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.

How to authenticate
Checked against the endpoint by our probe on 4 Nov 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; 240 tools listable |
| Credentials demanded in prose | ✕gripforge_game_publish, gripforge_generate_district, gripforge_game_creation 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
3 of the 240 tools listed anonymously say in their own descriptions that they need an account or a key (gripforge_game_publish, gripforge_generate_district, gripforge_game_creation), 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.
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.
Neither the reserved <endpoint>/server-card location nor the domain's /.well-known/ai-catalog.json describes this endpoint (SEP-2127), so a client that discovers servers by domain will not find it.
