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 13 tools listed anonymously say in their own descriptions that they need an account or a key (ping), 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: ping, get_dataset_stats, get_unusual_activity, get_symbol_flow, get_top_prints, get_flow_history, get_flow_streaks, get_expiry_concentration, get_flow_sentiment, get_iv_rank, get_oi_changes, get_sector_flow, get_market_regime.
