What the probe found

warningTools needing credentials are listed without a challenge

1 of the 9 tools listed anonymously say in their own descriptions that they need an account or a key (buy_credits), 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.

9 tools usable without signing in

The server exposes a public surface before authorization: check_ground_motion, check_portfolio, get_coverage, get_motion_history, get_account, register_agent, buy_credits, ask_inspector, get_usage.
