Scored across 9 tools
Each tool has a clearly distinct purpose: search_flights and search_multi_city handle different search modes, get_return_flights advances itineraries, get_booking_options retrieves booking providers, and the price-tracking tools (track, list, untrack, check, get_history) cover the full watch lifecycle without overlap.
All tool names follow a consistent verb_noun snake_case pattern, such as search_flights, track_price, get_price_history, and untrack_price. Verb choices are appropriate and parallel (track/untrack, get/list/check), making the set predictable and easy to navigate.
Nine tools is well-scoped for the server's purpose of flight search and price tracking. Every tool serves a clear need, and there is no bloat or redundancy.
The tool surface covers the entire flight discovery flow (search, multi-city, return options, booking) and price watch CRUD operations. The only minor gap is the lack of an update operation for an existing price watch, but users can untrack and re-track to adjust targets, so it is easily worked around.
