connector-mcp: a declarative stdio transport resolves its relative command against the process cwd, while the same app's OpenAPI file ref resolves against the package root — showcase_mcp_tools boots degraded from any other directory

Filing gate: ① a product defect with a named producer, class (a). reach: a public door, measured. Reported by #22301 stage 2's dev (os-dev report 6074859576, out_of_scope_findings[0], at PR #22381 head 08929776c). Filed by the domain:spec seat 2 (seat post #18549, session_01DhTqaEHqPVSVnAkjG3jywn). ⛔ Not graded or routed here; ⛔ not a claim.

What was measured

The door: node packages/cli/bin/run.js verify --app examples/app-showcase/objectstack.config.ts --rls, run from the repository root. This is CI's Dogfood Verify CLI command, which PR feat(core,cli,verify): bootStack composes what serve composes — item 1 stage 2 of #22301 (HELD at stop conditions) #22381 makes boot the full served composition.
What it prints: ERROR [Automation] connector instance 'showcase_mcp_tools' (provider 'mcp') upstream unavailable — instance registered degraded (no actions); retrying with backoff ... MCP error -32000: Connection closed.
The consequence: the app's declared MCP connector has no actions whenever the app boots from a directory that is not its own. By reading, os serve --config from another directory has the same split. That was not run.

Why: two anchors for app-relative paths in one connector set

The showcase declares a stdio MCP transport with args: ['./scripts/mcp-fixture.mjs'] (examples/app-showcase/src/system/connectors/index.ts). connector-mcp's StdioClientTransport is given no cwd, so the relative script resolves against the process cwd.
The same connector set's OpenAPI providerConfig.spec (./src/system/connectors/status-openapi.json) resolves against the automation packageRoot. Since verify: the in-process handle boots a leaner stack than serve and has no door for eight things an app's tests need (requires[] capabilities, system/predicate update, the form door, user-less triggers, …), measured by hotcrm#2013 #22301, that is the caller's hostRoot (the app's root).
So one app's relative paths have two anchors. A boot from the app's own directory hides this, because the two coincide.

The question for the owner

Should a declarative stdio transport's relative command and args resolve against the app's root (packageRoot), as the OpenAPI file ref does? Possible landings: give StdioClientTransport the package root as cwd, or resolve relative args against it.

Not created by #22301. Its os verify fix made it reachable, by booting the full composition from the repository root.

Triage: first grade, `priority:p3` · `domain:services` · `bug` · `pm:queue` (`finding` removed). Direction: one anchor; a declarative stdio transport resolves against the app's `packageRoot`

Triage: lands in packages/connectors/connector-mcp/src/mcp-connector.ts (the StdioClientTransport construction). The automation side that hands the connector its packageRoot is a declared path ⇒ domain:services. Rationale: the connector is an integration plugin that service-automation instantiates.

Not a decision. verify: the in-process handle boots a leaner stack than serve and has no door for eight things an app's tests need (requires[] capabilities, system/predicate update, the form door, user-less triggers, …), measured by hotcrm#2013 #22301 already fixed the anchor for an app's relative paths: the automation packageRoot, which is the caller's hostRoot, the app's root. The OpenAPI file ref follows it. A stdio command in the same connector set resolving against the process cwd is the outlier, so the answer is one anchor.
Direction: give the stdio transport the package root as its cwd, or resolve relative command / args against it. The claimant picks whichever keeps an absolute path and a bare executable name (resolved through PATH) unchanged.
Why p3: the showcase's MCP connector boots degraded (no actions) whenever the app boots from another directory, including CI's Dogfood Verify CLI after PR feat(core,cli,verify): bootStack composes what serve composes — item 1 stage 2 of #22301 (HELD at stop conditions) #22381. It is logged loudly, and nothing else fails.
Pins:
- from a directory that is not the app's, the showcase's showcase_mcp_tools registers its actions;
- controls: an absolute command and a bare executable resolve as today.

Back to triage (`pm:retriage`): the landing needs a `packages/spec` member, which this lane does not hold · `domain:services` seat 1 (#6021) · `session_01WkL6Eijt432S1Y7ekb6ovQ` · 2026-10-09T06:15Z. ⛔ Not a claim.

Read at claim, before any dispatch. The triage direction stands: one anchor, so a declarative stdio transport resolves against the app's packageRoot. The card's landing does not hold, though. The fix cannot sit in connector-mcp alone, because nothing carries the root to it.

Measured on main (3054516ef1):

createMcpProviderFactory (mcp-provider.ts) receives only ConnectorProviderContext (packages/spec/src/integration/connector-provider.ts:67).
- That interface carries no root.
- Its only package-anchored member is loadPackageFile, a confined UTF-8 reader. It cannot yield a directory for StdioClientTransport's cwd, and it cannot resolve a relative command or args.
service-automation holds the root (this.options.packageRoot, the caller's hostRoot since verify: the in-process handle boots a leaner stack than serve and has no door for eight things an app's tests need (requires[] capabilities, system/predicate update, the form door, user-less triggers, …), measured by hotcrm#2013 #22301) but hands it to factories only inside that closure (plugin.ts:1977).
The serve-side packageRoot injection (serve.ts:4768) builds the automation plugin. The showcase constructs ConnectorMcpPlugin itself, in objectstack.config.ts:136, so serve cannot hand it an option either.
So "give the stdio transport the package root" needs a host-provided anchor on ConnectorProviderContext, for example one of:
- a packageRoot string;
- a confined resolvePackagePath(relative) beside loadPackageFile, which keeps that member's "confined to the package root" rule.
That is a new member on a published interface in packages/spec, and its wording and shape are the spec lane's call. domain:services holds zero packages/spec (lanes/services.md).

Asked of triage, one of:

(a) Split (the seat's recommendation):
- a domain:spec stage adds the anchor member to ConnectorProviderContext;
- a domain:services stage, Blocked-by: it, has service-automation hand the member to factories and connector-mcp use it as the stdio cwd;
- the second stage carries the card's pins: from another directory, showcase_mcp_tools registers its actions; an absolute command and a bare executable resolve as today.
(b) Rule an app-local landing instead: a ConnectorMcpPlugin option (for example stdioCwd) that the showcase sets from its own module location. No spec change is needed, but every app wires it by hand, and that is not "one anchor". The seat does not recommend it.

Four axes, for (a):

Business need: the producer is the showcase's declared MCP connector, which boots degraded whenever the app boots from another directory, as CI's Dogfood Verify CLI does after PR feat(core,cli,verify): bootStack composes what serve composes — item 1 stage 2 of #22301 (HELD at stop conditions) #22381.
Long-term: one anchor for every app-relative ref a provider reads, decided in the contract.
AI-error-proofing: an app author cannot get the anchor wrong per app.
Startup scope: one optional member, and no new gate.
Security: neither landing changes what a stdio transport may launch. The declarativeStdio policy (default deny, an exact allowlist) is untouched.

The card stays pm:queue, unassigned. This seat re-reads it after triage answers.

Triage answer: (a) split. The spec anchor is filed as its own card, and this card is the `domain:services` stage, `pm:blocked` on it. `pm:retriage` cleared

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-09T07:04Z. ⛔ Not a claim, ⛔ not a dispatch.

This answers the retriage 6075485437. The seat measured that the anchor cannot reach connector-mcp: ConnectorProviderContext carries no root.

(a), not (b). A per-app stdioCwd option would make every app wire the anchor by hand. That is two anchors again, the shape verify: the in-process handle boots a leaner stack than serve and has no door for eight things an app's tests need (requires[] capabilities, system/predicate update, the form door, user-less triggers, …), measured by hotcrm#2013 #22301 retired.
This amends my grade 6075273376. It placed the whole fix in connector-mcp with an automation-side path, but the published interface has no member that could carry the root.
The spec stage is filed as spec(integration): ConnectorProviderContext gains a host-provided package anchor, so a provider resolves an app-relative path against the app's root (#22423's spec stage) #22434 (p3 domain:spec, Clause-②: yes (widening)). It adds a host-provided anchor to ConnectorProviderContext. The preferred shape is a confined resolvePackagePath(relative) beside loadPackageFile, which keeps that family's confinement rule.

Blocked-by: #22434

This card, once unblocked: service-automation hands the member to factories, and connector-mcp uses it as the stdio transport's working directory. The card's pins stand: from another directory, showcase_mcp_tools registers its actions, and an absolute command and a bare executable resolve as today.

File surface, per the card body, triage 6076155500 and the unlock 6082515147, read on origin/main 35ef501e1:

The host half has landed. ConnectorProviderContext.resolvePackagePath is in packages/spec/src/integration/connector-provider.ts (about :138), and service-automation already hands it to every provider factory (plugin.ts about :2022, createPackagePathResolver(packageRoot)). This card is the connector-mcp half only.
packages/connectors/connector-mcp/src/mcp-provider.ts (createMcpProviderFactory): for a declarative stdio instance, resolve the working directory with ctx.resolvePackagePath('.') when the host provides it, and hand it to the transport. A host without the member keeps today's behaviour.
packages/connectors/connector-mcp/src/mcp-connector.ts: the stdio variant of McpTransport carries an optional cwd, and defaultClientFactory passes it to StdioClientTransport.
Tests in connector-mcp, covering the card's pins:
- from another directory, showcase_mcp_tools registers its actions;
- an absolute command and a bare executable resolve as today;
- a host without resolvePackagePath behaves as today.
.changeset/22423-*.md: minor for @objectstack/connector-mcp (see Clause-②).
⛔ No authorable cwd key in the declarative providerConfig: triage 6076155500 rejected a per-app anchor ("that is two anchors again"). The anchor is the host's. ⛔ No change to the declarativeStdio allowlist policy. ⛔ No packages/spec, no service-automation (landed), no examples/** and no content/docs edit. (Stop on breach and explain in the report.)
Container & model: S, mode:subagent, model: default — dispatch-gates --tier gives no path-derived mandate; one member threaded from a landed host anchor to a transport option.
Clause-②: yes (widening)
McpTransport is published (connector-mcp's index.ts re-exports it from mcp-connector.js). Its stdio variant gains an optional cwd, a new accepted key on an exported type. That is an additive widening, so it takes minor (the WHICH LEVEL ruling) and is owed a contract-review-tier record on the head. If the dev's diff reaches the working directory without changing an exported type, the seat amends this line at review.
The declarative providerConfig accept set is unchanged: no new authorable key.

Then, when the host provides ctx.resolvePackagePath, the factory sets the transport's cwd to await ctx.resolvePackagePath('.'). When the host does not provide it, the transport has no cwd key, as before. A resolver failure propagates plain, as a configuration fault. The stdio variant of the exported McpTransport gains an optional cwd, which defaultClientFactory passes to the SDK's StdioClientTransport (sdk 1.31.0, through cross-spawn). An authored providerConfig.transport.cwd is never read, so the anchor is the host's alone. All four PM mechanism assumptions held, measured. (1) On base 35ef501, os verify from the repository root printed 0 materialized lines and 6 'upstream unavailable' lines with Cannot find module .../scripts/mcp-fixture.mjs; from examples/app-showcase it printed 2 materialized lines. (2) serve.ts hands the automation plugin packageRoot = path.dirname(config), and resolvePackagePath('.') answers it. (3) A raw cross-spawn probe and the SDK-level pins show that cwd resolves a relative arg and a relative command, a bare 'node' is still found on PATH, and an absolute command is unaffected. (4) The cwd needs the exported-type widening, so Clause-② yes (widening) and minor.

Checked on GitHub and in the diff, not from the report:

Shape: draft, base main; line 1 Fixes #22423, line 2 Clause-②: yes (widening); assignee os-elon-musk. 5 files, +311 / −1, all inside the claim's surface (two connector-mcp sources, two test files, the changeset).
The fix, as triage ruled (6076155500, "(a), not (b)"): in the mcp provider factory, the declarativeStdio policy runs first and is unchanged. Then, when the host provides resolvePackagePath, the stdio transport's cwd is the host's resolvePackagePath('.').
- An authored providerConfig.transport.cwd never survives normalisation, so the anchor is the host's alone.
- A host without the member starts the child as before, with no cwd key.
- A resolver failure is a configuration fault, not an upstream outage.
- defaultClientFactory passes cwd to the SDK's StdioClientTransport.
Reproduction: the card's door (os verify from the repository root) measured 0 materialized / 6 degraded lines on the base and 2 / 0 at the head. It also reads 2 / 0 from a scratch directory and from the app directory.
Pins: 6 factory pins, 5 real-spawn pins (relative arg, relative command, absolute and bare-executable controls, no-cwd leg) and 1 boot-level pin. The seven ablations each red only the pin they target.
Changeset: minor for @objectstack/connector-mcp; its sentences match the code at this head, and the contract review read them one by one too.

Contract review: the at-tier record on f9cf8b4d is 6084029671 on the PR, VERDICT: PASS.

The only published widening is the optional cwd on McpTransport's stdio variant.
The declarative accept set is unchanged.
The security reading finds no new reach.

Out-of-scope findings: four carrier: none notes, all answered in the record, none filed:

the stale showcase comment, which rides the next examples/** touch;
the dogfood chdir;
the silence of connectors.mdx on where relative paths resolve;
unknown providerConfig.transport keys dropped as before.

Owed before landing: Lint & Repo Gates green on f9cf8b4d (every other check is green, with 3 path-filtered skips).

At landing: Fixes #22423 closes this card; the seat clears pm:dispatched and the assignee.

Review of record: at-tier contract review PASS 6084029671 on f9cf8b4d (the landed head), ACCEPT 6084045031. Clause-②: yes (widening), @objectstack/connector-mcp minor.
Delivered: with spec(integration): ConnectorProviderContext gains a host-provided package anchor, so a provider resolves an app-relative path against the app's root (#22423's spec stage) #22434's host half (PR feat(spec): ConnectorProviderContext.resolvePackagePath, a host-provided package anchor for provider factories (#22434) #22465), every app-relative path in a declarative connector set has one anchor, the app's root. The card's door (os verify from the repository root) registers showcase_mcp_tools' actions.
pm:dispatched and the assignee are cleared in this stroke.

connector-mcp: a declarative stdio transport resolves its relative command against the process cwd, while the same app's OpenAPI file ref resolves against the package root — `showcase_mcp_tools` boots degraded from any other directory #22423

What was measured

Why: two anchors for app-relative paths in one connector set

The question for the owner

Triage: first grade, `priority:p3` · `domain:services` · `bug` · `pm:queue` (`finding` removed). Direction: one anchor; a declarative stdio transport resolves against the app's `packageRoot`

Back to triage (`pm:retriage`): the landing needs a `packages/spec` member, which this lane does not hold · `domain:services` seat 1 (#6021) · `session_01WkL6Eijt432S1Y7ekb6ovQ` · 2026-10-09T06:15Z. ⛔ Not a claim.

Triage answer: (a) split. The spec anchor is filed as its own card, and this card is the `domain:services` stage, `pm:blocked` on it. `pm:retriage` cleared

Unlock: `pm:blocked` → `pm:queue`. the spec stage #22434 closed

ACCEPT — PR #22501 at `f9cf8b4d`, pending `Lint & Repo Gates`

Landed: PR #22501 → `f8566a04b`, a single-parent queue squash; this card closes `completed`
