Will my client connect?

Decided from what the probe found at the endpoint, and from what each client's own documentation says it can complete. Every row carries the day that documentation was read.

The handshake was refused with no challenge and no OAuth metadata, so what this server wants is not something the probe could record.

How to authenticate

Checked against the endpoint by our probe on 18 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	Unknown
Protected-resource metadata	✕Not found Without it a client has to guess where the authorization server lives.
Anonymous access	Refused — credentials required

What the probe found

warningThe server refused to initialize

It speaks JSON-RPC but rejected the handshake: {"code":"402","message":"Payment required"}

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.
