The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
activate_notification_integrationadd_notification_email_bcccancel_ordercheck_order_cancellationCheck if a booking can be cancelled and what the refund/penalty/deadline are. Always call this before cancel_order. Speak about 'the booking' and 'cancellation rules' to the user — never quote internal labels, REST routes, or error codes.
check_order_modificationCheck if a booking can be changed and what kinds of change are allowed (contact info, passport, rebook, baggage). Always call this before modify_order. Speak about 'the booking' and 'allowed changes' to the user — never quote internal labels, REST routes, or error codes.
contact_travelerscreate_orderdelete_notification_email_bccdisconnect_notification_integrationget_active_risk_alertsget_advisoriesget_airport_delay_statsGet current delay statistics for an airport on a specific date. Shows average departure/arrival delays and cancellation rates. Use this during weather events or disruptions to assess the situation at an airport.
get_airport_flightsGet the departure or arrival board for an airport within a time window (max 12 hours). Shows all flights with their status, terminals, and gates. Use this to monitor departures/arrivals or check for widespread delays.
get_airportGet detailed information about a specific airport or city by its IATA code. Returns name, city, and country.
get_clientGet full details of a saved traveler — passport documents and loyalty memberships needed for booking. Typical flow: search_clients → pick the right person → this tool → create_order. Speak about 'this traveler', 'their passport', 'their loyalty programs' to the user; never quote internal labels, RES…
get_conflictsget_country_advisoryget_country_risk_scoreget_current_userget_flight_delay_statsGet historical delay statistics for a specific flight number. Shows how often the flight is delayed, average delay duration, and reliability assessment. Use this to evaluate a flight's punctuality before booking.
get_flight_resultsRetrieve or filter existing flight search results using a cache ID from a previous search. Apply filters (direct flights, specific airlines, price range), change sorting, or paginate through results without running a new search. Cache expires after ~15 minutes. If the originating search_flights call…
get_flight_statusGet real-time status of a specific flight by flight number and date. Returns departure/arrival times (scheduled, actual, estimated), terminals, gates, aircraft info, and delay information. Use this to check if a flight is on time, delayed, or cancelled.
get_hotel_locationGet hotel location details by ID. Returns name and entity type (city, region, hotel).
get_hotel_offersget_main_clientget_notification_settingget_orderGet full details of a booking — travelers, services, tickets, and payment status. Speak about 'the booking' to the user; never quote internal labels, REST routes, or error codes.
get_rate_guard_settingsget_risk_alerts_by_countryget_slack_install_urlget_slack_statusget_telegram_statusget_traveler_preferencesget_travelerGet full details of a single traveler — passport, nationality, current trip with services (hotels, flights). Typical flow: search_travelers → pick a person → this tool. Speak in plain language ('this traveler', 'their passport'); never quote internal labels, REST routes, or error codes.
init_telegram_linklist_notification_email_bcclist_notification_integrationslist_notification_settingslist_ordersList the user's bookings with optional filtering by status, booking reference, traveler name, or date range. Supports paging and sorting. Speak in plain language to the user — never quote internal labels, REST routes, or error codes.
list_target_companiesList the legal-entity companies attached to a user, for admin impersonation. Call this when another tool tells you the target user has multiple companies and you need to pick one before retrying.
modify_orderChange an existing booking: contact info, passport, dates (rebook), or add baggage. Always call check_order_modification first to learn which changes are allowed for this booking. Modification is asynchronous — use get_order afterwards to confirm the result. Speak about 'the booking' and 'the change…
search_airlinesSearch for airlines by name or IATA code. Returns matching airlines with their codes and names. Use this to find airline codes for filtering flight searches.
search_airportsSearch for airports by name, city, or IATA code. Returns a list of matching airports and cities with their codes. Use this to find airport codes before searching for flights.
search_clientssearch_flightssearch_hotel_locationsSearch for hotel locations (cities, regions, hotels) by name. Returns location IDs needed for hotel search.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
51/51 tools missing one or more hints — activate_notification_integration (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add_notification_email_bcc (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cancel_order (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +48 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/23 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 9/51 tools referenced in tests (18%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
