately hands control to mcp.py.

That is the terminal habit. You do not warm it in the morning and hope the token remains alive all day. You refresh immediately before the operation.

A full browser warm is needed only when:

no token record exists;
no refresh token exists;
the refresh token has been revoked or expired;
the authorization server otherwise refuses refresh.

Because refresh works, repeated full browser warms are unnecessary.

The second server is much simpler

The second server does not use that OAuth ceremony.

Its vendor configuration said, in effect:

Take the existing API token.
Send it as:

Authorization: Token <value>

That means:

no authorization-server discovery;
no browser;
no localhost callback;
no OAuth client registration;
no PKCE;
no refresh token;
no five-minute OAuth clock.

The attempt to run mcp_warm.py against it failed because the warmer was knocking on a non-OAuth door and asking for OAuth metadata that the server does not provide.

The supplied npx mcp-remote configuration was a bridge for applications that speak MCP through a local stdio subprocess. Your mcp.py already speaks Streamable HTTP directly, so the bridge is unnecessary in your terminal workflow.

This was the most important conceptual finding in the whole article:

Credential type is a property of a particular server, not of the vendor name.

One company can operate:

one server expecting an OAuth Bearer;
another expecting a static Token;
perhaps another with no authentication;
perhaps another with an entirely different mechanism.

What the thousands of lines actually accomplished

Stripped of the train cars, lane language, self-prompts, diffs, and repeated receipts, the story is manageable.

1. You proved terminal OAuth

mcp_warm.py successfully completed browser authentication and wrote a protected OAuth record. mcp.py then talked MCP directly over HTTP.

2. You proved the no-browser daily driver

The stored refresh token successfully produced a new five-minute access token, followed immediately by a green MCP check.

3. Credentials were separated by server

Originally there was one historical filename:

~/.config/pipulate/mcp_botify_token.json

That does not scale safely to arbitrary servers.

The connector now derives a path from the resource URL:

~/.config/pipulate/mcp/<host>[__path].json

This gives each OAuth resource its own credential home.

4. The second server exposed a different lock

Trying the OAuth warmer against it failed. Direct probes established:

anonymous request: rejected;
Bearer: rejected;
Token: accepted.

5. `mcp.py` learned per-server header grammar

The client gained:

--auth-scheme Bearer
--auth-scheme Token

Bearer remains the default, preserving the first server.

The second server is selected explicitly with:

--auth-scheme Token --token-env BOTIFY_API_TOKEN

6. A real cross-server credential hazard was found

The compatibility code initially said:

“If the new server-specific file does not exist, use the old OAuth file.”

Unfortunately, that fallback originally applied to every server. In the wrong invocation, it could have offered server one’s OAuth bearer to server two.

The fix now opens the legacy record, reads the resource for which it was minted, and uses it only when that resource matches the requested server. Otherwise it loudly declines and continues down the credential ladder.

That was an important security repair.

7. The flight recorder became more truthful

Receipts now include the authentication scheme as well as the credential source name. This matters because:

no credential       -> 403
wrong Bearer scheme -> 403
correct Token       -> 200

Without the scheme field, the first two failed flights could look indistinguishable.

8. The conversation wandered into optional infrastructure

After terminal MCP was already operational, Opus began considering:

replaying old calls;
adjudicating D0/D1/D2 results;
retaining complete response bodies;
building a server registry;
adding wallet integration;
reusing a pinned OAuth client ID;
creating permanent tests for retired probes.

These are not necessary to call MCP tools. The proposed replay adjudicator was explicitly held because the receipt corpus did not contain a useful D0 specimen; response-body storage was identified as a later prerequisite for explaining D1 drift.

That is where the train stopped serving your immediate goal.

Translating the strange vocabulary

Opus term	Ordinary meaning
Car	One proposed patch or tightly scoped change
Probe	A command that observes something without changing it
Operator lane	You ran the command manually
Compile lane	Prompt Fu ran the command automatically during the next compile
Straddle	Run the same probe before and after a patch
GREEN / RED	Passed / failed
Ignition	An extra action needed before patched code takes effect
FDR	A JSON flight-data receipt describing an MCP request
Constitution	The accumulated engineering rules and comments in `foo_files.py`
D0	Same inputs should produce identical bytes forever
D1	A stable read that changes when server-side state changes
D2	An inherently time-varying observation

Your three list_projects calls were D1 because a project list is stable enough to reproduce for a while, but it can change when projects are added, removed, or permissions change. The classes are just receipt labels for future replay logic. They do not affect how the server executes the tool. The current definitions are embedded directly in the client.

The secret-keeping acrobatics

There are really three separate privacy systems here. Mixing them together made the story sound more mystical than it is.

Layer 1: runtime credentials

OAuth server

The OAuth access token and refresh token live in a protected JSON file. Mode 0600 means only your Unix user should be able to read or write it.

The current file is still the historical pre-derivation file. That is safe now because the compatibility fallback checks the record’s resource. The next full browser warm will write the new server-derived path. You may then manually remove the old file, but there is no emergency requiring you to do that today.

Static-token server

mcp.py reads the value of BOTIFY_API_TOKEN from the environment and constructs:

Authorization: Token <value>

The source proves that the variable was present. It does not establish where you originally stored or loaded that environment variable, so that part should not be guessed.

Important rule

Never paste the literal token into the command:

# Bad: token enters shell history and process arguments
--token-env abc123actualsecret

--token-env expects the name of an environment variable:

# Correct
--token-env BOTIFY_API_TOKEN

Layer 2: MCP receipts

The flight recorder stores useful reconstruction information:

server URL;
MCP verb;
tool name;
raw JSON arguments;
D0/D1/D2 declaration;
credential source name;
authentication scheme;
HTTP statuses;
sizes and hashes;
protocol/session information.

It does not place the Authorization token value into the receipt.

But that does not mean a raw receipt is automatically publication-safe.

Two important catches:

Tool arguments are stored byte-for-byte. If you place a password, token, customer secret, or private content inside <JSON_ARGUMENTS>, the receipt will retain it.
Response headers and MCP session IDs may be sensitive. The article’s safer projections intentionally omitted raw response headers and reduced session IDs to booleans before compiling them.

So the practical rule is:

Authorization credentials are deliberately excluded, but arbitrary tool arguments and response metadata still require judgment.

The recorder also retains only a body hash and size, not the complete response body. That is why it can say “same response” or “different response” but cannot yet explain exactly what changed.

Layer 3: publication sanitization

[[[private]]], the scrubber, and the sanitizer are about preventing internal hosts and client information from entering the published article. They are not part of MCP authentication and they are not encryption.

The temporary file containing the second server’s configuration was eventually ignored, closing the accidental-commit hazard. The transcript still contains the private hostname, so the existing scrub operation remains required before publication.

That is why I have used <SECOND_MCP_URL> rather than repeating it here.

Should you have been doing more while interacting with Opus?

No—not for the goal you stated.

In this workflow:

Opus      = navigator, reviewer, and patch author
You       = the hand operating the local terminal
mcp.py    = the actual MCP client
Server    = the remote actuator/tool provider
Receipts  = the evidence returned to the next model turn

Opus was not secretly sitting inside your local terminal using the remote servers. It was reviewing the code and telling you what to run. You ran the commands and fed the resulting evidence into the next compile.

You also did not need to keep “warming” tokens during every conversational turn:

Refresh the OAuth server immediately before an operation.
Do not warm the static-token server at all.
Do not keep either server artificially busy.
Do not build replay, body storage, a registry, or wallet integration merely to perform a normal tool call.

There is one narrow evidentiary nuance:

The first server definitely has a historical, explicit tools/call list_projects receipt.
The second server definitely completed authenticated initialization and tools/list.
The final census groups calls by verb/class/tool but not by server, so it does not prove from that table alone that one of the three list_projects calls targeted server two.

Therefore, a single harmless read-only domain-tool call against the second server would provide perfect end-to-end symmetry. It is optional. The source does not expose a safe tool name and argument schema for that server, so inventing one would be irresponsible.

How to use the two servers now

First, inspect local state

python scripts/connectors/mcp.py

That identity walk opens no network connection and prints no token value.

OAuth server: test it

python scripts/connectors/mcp_warm.py --refresh \
  && python scripts/connectors/mcp.py https://mcp.botify.com --check

Expected shape:

gate6 GREEN ...
mcp GREEN ... protocol=2025-06-18 session=no tools=<number> ...

The tool count may change. That is ordinary D1 drift, not failure.

python scripts/connectors/mcp_warm.py --refresh \
  && python scripts/connectors/mcp.py https://mcp.botify.com -n 50

OAuth server: do actual work

python scripts/connectors/mcp_warm.py --refresh \
  && python scripts/connectors/mcp.py \
       https://mcp.botify.com \
       '<TOOL_NAME>' \
       '<JSON_ARGUMENTS>' \
       --dclass D1

The JSON must be valid JSON, usually an object:

'{}'
'{"project_slug":"example"}'

Do not guess the argument names. Obtain them from the server’s documentation, a known example, or a future schema-display improvement.

Static-token server: test it

Use your private URL locally:

python scripts/connectors/mcp.py \
  '<SECOND_MCP_URL>' \
  --check \
  --auth-scheme Token \
  --token-env BOTIFY_API_TOKEN

python scripts/connectors/mcp.py \
  '<SECOND_MCP_URL>' \
  -n 50 \
  --auth-scheme Token \
  --token-env BOTIFY_API_TOKEN

Static-token server: do actual work

python scripts/connectors/mcp.py \
  '<SECOND_MCP_URL>' \
  '<TOOL_NAME>' \
  '<JSON_ARGUMENTS>' \
  --dclass D1 \
  --auth-scheme Token \
  --token-env BOTIFY_API_TOKEN

On success, mcp.py prints:

the four-tuple receipt;
the returned JSON, capped by --max-bytes;
the path of the JSON FDR receipt.

That is the whole working loop.

What remains unfinished—but is not blocking you

These are convenience or observability projects:

A nickname registry so you can type mcp render instead of the full URL and flags.
Showing each tool’s inputSchema.
Automatically obtaining the auth scheme from per-server configuration.
Wallet-board integration.
Reusing a pinned OAuth client registration on future full browser warms.
Replaying a receipt automatically.
Retaining full response bodies and explaining D1 drift.
Native stdio transport for local subprocess MCP servers.
Permanent unit tests for the credential-path and auth-scheme invariants.

None is required for the terminal habit you asked for.

The most valuable future convenience feature would probably be tool schema display, not replay adjudication. The largest source of day-to-day friction now is not transport or authentication; it is knowing what JSON a selected tool expects.

Your stop sign

You may close the article with this verdict:

Terminal MCP is operational.

Server one:
- OAuth browser warm works.
- Refresh without a browser works.
- Check and tools/list work.
- A real list_projects tools/call is witnessed.

Server two:
- Static Token authentication works.
- Check and tools/list work.
- MCP session handling works.

Shared client:
- Supports Bearer and Token grammars.
- Keeps credentials scoped to their intended server.
- Records calls without recording Authorization token values.

The fresh receipt census and final amendment are already present: the obsolete “compile lane can never be green” claim is gone, and the corpus contains three declared D1 tool calls.

That is enough. Stop the train.

1. PROBES

These are orientation readings only. They do not gate another patch.

python scripts/connectors/mcp.py
n=$(ls browser_cache/mcp/*/*.json 2>/dev/null | wc -l); echo "receipts=$n"; jq -r '[.verb, (.dclass // "null"), (.tool // "-")] | @tsv' browser_cache/mcp/*/*.json 2>/dev/null | sort | uniq -c | sort -rn

2. NEXT CONTEXT

No next MCP compile is needed. Should you deliberately open a later MCP turn, the minimal adhoc.txt context is:

! python scripts/connectors/mcp.py
! n=$(ls browser_cache/mcp/*/*.json 2>/dev/null | wc -l); echo "receipts=$n"; jq -r '[.verb, (.dclass // "null"), (.tool // "-")] | @tsv' browser_cache/mcp/*/*.json 2>/dev/null | sort | uniq -c | sort -rn
scripts/connectors/mcp.py
scripts/connectors/mcp_warm.py

3. PATCHES

No repo patches required.

No ignition required.

4. PROMPT

Terminal MCP is operational. Treat replay, body storage, wallet integration,
server registries, pinned-client reuse, and further constitution work as out
of scope.

Help only with the concrete MCP operation I name. Do not propose another patch
train unless an actual terminal call fails at a named gate. When a tool call is
requested, first identify its real input schema; do not invent JSON arguments.

5. EXTERNAL DELIVERABLES

Before publishing the article, run the existing scrub for the private second-server hostname. Do not publish raw MCP receipts without reviewing args_raw, response headers, and session fields. No other deliverable is required.

Gemini 3.7 Flash Extended: Closing Summary: The Stop Sign

The marathon is over because the core requirement is completely solved. You don’t need a massive registry file, an automated replay engine, or a wallet database to use MCP from your command line.

What is working today:

OAuth Loop (Server 1): One-liner chaining (mcp_warm.py --refresh && mcp.py <server> <tool> '<json>') handles the 5-minute access token lifespan painlessly.
Static API Headers (Server 2): Native support via --auth-scheme Token --token-env BOTIFY_API_TOKEN connects directly over Streamable HTTP.
Derived Credential Isolation: Each endpoint writes to its own isolated, URL-derived JSON path, preventing accidental token contamination.
Audit Logging: Every check and tool call writes a structured receipt recording HTTP status, latency, response byte counts, and hash fingerprints.

The Practical Cheat Sheet

# 1. OAuth Server: Refresh token & inspect tools
python scripts/connectors/mcp_warm.py --refresh && \
  python scripts/connectors/mcp.py https://mcp.botify.com -n 50

# 2. OAuth Server: Call a tool
python scripts/connectors/mcp_warm.py --refresh && \
  python scripts/connectors/mcp.py https://mcp.botify.com list_projects '{}' --dclass D1

# 3. Static Token Server: Call a tool
python scripts/connectors/mcp.py <SECOND_MCP_URL> <TOOL_NAME> '<JSON>' \
  --auth-scheme Token --token-env BOTIFY_API_TOKEN --dclass D1

The engineering temptation was to keep building meta-infrastructure—replay adjudicators, full body stores, and dynamic registries. But the doors are unlocked, the keys fit, and the tools run. It’s time to stop hardening the plumbing and start doing the work.

Book Analysis

Ai Editorial Take

What surprised me most about this entry is how quickly an exploratory debugging session transformed into a profound lesson on API contract design. Developers often fall into the trap of assuming that a single vendor uses a uniform authentication model across all their services. By hitting a hard wall with a second endpoint, this piece exposes the danger of vendor-level assumptions and offers a masterclass in building resilient, single-responsibility tooling that handles per-server realities with elegance.

Title Brainstorm

Title Option: Terminal-Native MCP Without the Bloat: Connecting Directly in the Age of AI
- Filename: terminal-native-mcp-without-the-bloat
- Rationale: Directly highlights the core technical achievement and utility of the article, appealing to developers seeking lightweight alternatives to bulky tools.
Title Option: Demystifying Model Context Protocol from the Unix Terminal
- Filename: demystifying-mcp-from-unix-terminal
- Rationale: Emphasizes the educational and architectural aspect of breaking down complex API integrations into standard command-line components.
Title Option: The Per-Server Authentication Reality: Building a Lean Terminal MCP Client
- Filename: per-server-authentication-reality-lean-mcp-client
- Rationale: Focuses on the critical discovery that security schemes vary per endpoint rather than per brand, offering a strong architectural lesson.

Content Potential And Polish

Core Strengths:
- Provides concrete, runnable code patterns and command receipts rather than abstract architectural theory.
- Accurately diagnoses the friction between short-lived OAuth tokens and human-speed development loops.
- Demonstrates excellent iterative debugging, turning unexpected API behavior into robust design principles like derived credential paths.
Suggestions For Polish:
- Condense the interactive prompt-and-response history to maintain a steady narrative flow suitable for a published book chapter.
- Ensure all specific internal production URLs or sensitive identifiers are scrubbed before final publication.
- Highlight the distinction between streamable HTTP transport and local stdio bridges more explicitly for readers new to MCP.

Next Step Prompts
