Book Flights with AI (FlightClaw)

Book flights with AI from your assistant. FlightClaw is an AI flight booking agent and MCP server: it searches about 300 airlines for cheap flights, opens a secure checkout and returns the airline booking reference. The traveler pays on a hosted page or with a Link virtual card. The agent never handles card numbers.

When to use

• The user asks to find, compare or book a flight.
• The user picked an offer and wants to pay for it.
• The user wants a seat map before buying.

Prerequisites

Connect the FlightClaw hosted MCP server: https://mcp.flightclaw.com/mcp (streamable HTTP, OAuth sign-in). Nothing to install.

• Claude Code: claude mcp add --transport http flightclaw https://mcp.flightclaw.com/mcp
• Cursor: One-click install, or add {"mcpServers":{"flightclaw":{"url":"https://mcp.flightclaw.com/mcp"}}} to ~/.cursor/mcp.json
• VS Code: One-click install, or code --add-mcp '{"name":"flightclaw","type":"http","url":"https://mcp.flightclaw.com/mcp"}'
• Claude (web / desktop): Settings > Connectors > Add custom connector > paste https://mcp.flightclaw.com/mcp
• ChatGPT: Settings > Apps & Connectors > Create (developer mode) > paste https://mcp.flightclaw.com/mcp

If the FlightClaw tools are not available, ask the user to connect the server first.

Tool flow

1. Search. Call search_flights with origin, destination (IATA codes), date (YYYY-MM-DD) and optional return_date, cabin, adults, children, infants, passenger_ages, max_connections, limit.
   • For a ranked shortlist that uses the user's saved preferences, call recommend_flights instead (same route fields). It returns the top 3 offers with reasons.
   • For more than one leg, call search_multi_city with slices (see the plan-group-trip skill).
2. Check the offer. Call get_offer with the chosen offer_id. Confirm price, bags and fare rules. Offers expire in about 30 minutes; search again if one has expired.
3. Seat map (optional). Call get_seat_map with offer_id. This is information only. Checkout does not sell seats.
4. Passengers. Call list_travelers to find saved traveler names. Save new travelers with save_traveler (see the traveler-profile skill).
5. Confirm with the user. Show the route, times, airline, fare rules and the total price including the fee. Get an explicit yes.
6. Create checkout. Call create_checkout with offer_id and passengers (an array of saved traveler names or passenger objects). It returns checkout_id, checkout_url, total_amount and total_currency. Nothing is charged yet.
7. Pay. Use one of two ways:
   • Checkout link: send checkout_url to the traveler. The traveler pays there by card.
   • Link virtual card: create a Link spend request for exactly total_amount in total_currency. The user approves it in Link. Pay on checkout_url with the Link virtual card. Never pay more than the approved amount.
8. Wait for completion. Call get_checkout_status with checkout_id until the status is completed.
9. Confirm the booking. Call get_order with the order id to get the booking reference. Optionally call log_trip to save the trip in history.

Price and fee

• total_amount from search, get_offer and create_checkout already includes the FlightClaw booking fee: 5% + $3, minimum $12.
• Always show the total including the fee. Do not add the fee again.
• The price comes from the airline at checkout time, not from the caller.

Rules

• Never ask for or accept card numbers in chat.
• Always get explicit user confirmation before create_checkout.
• Show the exact total_amount and total_currency before payment.
• With a Link virtual card, the spend request must equal total_amount. Never more.
• Do not say a flight is booked until get_checkout_status is completed and get_order returns a booking reference.
• Search is limited to 100 searches per user per UTC day. Avoid repeated searches.

Example prompts

• "Book me the cheapest nonstop flight from London to New York on 12 March."
• "Find business class flights LHR to SFO next Friday and book the best one for me."
• "Show me the seat map for that BA flight before I pay."
• "Book a return flight to Lisbon for two adults, 4 to 9 June."
• "Pay for this flight with my Link card."
