Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.

What the probe found
10 of the 16 tools listed anonymously say in their own descriptions that they need an account or a key (hello_agent, get_started, list_archetypes, alter_resolve_handle, register_autonomous_challenge, register_autonomous, describe_traits, describe_competencies, get_network_stats, alter_whoami), 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.
The server exposes a public surface before authorization: hello_agent, get_started, list_archetypes, alter_resolve_handle, alter_presence_read, register_autonomous_challenge, register_autonomous, describe_traits, describe_competencies, get_network_stats, recommend_tool, golden_thread_status, thread_census, alter_whoami, alter_login_status, alter_verify.
