A plain GET returns the plaintext body "This URL can only be accessed with a MCP client." A JSON-RPC POST of either `initialize` or `tools/list` returns HTTP 401 with {"jsonrpc":"2.0","error":{"code":-32001,"message":"Authorization required"},"id":null}, so the live tool list and its inputSchemas could not be enumerated anonymously. The endpoint is provisioned by ReadMe, Clerk.io's documentation platform, and is scoped to the documentation corpus - it is not a Model Context Protocol wrapper over the api.clerk.io REST surface. No /.well-known/ oauth-protected-resource or /.well-known/oauth-authorization-server document is served on docs.clerk.io, so the authorization scheme is undiscoverable without credentials. tools: [] tools_note: NOT ENUMERATED. tools/list is auth-gated (HTTP 401). No tool list is published in llms.txt either, so there is nothing to record. No candidate tools are derived here - deriving them would misrepresent an auth-gated documentation MCP as an API-operations MCP. x-evidence: - url: https://docs.clerk.io/mcp method: GET http_status: 200 body: This URL can only be accessed with a MCP client. - url: https://docs.clerk.io/mcp method: POST jsonrpc_method: initialize http_status: 401 body: '{"jsonrpc":"2.0","error":{"code":-32001,"message":"Authorization required"},"id":null}' - url: https://docs.clerk.io/mcp method: POST jsonrpc_method: tools/list http_status: 401 - url: https://api.clerk.io/mcp method: GET http_status: 404 - url: https://docs.clerk.io/.well-known/oauth-protected-resource http_status: 404 checked: '2026-08-13'
