Protected resource metadata

/.well-known/oauth-protected-resource/api/mcp

A plain browser GET returns 405 by design. Configure the URL as an HTTP MCP server. The client initializes the protocol over POST and follows the OAuth metadata when a protected tool needs access.

HTTP API

The public HTTP API and its OpenAPI document come from the same Effect HttpApi contract. The OpenAPI document covers HTTP routes, not MCP tools.
