MCP Router: protocols.stateless.toolsListCacheScope

toolsListCacheScope declares the privacy scope of cached stateless tools/list responses.

  • Type: String
  • Default and only supported value: private

Tool visibility is authorization-sensitive, so cache entries are keyed by principal fingerprint, policy/config revisions, protocol version, and relevant headers. The gateway reports cacheScope: private; configuring another value rejects the stateless profile.
