What the probe found

warningTools needing credentials are listed without a challenge

2 of the 10 tools listed anonymously say in their own descriptions that they need an account or a key (create_checkout, my_esims), 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.

No CORS headers for browser-based clients

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.

10 tools usable without signing in

The server exposes a public surface before authorization: search_esim_plans, get_plan_details, create_checkout, get_order_status, my_esims, list_esim_topups, topup_esim, my_orders, check_destination_coverage, find_cheapest_plan.
