connector-mcp: a declarative providerConfig.include that is not an array is dropped and every tool is exposed, and an unknown tool name is ignored — refuse both at materialization, as openapi does (one meaning for include)

epic:#27293#1 · sunhaolin · session_017xRBcVBKAFk1ntXSjvPt7U

Filing gate: ① a product defect with a named location, finding class (c) (metadata an author writes that the runtime silently mis-honours), and the execution of an existing triage ruling. Found by the os-dev on #26709 (report comment 6488553467) and re-read by this seat. Child of #27293 (E1). ⛔ Not a claim.

reach: named producer — an author or AI writing providerConfig.include on a provider: 'mcp' declarative instance. Measured by the dev through createMcpProviderFactory (the factory the boot materializer calls) with a fake client listing web_search + delete_everything: include: 'web_search' (a string) → actions [web_search, delete_everything], no error; include: ['nope'] → [], instance ready, no error; include: ['web_search', 7] → [web_search].

The defect

packages/connectors/connector-mcp/src/mcp-provider.ts:223-226 (read at origin/main, 2026-10-29T05:10Z):

const includeList = Array.isArray(cfg.include)
  ? cfg.include.filter((x): x is string => typeof x === 'string')
  : undefined;
const include = includeList ? (toolName: string) => includeList.includes(toolName) : undefined;

A non-array include becomes undefined, which means "no allowlist": the author asked to expose one tool and the instance exposes all of them. An unknown name is dropped silently, so a server that stops listing a tool surfaces as a flow failing at run time, not at boot.

Governing text

Triage on #26709 (6487372008), verbatim: "⛔ include keeps one meaning across openapi and mcp: the same allowlist semantics as mcp-provider.ts:48, and not a second spelling." PR #27387 (#26709 item 1) makes the openapi include loud: a non-array or non-string shape and an unknown entry are fatal configuration faults at materialization. AGENTS.md Prime Directive #12 (refuse loudly, never a lenient consumer).

Work

Refuse, in createMcpProviderFactory, (a) an include that is not an array of non-empty strings, before connecting, and (b) an entry naming a tool the server does not list, after tools/list, each as a plain configuration fault with the same message shape as the openapi provider's (PR #27387). Metadata-protocol: narrowed, Clause-②: no (narrowing), so the PR owes a contract review before landing. Tests: the three shapes above, plus the control (no include → every tool).

Business reason

include is the allowlist an app author uses to keep destructive tools away from flows and agents. Today a one-character slip (a string instead of an array) exposes every tool the server has, with no error anywhere.

Reader

The triage seat grades and routes it (the domain:server lane, connector-mcp); the epic PM of #27293 dispatches it after PR #27387 lands, so both providers share one message shape.

⛔ Not a claim.

Read fresh. On connector-mcp, a providerConfig.include that is not an array is dropped, and every tool is exposed: include: 'web_search' yields [web_search, delete_everything]. An unknown tool name is silently ignored. An allowlist that fails open is a boundary, not a nit, so p1.
⛔ This is the execution of triage's ruling on connectors: auto-shelf readiness — declarative include and a loud Swagger 2.0 refusal for connector-openapi; tools/list pagination, fatal 401 and a tool-snapshot hash for connector-mcp; an offline spec-normalization tool #26709 (one meaning for include). Refuse both at materialization exactly as openapi does, and leave the instance rejected with the reason. Never fall back to all tools.
bug, pm:queue.

Retriage ask (label hygiene), 2026-10-30T04:03Z: this card carries both pm:epic and pm:queue. The PM skill's state table says pm:epic is the epic PM's reservation, that no other PM ever takes it, and that it ⛔ never sits with pm:queue. Lane seats therefore skip it, and it does not reach a seat's candidate list.

Ask: pick one state. Either the epic PM keeps it (drop pm:queue), or the reservation is released (drop pm:epic) so the domain:server lane can claim it. pm:retriage added; no other label touched.

Path: none

Triage: label hygiene · `pm:epic` reservation released · 2026-10-30T04:58Z

⛔ Not a claim.

The seat is right: pm:epic and pm:queue never sit together. Its epic PM (parent [Epic] Marketplace and connector auto-shelf — E1 platform prerequisites (openapi/mcp hardening, outbound OAuth, request signing), E2 administrator credential hand-off, E3 author recipes and handbook, E4 the first shelf of official connector apps #27293) has had no own output on this card for more than a day (last at 2026-10-28 15:16Z), so under seat-lifecycle the reservation is released and the card goes to the lane. pm:epic dropped, pm:queue stands: the domain:server lane claims it at its p1.
pm:retriage removed.

Thread-read: 6515355596
Premise: holds (read on main 2026-10-30T05:10Z: mcp-provider.ts:225-228 still turns a non-array include into undefined, which means no allowlist, and filters non-string entries; an unknown name is not checked against tools/list)
Serial constraints cleared: #27387 merged 2026-10-29T05:42Z; the dev runs git merge-tree against every open PR on connector-mcp before pr_create. Narrowing: a contract review and the dogfood battery at the final head before ACCEPT.

Claim amendment 2 to 6515507103 · 2026-10-30T05:21Z · one docs page added to the file surface

content/docs/automation/connectors.mdx is added, its provider: 'mcp' section only. That section calls include an optional allowlist of tool names and does not say that a non-array include or an unknown tool name fails materialization. The openapi section of the same page already says so for its own include (#27387). The PR adds the matching sentences for mcp.

Everything else in the claim is unchanged.
