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.

| Anonymous access | Handshake succeeds; 9 tools listable |
| Credentials demanded in prose | ✕navigate 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
1 of the 9 tools listed anonymously say in their own descriptions that they need an account or a key (navigate), 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.
The server exposes a public surface before authorization: navigate, act, search, live-search, route, execute, get_thread, show_ui, get_account.
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.
