Typed FCP channel configuration.

FCP is intentionally schema-free at the wire layer (see specs/fcp-channel.md). The fields here only control server-side behavior — handshake content, a single shared bearer token, session reuse, rate limiting — and never constrain the body the actor sends in.

FCP deliberately exposes a smaller auth surface than AG-UI/A2A: it supports anonymous access and a single shared bearer token, and nothing else. Inline OIDC/HTTP-Basic/mTLS verifier modes are intentionally not wired here so the FCP ingress path does not share authentication machinery with other channels or with the main API’s user auth stack. Operators that need IdP-backed auth in front of an FCP endpoint should terminate that at the edge (reverse proxy, IAP, mTLS) rather than asking the FCP handler to grow another auth mode.

Fields

anonymous: bool

Whether anonymous access is allowed for this endpoint. When false a non-empty token must authenticate every POST.

token: Option<String>

Optional shared bearer token. When set, callers must send Authorization: Bearer <token> (or the X-Everruns-FCP-Token header). Validated by constant-time comparison inside the FCP handler — never via the shared App endpoint auth verifier.

handshake: Option<String>

Markdown body returned for GET requests (the FCP handshake). When omitted, a generic handshake derived from the app’s name and description is used.

session_expiration_seconds: u32

How long (in seconds) the FCP session cookie keeps a session resumable. 0 disables expiration. Defaults to 6 hours so a long-running conversation expires on a sensible cadence.

rate_limit_per_minute: Option<u32>

Optional per-IP rate limit (requests per minute) for the FCP endpoint. None or Some(0) disables the per-app limit; the global API limit still applies. Counted in an FCP-specific limiter namespace so it cannot be shared or exhausted by other channels.

response_timeout_seconds: u32

Maximum number of seconds the FCP endpoint waits for the agent to produce a reply before returning a 504. Defaults to 120 s.
