What the probe found

warningTools needing credentials are listed without a challenge

6 of the 13 tools listed anonymously say in their own descriptions that they need an account or a key (hemmabo_booking_create, hemmabo_booking_negotiate, hemmabo_booking_checkout, hemmabo_booking_cancel, hemmabo_booking_status, hemmabo_booking_reschedule), 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.

13 tools usable without signing in

The server exposes a public surface before authorization: hemmabo_search_properties, hemmabo_search_availability, hemmabo_booking_quote, hemmabo_booking_create, hemmabo_booking_negotiate, hemmabo_booking_checkout, hemmabo_booking_cancel, hemmabo_booking_status, hemmabo_booking_reschedule, hemmabo_host_readiness_check, hemmabo_host_onboarding_link, verify_vacation_rental_node, get_verified_stay_offer.
