How to authenticate

Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	No auth
Protected-resource metadata	✕Not found Without it a client has to guess where the authorization server lives.
Anonymous access	Handshake succeeds; 31 tools listable
Credentials demanded in prose	✕mu_register, mu_verify, mu_status, mu_quote, mu_check, mu_spec_draft, mu_rfq_record, mu_create_store These tools are listed anonymously and their own descriptions ask for an account or key, but no challenge is issued — so a client has nothing to act on and the refusal arrives as a tool error.

What the probe found

warningTools needing credentials are listed without a challenge

8 of the 31 tools listed anonymously say in their own descriptions that they need an account or a key (mu_register, mu_verify, mu_status, mu_quote, mu_check, mu_spec_draft, mu_rfq_record, mu_create_store), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.

No CORS headers for browser-based clients

A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.
