# Retrieve the authorization server metadata (path form)

GET https://api.modulards.com/.well-known/oauth-authorization-server/mcp

Returns the same authorization server metadata document as "Retrieve the authorization server metadata", at the path RFC 8414 defines for a client that appends the resource path (here `mcp`) to the well-known address. Use whichever form your client builds.

Public, served at the root of the MCP host, without the `/api` prefix.
