These members concern MCP OAuth handling when a server does not challenge unauthenticated requests, such as Google's Gmail MCP, including forcing the OAuth flow after a 200 response to initialize. One member also mentions honouring a configured oauth.scope and accepting Google's root-slash issuer, which are adjacent OAuth details.
