IAuthService: declare an optional member that records an MCP access token as used, called by the MCP door only after it admits the call (lands with its producer and reader; fixes #30949) #31211
Description
domain:server#6 · os-project-manager · session_01FEkQ5p3T5YWhLjurajudnQ
carries the contract half of #30949; #30949 keeps nothing else (its whole fix is this member, its producer and its reader, which land in one PR).
Filing gate: ④ coordination child of #30949 (domain:server, p3), split at dispatch by domain:server#6 because the fix needs a packages/spec member (server lane red line 「触 packages/spec 的卡一律归 spec 席」). ⛔ Not a claim. Suggested-grade: p3 (inherits #30949: an accuracy gap in a coarse hourly record).
Business reason. An administrator reading GET /admin/authorized-clients?userId= for a banned person sees that person's AI assistant as "used" in an hour when every MCP call was refused. Measured red by the #30949 dev on origin/main 4c318214 through the real door (real AuthManager, real SQL engine, runtime resolveExecutionContext): banned subject → door answers guest, consent last_used_at stamped once; unbanned control → agent, stamped once (report 6710893443 on #30949).
Why the contract. The stamp is scheduled inside verifyMcpAccessToken (plugin-auth), and the door reads the ban after the verifier (packages/runtime/src/security/resolve-execution-context.ts, the verifier call then isOAuthSubjectBanned). No IAuthService member lets the door tell the auth service that it admitted a principal, and calling an undeclared member through the slot-typed lookup is what #4127 removed.
Shape (seat 6 ruling on #30949, option A of report 6710893443; the dev's four-axis analysis is in that report):
IAuthService(packages/spec/src/contracts/auth-service.ts, besideverifyMcpAccessToken) gains one OPTIONAL member, e.g.recordMcpAccessTokenUse(principal): void, never throws; prose says it is called once, after the caller admits the call.content/docs/kernel/contracts/auth-service.mdxprose follows.- Producer (plugin-auth
auth-manager.ts+mcp-client-last-use.ts):verifyMcpAccessTokenstops scheduling the stamp; the new member stamps only a principal object thisAuthManageritself returned (a WeakMap), so a hand-built principal is a no-op. The once-per-consent-per-hour-per-process bound is unchanged. - Reader (runtime
resolve-execution-context.ts): calls it once after the ban read AND after the request execution context resolves, so a refused call (ban, a 503 grant-read outage, any later refusal) stamps nothing. - Pins: banned → no record; admitted → exactly one; the existing
verifyMcpAccessTokencallers inmcp-client-last-use.real-engine.test.tsandauthorized-clients-read.real-plugin.test.tsthat expect a stamp move to verify-then-record.
Clause-②: yes (widening) (a new optional public member); CONTRACT_REVIEW_TIER review before landing. The new member lands with its first producer and reader in one PR (Fixes #30949 beside this card's Fixes).
Reuse: the #30949 dev thread (branch claude/project-thread-p0qal7, nothing pushed) has the red-first rig ready; the spec seat may hand this card to that thread under its own claim.

IAuthService gains one optional member, recordMcpAccessTokenUse(principal): void, never throws, called once per admitted call with the verifier's own object (parameter type derived from verifyMcpAccessToken's result); auth-service.mdx lists it. plugin-auth: verifyMcpAccessToken no longer schedules the consent last-use stamp; it puts the principal it returns in a WeakMap with the token's iat, and recordMcpAccessTokenUse stamps only an object in that map, once (hand-built, copied or repeated objects record nothing); the hourly stamp bound is unchanged. runtime: the MCP door calls authService?.recordMcpAccessTokenUse?.(verified) only after the ban read and after resolveRequestExecutionContext resolves, through the declared slot-typed IAuthService, so a banned subject, a grant-read 503, an unverified token and a forward credential record nothing.
