- personal tokens only behind mcp.allow_personal_tokens (401 without a
lookup otherwise); an admin token yields a backend-only identity with
its scope limit per dispatched method, a user token a frontend-only one
- read/write ceiling and prompts proven by the tracer's subtests; the
audit line asserted to carry the tool and never the arguments or token
- the mounted *pier.Pier is published on the application (test seams in
export_test.go)
- docs/services/mcp.md with the tested acme.blog example, site.yaml note,
cross-links from authentication.md, registration.md and the surf README
- store_redis.go: records with PX TTLs, per-binding sets, pub/sub events,
opened lazily from redis.url under cooler's prefix (nothing dials at mount)
- events.go: pact.MCPSubjectChanged republished through the store; every
instance recomputes the subject's sessions and stateless servers
(list_changed) or ends them on revocation; the link cache is dropped
- stateless.go: the SDK's stateless handler over per-identity servers for
2026-07-28 clients, routed by the protocol header or server/discover
- prm.go: RFC 9728 metadata at both well-known paths; long GET streams
re-verify their bearer every minute
- TestPierSessionsSmoke, TestPierFanOutSmoke, TestPierStatelessSmoke on
miniredis; README features, configuration and operational notes
- modules/pier: Host contract, mcp.* config, catalog compiled from
pact.HasMCP (prefixing, route binding, guard resolution, schema
reflection, annotations), per-request identity through the published
verifier and resolvers, built-in backend guard provider, in-process
dispatch with the bouncer marker, per-identity SDK server with the
per-request re-filter, stateful session router with rehydration over a
memory store, audit lines
- modules/surf/pier_on.go: the summercms_mcp hook adapting the router to
pier.Host; the untagged hello binary carries no SDK
- go.mod: go-sdk v1.8.0 and jsonschema-go v0.4.3 (decision note committed
before this change)
- TestPierTracerSmoke: SDK client lists and calls acme_echo end to end
through surf's compiled guard chain; README and root table row
