Recommended action: Host protected-resource metadata on the MCP server origin and make the AS metadata issuer exactly equal to the issuer identifier the client derives (including path/trailing slash).
Option: Align origins and issuer strings [evidence: documented_workaround]
Applies when: Server operators
Steps:
1. Serve resource metadata on the MCP server origin
2. Ensure AS metadata "issuer" exactly matches the authorization server URL used for discovery
Expected: Discovery succeeds
