  SignalWire's only live MCP surface is a Fern documentation-search server. It shares NO backing
  operation with either OpenAPI contract, so the crosswalk is deliberately lopsided: one mcp_only
  row and 332 rest_only operations. Recording the divergence is the point — an agent that connects
  to https://signalwire.com/docs/_mcp/server can read the docs but cannot place a call, send a
  message, or provision a number. Nothing here is mapped by guesswork.

mcp_only:
- tool: searchDocs
  reason: >-
    Full-text search over the published documentation corpus. There is no REST operation, OpenRPC
    method, or GraphQL field behind it — it is a docs-platform capability, not a product API.

  signalwire_rest: 253
  compatibility: 79
  calling_openrpc: 8
  total: 340
  reason: >-
    No MCP tool binds to any product operation. Every REST operation and every JSON-RPC method is
    REST-only with respect to the MCP surface.
