    Server tool list (8)

    Raw names from tools/list. Only developers need these.

    search_hotelsSearch hotels by location and dates for exactly one room, with check-in up to 340 days from today. Returns available properties with nightly rates across major brands, boutique, and independent hotels. The first 1Stay release supports one room per search and reservation. Guest pays the hotel directly. Hotel's own confirmation number. Loyalty points apply.
    get_hotel_detailsGet rates and room details for exactly one room at a specific hotel. Returns room types, live rates, amenities, cancellation policies, and rate_codes required by book_hotel. Guest pays the hotel directly. Displayed totals include taxes and any applicable, itemized 1Stay Booking Fee. Loyalty points eligible. Room type notes: "Run of house" means the hotel assigns the room at check-in. "Suite" at select-service brands usually means a larger room with a sofa, not a separate bedroom. Non-refundable rates are cheaper but cannot be changed or canceled.
    book_hotelBook exactly one hotel room. The first 1Stay release does not support multi-room searches or reservations. Returns a secure checkout URL. This tool accepts no guest identity or payment fields. Name, email, phone, and payment details are collected on the secure checkout page. Guest pays the hotel directly. Their credit card statement shows the hotel name, not 1Stay. Hotel's own confirmation number. Loyalty points apply automatically. The displayed total includes taxes and any applicable, itemized 1Stay Booking Fee. Requires a rate_code from get_hotel_details, valid approximately 15 minutes. Expired codes are rejected.
    lookup_bookingLook up a reservation by verifying the guest's identity. Returns the confirmation number and booking summary in conversation. Requires the guest's full name plus either the hotel confirmation number, or the last 4 digits of the card used to book together with the check-in date. An email address is not a verification factor. It may be supplied in addition and will be matched, but a name and an email alone will not return a reservation.
    resend_confirmationResend a hotel reservation confirmation email. Use either the confirmation number from a successful lookup_booking call, or the guest's full name and email address when they do not know their confirmation number, card last four, or check-in date. The email contains the hotel confirmation number the guest can then use with lookup_booking or cancel_booking. Recovery requests never reveal whether a reservation matched. The confirmation is sent only to the email address already on the booking record; there is no recipient override. Email changes are handled at https://stayker.com/service.
    get_bookingLook up a reservation exclusively by the hotel confirmation number shown in the guest's confirmation email. Internal Stayker booking IDs are never accepted or disclosed by MCP. Returns full booking details including hotel, dates, guest info, rate, and status. Anonymous access requires a verification_token issued by lookup_booking and scoped to a single booking. Without a valid token, no booking data is returned. Developers authenticated with their own API key do not need a token; their access is scoped to their own bookings.
    cancel_bookingCreate a secure cancellation handoff for a hotel reservation. After verifying the guest, this tool returns the hotel cancellation policy on file and a first-party 1Stay cancellation URL. It never cancels the reservation in conversation. The guest must open the secure page, review the policy, and explicitly confirm there. 1Stay does not estimate a refund, credit, penalty, or amount the hotel may charge. Until that page reports success, the reservation is NOT cancelled. A successful cancellation is confirmed on the page and by email to the address on file.
    search_toolsList available 1Stay hotel booking tools. An optional keyword filters by search, book, cancel, or details; absence of a keyword returns all tools.
