How to authenticate

Checked against the endpoint by our probe on 17 Oct 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; 6 tools listable

What the probe found

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.
