method: derived
source: Derived by comparing the documented Kimetsu MCP tool list (mcp/kimetsu-dev-mcp.yml, from https://kimetsu.dev/docs/how-kimetsu-works/interfaces/)
  with the provider-published Agent Gateway OpenAPI 3.1.0 (openapi/kimetsu-dev-agent-gateway-openapi.yml, 15 operations).
purpose: 'Record, honestly, that this provider''s MCP surface and its REST surface are two different products with
  zero overlap: the MCP tools operate a local SQLite memory brain on the developer''s machine; the REST operations
  are anonymous discovery reads over public Sidequest Commons feeds on agents.kimetsu.dev. No tool is backed by
  a gateway operation and no gateway operation has a tool, so every row lands in mcp_only or rest_only. The crosswalk
  exists so the divergence is data rather than an absence.'
surfaces:
  rest_openapi: openapi/kimetsu-dev-agent-gateway-openapi.yml
  rest_original: openapi/_original/kimetsu-dev-agent-gateway-openapi.json
  rest_base: https://agents.kimetsu.dev
  mcp: local stdio (`kimetsu mcp serve`); no hosted endpoint
  mcp_gated: false
  mcp_introspected: false
  mcp_note: Not gated by auth, but not reachable over the network; tools/list requires running the binary locally,
    which this pass did not do. Tool names come from the provider's own docs.
