Anonymous access	Handshake succeeds; 43 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.

43 tools usable without signing in

Get alerted when this contract changes

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.
