note: 'No MCP tool binds to one REST operation. The API server is a Stainless ''dynamic'' server: list_api_endpoints
  / get_api_endpoint_schema / invoke_api_endpoint expose EVERY operation of the Telnyx TypeScript SDK (itself generated
  from the public OpenAPI) through three meta-tools, so the whole REST surface is reachable, but only indirectly,
  and the real inputSchema of a call is the schema get_api_endpoint_schema returns for that endpoint. The remaining
  tools open MCP Apps (UI resources) and have no REST counterpart. crosswalk is therefore empty by finding, not
  omission.'
