Overview ¶
Package auth contains supporting helpers that enable fine-grained client side authorization when talking to an MCP server.
The Authorizer type can be attached to a client via `client.WithAuthInterceptor`. When a request is rejected with a *401 Unauthorized* response it automatically discovers the protected-resource metadata, obtains the necessary OAuth 2.1 token using the RoundTripper from the `transport` sub-package, and transparently retries the call.
