ci(traceability): enable corepack for the SDK build#289
Merged
Conversation
The refresh run failed with 'pnpm: not found' — the reference SDK's build command (typescript-sdk: pnpm install && pnpm run build:all) needs pnpm on PATH. Add 'corepack enable' to the run job.

* Add SEP-2350 scope-accumulation check to auth/scope-step-up SEP-2350 clarifies that on step-up re-authorization, clients SHOULD compute the union of previously-granted and newly-challenged scopes so they don't lose permissions for other operations. - Traceability yaml: 1 client check (two spec sentences merged), 1 server check tracked for a future server-side scenario, 1 excluded reword - ScopeStepUpAuthScenario now challenges with only the missing scope so union accumulation is observable on the second authorization request - New check sep-2350-scope-union-on-reauth (WARNING when the previously granted scope is dropped) - everything-client withOAuthRetry now accumulates prior token scope into the re-auth scope (passing example) - New auth-test-echo-scope negative client + vitest case * feat: add client conformance tests for SEP-2575 (#270) * feat: merge latest request-metadata scenario stacked branch * test: implement optional capability conditional checks and simulated negotiation retry * fix(sep-2243): collapse check IDs to one-per-requirement (#287) The sep-2243 scenario check IDs drifted from the requirement-traceability yaml in #259 — the code emitted one ID per test case while the yaml declares one per normative requirement, so the IDs no longer matched. Rename the emitted IDs so a check ID maps to a single MUST/SHOULD and is emitted once per case (the per-case detail moves to name/description), matching the repo's existing 'same id, vary status/message' convention: - mcp-method-header-* / mcp-name-header-* -> client-includes-standard-headers - reject-invalid-tool-* / keep-valid-tool -> client-reject-invalid-tool - server-accepts-{lower,upper}case-name -> header-name-case-insensitive - server reject status checks (mismatch/missing/case x method/name) -> server-reject-invalid-headers - their error-code variants -> server-reject-error-code Merge the yaml's server-reject-mismatch + server-reject-status into one server-reject-invalid-headers MUST (HTTP 400 on a header-validation failure); keep server-reject-error-code as the SHOULD. Base64/custom-header rejection checks keep their own param-validation IDs (out of scope here). Gates and the whitespace-acceptance check keep their scenario-matching names. No behavior change — only check IDs, descriptions, and the yaml. * feat: `sdk` subcommand to run local conformance against any SDK ref (#277) * feat: add sdk subcommand to run conformance against any SDK ref (#250) * Revise sdk runner: explicit --mode, KNOWN_SDKS-only config, v1/v2 entries Addresses review feedback on the sdk subcommand: - Require --mode (client|server) and remove "both". Each invocation now tests exactly one side with its own exit code; the old default ran client then server but combined exit codes with ||=, which skipped the server side entirely whenever the client run failed. - Resolve build/run config from KNOWN_SDKS + CLI flags only; drop the conformance.config.yaml loader (no SDK ships one yet). The Zod schema stays as the type for the built-in entries. - Split the typescript entry by major version: typescript-sdk (v2/main, pnpm install + build:all, expected-failures.yaml) and typescript-sdk-v1 (v1.x, npm ci + build, conformance-baseline.yml). An entry may set `repo` (real clone target for an alias) and `defaultRef` (branch used when no @ref is given). parseSdkSpec now leaves ref undefined when omitted so defaultRef can apply; a trailing @ is treated as no ref. - Key the clone cache by ref (<repo>/<ref>) so different refs of the same repo no longer share one checkout. - Bound the server readiness probe with a per-request AbortSignal timeout so a server that accepts the socket but never responds can't hang past the overall deadline. * fix(sdk-runner): resolve -o to absolute path; add --expected-failures override; replaceAll for safeName * feat: add SEP conformance traceability manifest (#288) squashed; see PR #288 body * feat: add server conformance tests for SEP-2575 (#271) * feat: add server conformance tests for SEP-2575 * refactor and add new checks * Fix stateless scenario source field and report SKIPPED for inapplicable capability checks - Add the required `source` field (DRAFT) so the scenario typechecks and is selectable via --spec-version. Without it the class did not satisfy the ClientScenario interface and s.source was dereferenced by the spec-version filter at list time. - Teach runCheck about a SKIPPED status and use it for the two client-capability checks when the server does not return -32003, instead of reporting a green PASS for a requirement that was never exercised. * Remove unimplemented placeholder checks from stateless server scenario The subscriptions/listen, statelessness-invariant, list-changed and disconnect-is-cancel checks emitted SUCCESS without probing the server, which inflated coverage in the traceability report. Drop them until they have real assertions; the corresponding rows remain declared in src/seps/sep-2575.yaml so traceability shows them as not-yet-covered. Also fix the checkErrorId helper to push under the sep-2575-http-server-error-jsonrpc-id slug so its failure path actually short-circuits the aggregate SUCCESS check at the end of the scenario. --------- Co-authored-by: Paul Carleton <paulc@anthropic.com> * SEP-2352: authorization-server migration scenario (#286) * Add SEP-2352 authorization-server migration scenario SEP-2352 requires that client credentials are bound to the issuing authorization server: when PRM authorization_servers changes to a new issuer, clients MUST re-register and MUST NOT reuse the previous AS's client credentials. - Traceability yaml: 3 checks, 3 excluded (internal state / UI) - New auth/authorization-server-migration scenario (draft suite): two auth servers; PRM flips from AS1 to AS2 after the first authenticated request; AS2 asserts it received a fresh /register and never saw AS1's client_id at /authorize or /token - ConformanceOAuthProvider gains invalidateCredentials and bindIssuer so the everything-client can key credentials by issuer (passing example) - everything-client adds an issuer-aware handler for this scenario that re-reads PRM on each 401 and rebinds before re-authorizing - auth-test-reuse-credentials negative client + vitest case * Drop application_type from DCR metadata (not in SDK OAuthClientMetadata type) --------- Co-authored-by: Paul Carleton <paulc@anthropic.com> * ci(traceability): enable corepack so the SDK build can use pnpm (#289) The refresh run failed with 'pnpm: not found' — the reference SDK's build command (typescript-sdk: pnpm install && pnpm run build:all) needs pnpm on PATH. Add 'corepack enable' to the run job. * ci(traceability): tolerate SDK conformance failures in the run step (#290) The `sdk` command exits non-zero when the SDK has conformance failures not in its baseline. The traceability manifest only needs the emitted check IDs (written regardless of pass/fail), so a failing SDK must not fail the refresh. Add `|| true`; the existing 'no results produced' guard catches a genuinely broken run. * chore: refresh SEP traceability manifest (typescript-sdk@main) (#291) Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> * Make scopesSupported disjoint from challenge scopes so the SEP-2350 union check can't be satisfied by scopes_supported ∪ challenge A client that unions scopes_supported with the challenge — instead of its prior grant with the challenge — would have requested mcp:basic mcp:write and falsely passed sep-2350-scope-union-on-reauth, since scopesSupported happened to coincide with the previously-granted scope. Setting it to a disjoint value makes the check actually require the prior token's scope. Spec backing: clients MUST NOT assume any set relationship between the challenged scope set and scopes_supported, so a disjoint advertisement is realistic. * SEP-837: application_type check in DCR registration (#284) * Add SEP-837 application_type check to DCR registration SEP-837 requires MCP clients to specify an appropriate application_type during Dynamic Client Registration so OIDC authorization servers can apply the correct redirect-URI constraints. - Traceability yaml: 1 check (presence + valid value), 4 excluded (class-specific SHOULDs unobservable; UI/robustness) - Check added in the shared createAuthServer DCR handler so it fires in every auth scenario that performs DCR (no new scenario) - withOAuthRetry now sets application_type: native (passing example; the conformance example clients are CLI tools) - New auth-test-no-application-type negative client + vitest case * Widen ConformanceOAuthProvider metadata type for application_type Fixes CI typecheck (TS2353 at withOAuthRetry.ts:76): the SDK's OAuthClientMetadataSchema doesn't include application_type yet. registerClient() spreads clientMetadata verbatim into the /register POST body, so a local type intersection is sufficient to get the field on the wire without an SDK release. * Set application_type in runAuthMigrationClient The SEP-2352 authorization-server-migration handler constructs its own ConformanceOAuthProvider (not via withOAuthRetry), so it was missing application_type after rebasing onto main. The scenario does DCR twice (old AS, new AS) and the SEP-837 check fires on each. --------- Co-authored-by: Paul Carleton <paulc@anthropic.com> * feat: add conformance tests for iss parameter (SEP-2468) (#220) * feat: add conformance tests for iss parameter (SEP-2468) Adds 5 draft conformance scenarios testing RFC 9207 issuer parameter validation in OAuth authorization responses: - auth/iss-supported: server advertises support and sends correct iss - auth/iss-not-advertised: server omits iss parameter entirely - auth/iss-supported-missing: client must reject missing iss when required - auth/iss-wrong-issuer: client must reject mismatched iss value - auth/iss-unexpected: client must reject iss when not advertised Also adds auth-test-iss-validation.ts, a reference client that correctly validates iss per RFC 9207, and negative tests confirming the standard client fails all three rejection scenarios. TODO: Update RFC_9207_ISS_PARAMETER spec reference once SEP-2468 (modelcontextprotocol/modelcontextprotocol#2468) is merged. * update scenarios * fix: createAuthServer iss option type/guard and NotAdvertised scenario duplication The doc comments said 'Default: not included' but the destructure defaulted to true/'correct', and the `!== undefined` guard at L155 was unreachable — so there was no way to omit the metadata field, and IssParameterNotAdvertised silently advertised support (a duplicate of IssParameterSupported). Kept the on-by-default behavior (mock AS models a well-behaved server) but made issParameterSupported `boolean | null` so callers pass null to omit, matching the codeChallengeMethodsSupported pattern. Doc comments now match. Scenarios that need omission pass null/'omit' explicitly. * fix: rejection scenarios silently pass when client never reaches auth endpoint correctlyRejected = !tokenRequestMade reports SUCCESS if the client errors out before hitting /authorize. Gate on authReached so a setup failure shows as FAILURE with authReached:false in details. * fix: iss-unexpected scenario contradicts SEP-2468 spec table row 3 The spec table says: supported=false/absent + iss present -> *Compare* to the recorded issuer (not reject). The scenario sent a *correct* iss and FAILed compliant clients for proceeding after a successful comparison. Now sends a mismatched iss so the comparison fails and rejection is the spec-required outcome. Reference client updated to compare-when-present instead of throw-on-presence. * refactor: replace harness-config checks with client-proceeded checks iss-advertised-in-metadata / iss-sent-in-redirect (and the not-* variants) fired in onAuthorizationRequest before the redirect happened, asserting only that the harness was configured correctly — a client that ignores iss passes identically. Replaced with one check per scenario keyed on tokenRequestMade, which observes that the client actually proceeded through the iss path. * refactor: rename check IDs to sep-2468-* and align with spec table rows One ID per spec table row; auth/iss-supported and auth/iss-wrong-issuer both emit sep-2468-client-compare-iss-supported (same comparison, opposite input) per the same-slug-for-SUCCESS-and-FAIL convention. * feat: add sep-2468.yaml requirement traceability 8 check rows (4 client table-row checks, 1 metadata-issuer, 2 AS-side, 1 no-normalization), 1 excluded (error-display is UI-facing). The record-issuer MUST is merged into the compare-iss-supported row text since it has no independent wire observation. * fix: migrate iss scenarios specVersions->source (post-#265) Replaces `specVersions: ['draft']` with `source: { introducedIn: DRAFT_PROTOCOL_VERSION }` in the 5 iss-parameter scenarios. This commit typechecks once the stack is rebased onto main >= #265 (the ScenarioSource migration). Adding it now so the rebase is mechanical. * fix: include application_type in iss-validation example DCR (post-#284) The SEP-837 application_type check now runs in every auth scenario; the hand-rolled DCR in auth-test-iss-validation.ts was omitting the field. --------- Co-authored-by: Paul Carleton <paulc@anthropic.com> --------- Co-authored-by: Anubhav Dhawan <anubhavdhawan@google.com> Co-authored-by: Paul Carleton <paulcarletonjr@gmail.com> Co-authored-by: Yuan Teoh <45984206+Yuan325@users.noreply.github.com> Co-authored-by: Paul Carleton <paulc@anthropic.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> Co-authored-by: Max Gerber <89937743+max-stytch@users.noreply.github.com>
