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
1 of the 17 tools listed anonymously say in their own descriptions that they need an account or a key (start_eligibility_check), 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: check_upgrade_eligibility, start_eligibility_check, mint_eligibility_session, get_eligibility_result, place_bid, modify_bid, get_bid_status, predict_bid_success, start_watch, get_watch_status, ask_upgrade_agent, partner_question_insights, usage_totals, list_partners, get_partner_info, get_upgrade_pricing, search_upgrade_options.
