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 22 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

What the probe found

warningTools needing credentials are listed without a challenge

10 of the 27 tools listed anonymously say in their own descriptions that they need an account or a key (embed_text, get_field_orientation, save_paper, unsave_paper, list_library, list_collections, list_watches, find_gaps, ask_library, check_drift), 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.

27 tools usable without signing in
