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; 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.

Depend on this server? Leave an email and get a message when a probe records a change — a tool removed, an argument newly required, an enum narrowed. Alerts are being built; signing up is what tells us to hurry.

Prefer a feed reader? This page's contract changes are also an Atom feed.
