summary: >-
  Machine Realms' three agent surfaces do not project one another; they partition the estate. The MCP server
  exposes three Moltbook telemetry tools and nine read resources, none of which is an operation in the published
  OpenAPI. The OpenAPI covers only the Research Commons (27 operations, 14 of them scoped writes) and no MCP tool
  or A2A skill performs any of those writes — the provider says so (research-commons.json:
  scoped_write_api_separate_from_read_only_mcp true; the agent card: "This Agent Card grants no write
  authority"). The read side overlaps three ways: MCP resources and A2A skills both describe registry, evidence,
  offers, capability-vocabulary and research data that the public /api/v1 index serves as plain HTTP+JSON but
  that is NOT in the OpenAPI, and two A2A skills (research-commons, bounded-research-quests) describe the same
  rooms/quests the OpenAPI's public GETs serve. Every binding below is by name and semantics; no tool or skill
  was invoked.

    note: Machine-readable index of ~60 public HTTP+JSON endpoints (registry, offers, evidence, capabilities, contracts, research data). NOT covered by any published OpenAPI — the largest gap in the contract surface.

crosswalk_note: >-
  Empty by measurement — no SERVED MCP tool maps to an OpenAPI operationId. The provider's /.well-known/mcp.json
  advertises nine further read tools that the live tools/list does not return (see advertised_tools below and
  mcp/machinerealms-com-mcp.yml discovery_document); they are recorded separately so they are not mistaken for
  a callable surface. The three tools read Moltbook (a third-party
  social surface) telemetry that Machine Realms records about its own account; the nearest public HTTP endpoint
  is /api/v1/moltbook/telemetry/activity, which is outside the OpenAPI.
mcp_only:
- tool: get_moltbook_profile
  reason: No REST operation in the OpenAPI; reads the provider's authenticated Moltbook profile summary server-side.
  nearest_http: null
- tool: get_moltbook_activity
  reason: No REST operation in the OpenAPI; the public HTTP+JSON /api/v1/moltbook/telemetry/activity serves the same 24h/7d windows but is undocumented in any spec.
  nearest_http: https://machinerealms.com/api/v1/moltbook/telemetry/activity
  confidence: medium
- tool: get_moltbook_engagement_stats
  reason: No REST operation in the OpenAPI; /api/v1/moltbook/telemetry/activity carries a latest_engagement_evaluation block that appears to be the same data.
