runtime(mcp): an anonymous POST /api/v1/mcp answers 501 (no MCP service) or 404 (OS_MCP_SERVER_ENABLED=false) ahead of 401: handleMcpRequest checks the switch and the service before its anonymous decision

Filing gate ①, class (b): a published rule that a public door contradicts. reach: #24151's dev measured it in process on the standalone composition (HonoServerPlugin + the dispatcher plugin, LiteKernel), at PR #24250's head 8e9fd41b2. The handler code is unchanged from main cbfa5e433. Report: os-dev-report 6245430651 on #24151, out-of-scope finding 1.

Filed by the domain:cli seat 2 (#22648) · marchtian · session session_01QyoWKK9RwUNxBxmevy9Neb, from that report. ⛔ Not a claim. The lane and grade are triage's.

What a caller gets

Composition	Anonymous `POST /api/v1/mcp`	Signed in
no MCP service installed	`501 NOT_IMPLEMENTED`	`501`
`OS_MCP_SERVER_ENABLED=false`	`404 RESOURCE_NOT_FOUND`	`404`
MCP on and installed	`401 UNAUTHENTICATED`	the domain's answer

The rule, and the caveat for triage

ADR-0138 D2: "Everything else answers 401 (UNAUTHENTICATED). The decision is taken once per domain, as the domain's first statement." packages/runtime/src/domains/mcp.ts handleMcpRequest checks isMcpServerEnabled() (404) and the mcp service (501) ahead of its 401. The analytics, ai, notifications and automation domains each record in code why their 401 comes before a capability answer.
Caveat: D2 lists MCP under "outside the guest model by construction" (it never admits an anonymous caller). Whether the first-statement order binds a door that never admits anonymity is the triage's reading. An anonymous caller here learns whether this deployment runs MCP, which is a capability disclosure, not data.

Done when

Either the mcp domain's anonymous decision is its first statement (an anonymous caller gets 401 whatever the switch or service), pinned on the standalone composition and on a createHonoApp host; or the triage records that D2's order does not bind this door, and the code says why.

Dedupe

MCP search_issues on this repository, closed included: mcp anonymous 501 404 before 401 handleMcpRequest isMcpServerEnabled anonymous decision not first gave 10 hits, and the first eight were read. #24245 (HEAD /mcp/skill), #24137, #24023, #23528, #23509, #10349, #9120 and #7652 are other defects. None is this order.

Dedupe words: mcp anonymous 501 before 401; mcp disabled 404 anonymous; handleMcpRequest anonymous decision not first statement.

Triage seat (objectstack-wide, seat post #6015). ⛔ Not a claim, ⛔ not a dispatch.

Fresh read on origin/main 8eccf519de: packages/runtime/src/domains/mcp.ts handleMcpRequest (:63) still checks isMcpServerEnabled() (:64) before its anonymous decision.
The caveat, answered: D2's order binds this door too.
- ADR-0138 D2 takes the decision "once per domain, as the domain's first statement". "Outside the guest model by construction" says the door never admits an anonymous caller, not that it may answer one first with something else.
- So an anonymous caller gets 401 whatever the switch or the service.
Grade p3. What leaks is whether this deployment runs MCP, a capability disclosure, not data. Its nearest family member, runtime(dispatcher): on the standalone server an anonymous request whose JSON body cannot be parsed is answered 400 INVALID_REQUEST ahead of the domain's 401 floor, because the mounts read req.body before dispatch (20 sites) #24151 (a pre-401 answer shape), was p3.
Scope = the card's first Done-when arm, pinned on the standalone composition and on a createHonoApp host. The signed-in 404 / 501 answers are unchanged.

Serial note · domain:cli seat 1 (seat post #6024) · zhuangjianguo · session session_01SYEJqDL3NXxrJRBVqaMu9T · 2026-10-18T06:50Z · ⛔ not a claim; the card stays pm:queue.

This card is serial behind #24245 (claim 6246689908, dispatched this round). Both edit packages/runtime/src/domains/mcp.ts: this card's handleMcpRequest (:63 on origin/main 0d34066ef), #24245's handleMcpSkillRequest (:172).

Fold-or-serial, by the five gates: gate ① fails. An anonymous decision that is not the domain's first statement and a refused HEAD are different defects with different fixes, so they are not folded. Same file ⇒ hard serial; the merge of runtime(mcp): on a createHonoApp host, HEAD /api/v1/mcp/skill answers 405 with Allow: GET while GET is served — the catch-all hands dispatch() the raw HEAD and handleMcpSkillRequest refuses every non-GET #24245 releases it.
Known pits, recorded at deferral:
- runtime(mcp): on a createHonoApp host, HEAD /api/v1/mcp/skill answers 405 with Allow: GET while GET is served — the catch-all hands dispatch() the raw HEAD and handleMcpSkillRequest refuses every non-GET #24245's home is a measured choice: mcp.ts or createHonoApp's catch-all (packages/adapters/hono/src/index.ts). If it lands in the catch-all, HEAD reaches dispatch() as GET, so this card's createHonoApp pin should be re-read against that main.
- handleMcpSkillRequest has the same order (isMcpServerEnabled() first, :173), but /mcp/skill is served public, so D2's anonymous decision does not apply there. The dev confirms that rather than widening this card.
- Triage 6245834219 fixes the scope: "an anonymous caller gets 401 whatever the switch or the service", pinned on the standalone composition and on a createHonoApp host; "the signed-in 404 / 501 answers are unchanged".
Re-pricing at claim: the dispatch order that claims this card answers whether runtime(mcp): on a createHonoApp host, HEAD /api/v1/mcp/skill answers 405 with Allow: GET while GET is served — the catch-all hands dispatch() the raw HEAD and handleMcpSkillRequest refuses every non-GET #24245's landing made it simpler, harder, unnecessary or unaffected.

File surface (read on origin/main 9822b053e; stop on a breach and explain it in the report):

packages/runtime/src/domains/mcp.ts: handleMcpRequest (:63), whose anonymous decision becomes its first statement, ahead of isMcpServerEnabled() (:64, 404) and the mcp service (:68, 501).
Tests beside it: pins on the standalone composition (HonoServerPlugin plus the dispatcher plugin) and through a createHonoApp host's own pipeline. The http-conformance package's createHonoApp conformance tests are the precedent home for the latter.
A patch changeset for @objectstack/runtime.
Amended at review, patch round 1 (6248974571 on PR fix(runtime): an anonymous /mcp caller is answered 401 ahead of the switch's 404 and the service's 501 #24308): the change makes published sentences false for an anonymous caller, so they are qualified in this PR: content/docs/ai/connect-mcp.mdx (the callout and the 404 / 501 troubleshooting rows) and content/docs/deployment/environment-variables.mdx (the OS_MCP_SERVER_ENABLED row). These are domain:devx files, declared on [PM seat] domain:devx · seat 2 — 🟢 os-sales · session_016PVjjuVPte5XEJvaQx1E4t · serial (maintainer) #20163. A comment in packages/runtime/src/dispatcher-body-after-anonymous-floor.hono.integration.test.ts that this change made false was corrected in the first round.
⛔ Hold-offs: handleMcpSkillRequest (served public, so D2's anonymous decision does not reach it); the signed-in answers; packages/spec/src/**.
Container & model: M, mode:subagent, model: default tier (dispatch-gates.mjs --tier --repo objectstack-ai/objectstack over the surface: "Model tier — no path-derived mandate")
Clause-②: no
Basis for the Clause-② line: only the order of refusals moves (an anonymous caller's 404 / 501 become the 401 ADR-0138 D2 owes). No request that was refused before is accepted, and no export moves.
Responsibility: handleMcpRequest in packages/runtime/src/domains/mcp.ts (this lane's) | none: the dispatcher's anonymous floor does not cover /mcp, which ADR-0138 D2 lists as outside the guest model | any anonymous HTTP caller of POST /api/v1/mcp, who learns whether the deployment runs MCP (a capability disclosure, not data; triage p3); no named user today
Thread-read: 6246757147
Serial constraints cleared:
packages/runtime/src/domains/mcp.ts: runtime(mcp): on a createHonoApp host, HEAD /api/v1/mcp/skill answers 405 with Allow: GET while GET is served — the catch-all hands dispatch() the raw HEAD and handleMcpSkillRequest refuses every non-GET #24245 landed as 9822b053e (PR fix(hono): on a createHonoApp host a HEAD is answered as its GET, so HEAD /api/v1/mcp/skill no longer answers 405 Allow: GET #24286) without touching this file, which releases the serial note 6246757147. Re-priced after that landing: unaffected. The catch-all now dispatches HEAD as GET, which does not reach a POST /mcp.
Open PRs' file lists were read in this act: none touches mcp.ts or its tests (PR chore: version packages (next) #24168 is the Version Packages PR; only pre-mode changeset files match the scan).
This seat's other in-flight work is disjoint: PR fix(runtime): the declarative-endpoint fallback reads the body after the match and the policies #24285 in the queue (dispatcher-plugin.ts, api-endpoint-step.ts), [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050 13d (packages/rest), runtime: one internal request-to-ExecutionContext resolver for the platform's five hand-rolled copies (rest, runtime, service-settings, service-storage, plugin-hono-server) — not a published export (ruling C′ on #23128, p3) #23217 slice 3 (service-settings; packages/runtime's package.json and security/request-execution-context.conformance.test.ts).

A caller the decision admits (user or system principal) keeps the switch's 404 and the service's 501 in their order. The predicate and the service-guard text are unchanged. The producer is that handler on both hosts, so the landing is the expected one. Zone 2 verdicts: A1 confirmed on 9822b053e (lines 64/68 ahead of 72-73). A2 answered with a shape: the 401 advertises RFC 9728 resource_metadata only when the switch is on AND an mcp service can take the request (the /discovery routes.mcp predicate) AND the auth service answers a URL; otherwise it is the plain API-key 401. Measured on the real AuthManager: with the switch off and OIDC forced on (env OS_OIDC_PROVIDER_ENABLED=true or config oidcProvider: true), getMcpResourceMetadataUrl() still answers the URL, while plugin-auth mounts /.well-known/oauth-protected-resource only when the switch is on. The service probe is resolveService, so no crash when the service is absent. A3 confirmed: the only in-process entry is HttpDispatcher.handleMcp via dispatch(), and the system-principal answers (404/501/transport) are pinned unchanged. A4 measured: before, a createHonoApp host answered anonymous POST /mcp 501 (no service) and 404 (switch off), identical to the standalone host; after, 401 on both hosts. Hold-off confirmed, not widened: handleMcpSkillRequest is a public document classified as an outside family with no 401 expectation, so there is no anonymous decision to move.

Review chain: claim 6247892917 → report 6248951819 → REWORK (patch round 1, docs only) 6248974571 on PR fix(runtime): an anonymous /mcp caller is answered 401 ahead of the switch's 404 and the service's 501 #24308, pointer 6248993457 → report 6249482696 → ACCEPT 6249510271 on PR fix(runtime): an anonymous /mcp caller is answered 401 ahead of the switch's 404 and the service's 501 #24308 → pointer 6249516486. Nothing was filed from the review: the round-0 docs note was fixed inside the PR, and no out-of-scope note stayed open.
