Added "book_hotel_v2", "compare_rates_v2" and "get_hotel_details_v2" (43 tools before, 46 now)
Book a hotel room using a rate from get_hotel_rates. Requires guest details and a saved payment method. Use get_payment_methods to find the payment ID. The gondola_rate_id comes from the room rates returned by get_hotel_rates. Returns a versioned structured result for MCP Apps.
Compare current canonical cash vs points rates side-by-side for one or more hotels. Use this whenever the user is making a cash-vs-points decision — whether focused on a single hotel ("compare cash and points at Park Hyatt Tokyo") or weighing top picks against each other ("which of these is the best points redemption?"). Pass an array of one to five hotel_ids resolved from search_hotels. Returns current cash rate, points rate, CPP valuation, and deal scores per hotel; a hotel whose current pricing has not loaded is labeled unconfirmed, not unavailable.

Content only, with no dates or availability. Long lists are capped and end with a '+N more' count, so an amenity missing here may still exist.

Save a learned travel preference or experience to the user's traveler profile. Use when the user shares preferences, likes, dislikes, or trip experiences that should inform future recommendations. Examples: 'Prefers boutique hotels over chains', 'Always takes a window seat', 'Vegetarian — recommend plant-based restaurants', 'Hated ground floor rooms'. Don't save temporary logistics like 'my flight lands at 3pm'. Entries are appended, so saving one preference never overwrites another.

Get the hotels the user has saved as favorites in Gondola, newest first. Use this when the user asks about their favorite or saved hotels, or to ground recommendations in places they already like. Returns each hotel's name, hotel_id, chain, address, and the date it was saved. Pass the returned hotel_id to get_hotel_details or get_hotel_rates. When more favorites exist, the result includes a cursor; pass it back to fetch the next page.

Added "book_flight", "cancel_flight_booking", "get_flight_booking" and 1 more (39 tools before, 43 now)
Book a prepared flight only after the traveler explicitly confirms the exact current quote, total, currency, and consent version. Use the handoff_id and quote_id returned by prepare_flight_booking and a saved payment_id from get_payment_methods. Gondola derives the traveler ID and type and a stable booking request ID; do not invent or retry with different identities. If the outcome is uncertain, retrieve the booking state instead of repeating the mutation.
Preview flight cancellation first with confirm=false or omitted. Show the returned itinerary cancellation scope and exact terms before asking the traveler to confirm. To confirm, send the same booking_id plus the preview's cancellation_id, currency, and expected_refund_amount with confirm=true; when the preview has no verified refund amount, represent that nullable amount by leaving expected_refund_amount omitted. Itinerary cancellation and refund settlement are separate states: a cancelled itinerary does not by itself mean the ticket refund or customer payout completed. If the outcome is unc…
Get the current owner-scoped state of a Gondola flight booking, including booking, payment, ticketing, action-required, cancellation, refund-review, failure, and chronology state. Use this after book_flight or when a booking mutation had an uncertain outcome; retrieving status does not repeat the booking.

Prepare a flight for booking from a signed selection_token that comes only from an eligible search_flights row. Search re-shops the selected itinerary instead of trusting a provider-native offer, then returns its current internal booking or referral capability, including any reconfirmation or unavailable state. This call does not book or charge the traveler.
