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.

| Anonymous access | Handshake succeeds; 14 tools listable |
What the probe found
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.
