`duffel_flight_search`

Pack: duffel · Endpoint: https://gateway.pipeworx.io/duffel/mcp

Search flights (with pricing) from to on — returns the 5 cheapest real, bookable offers from the Duffel Flights API, each with total price, airline, and per-segment flight numbers/times. Pass return_date for a round trip. This is REAL flight inventory: use a Duffel test token (duffel_test_…) for sandbox results. Example: duffel_flight_search({ origin: “JFK”, destination: “LHR”, departure_date: “2026-08-15”, passengers: 2, cabin_class: “economy”, apiKey: “duffel_test…” })
