What you can do with this MCP connector
You're gonna find real-time flight offers, book 'em, and manage your whole trip using your AI client. This server lets your agent handle everything, right in the chat. You can find flight options by kicking off an offer request, specifying where you're leaving, where you're headed, and how many people are going.
You'll get the flight possibilities, and you can then book a flight by providing your passenger details and choosing a specific offer. If you put an order on hold, you can process the payment using pay_for_flight_order. To check out your travel history, you can pull up a list of all your past and current flight bookings using list_flight_orders.
Need to know the basics? You can get a list of global airports with list_airports, a rundown of available airlines using list_airlines, or even check out what aircraft models are in use with list_aircraft.
How Duffel Flights MCP Works
- 1 Subscribe to the server and supply your Duffel Access Token.
- 2 Tell your agent the trip details (origin, destination, dates, etc.).
- 3 Your agent calls the necessary tools—for instance, first
create_flight_offer_request, thenlist_flight_offers, and finallycreate_flight_order—to handle the full booking process.
The bottom line is that your agent manages the entire, multi-step transaction using Duffel's APIs, letting you talk through your itinerary instead of running code.
Who Is Duffel Flights MCP For?
The corporate travel manager who spends hours clicking through booking portals to track company expenses, or the travel agent who needs to quote multiple clients on the fly. This server lets you manage company flight orders and client bookings without ever leaving your chat.
Oversees company flight orders and cross-checks airport metadata for compliance or reporting.
Quickly searches for multiple flight offers for several clients and manages their bookings using natural conversation.
Researches flight options and tracks reservation statuses without opening a separate booking website.
What Changes When You Connect
- Search for Options: Use
create_flight_offer_requestto pinpoint the best flight options based on origin, destination, and dates, getting multiple real-time offers in one go. - Finalize Bookings: Run
create_flight_orderto actually book the flight. You just supply the passenger details and select an offer, and the reservation is confirmed. - Manage Money: If you put a flight order on hold, use
pay_for_flight_orderto process the payment without leaving your agent. It handles the transaction directly. - Track Everything:
list_flight_ordersshows you every flight booking associated with your account. You get a clear view of your entire travel history. - Build Context: Use
list_airports,list_airlines, andlist_aircraftto look up specific IATA codes or check which planes an airline uses. This data helps refine complex searches.
Real-World Use Cases
Booking a multi-city business trip
A corporate travel manager needs to book a round-trip flight from Miami to Chicago, and then a one-way leg to Denver. Instead of opening three different booking forms, they tell their agent: 'Book me Miami to Chicago next week, then Denver the week after.' The agent calls create_flight_offer_request for the first leg, uses list_flight_offers to let the manager select the best option, and repeats the process for the second leg, finally calling create_flight_order to lock in all segments.
Checking a client's itinerary status
A travel agent needs to quickly verify if a client's flight to Paris is still active and hasn't been cancelled. They ask their agent to run list_flight_orders. The agent immediately pulls up the full booking details, confirming the status, which saves the agent from having to log into the external booking portal.
Finalizing a held booking
A user found a great flight deal but had to leave the chat before paying. They return and simply say, 'Pay for that flight order.' The agent knows which order is pending and calls pay_for_flight_order, completing the transaction instantly.
Researching airport codes for a new route
A user is planning a trip to a remote area and doesn't know the airport code. They ask their agent to run list_airports. The agent returns a list of major hubs, letting the user verify the exact IATA codes needed for the next search.
The Tradeoffs
Trying to search without dates
Just asking, 'What flights are available from London to Paris?' The system can't search without a date, and the user is left with a dead end, forced to guess or start over.
→
Always provide origin, destination, and dates. Use create_flight_offer_request with all required parameters to get a meaningful search result.
Confusing 'offer' with 'booking'
Thinking that listing flight offers (list_flight_offers) automatically reserves the seat. It doesn't; it just shows you what's available. You must run create_flight_order to actually book it.
→
After reviewing offers using list_flight_offers, you must explicitly tell your agent to book it. That action requires create_flight_order and passenger data.
Forgetting to pay for held orders
Finding the perfect flight, getting an offer, but forgetting to pay and letting the hold expire. The booking falls apart, and you have to start the search all over.
→
If you use create_flight_offer_request and the order is put on hold, use pay_for_flight_order as soon as possible to lock in the reservation.
When It Fits, When It Doesn't
Use this if you need to manage the full lifecycle of a trip: finding available flights, securing the booking, and paying for it. You need an agent that handles multi-step data dependency. Don't use this if you just need general flight information or airport codes—those are handled by separate directory tools. Don't use this if you need to manage flights for a non-travel domain (e.g., shipping or inventory)—it only handles air travel. If your process requires finding offers (create_flight_offer_request) and then confirming the reservation (create_flight_order), this is the right toolset.

Available Capabilities
Manually booking flights means juggling multiple tabs and forms.
Today, booking a complex trip means opening a browser, finding the departure page, filling out the origin and destination, selecting dates, and then repeating that whole process for every single leg of the journey. You're copying data from one tab to the next, waiting for the page to reload, and hoping you didn't miss a required field. It's tedious, and you're prone to data entry errors.
With the Duffel Flights MCP Server, you just talk to your agent. You tell it, 'Book me from LAX to JFK next Tuesday.' Your agent handles the search, the option filtering, and the booking structure in the background. You get the final, confirmed itinerary, without ever touching a booking form.
Duffel Flights MCP Server: Book and Pay from Chat
The whole sequence of listing offers, selecting the right flight, and then submitting the payment details used to take several minutes of manual clicking and form filling. This meant pausing the conversation to go check a payment gateway or cross-reference an airport code.
Now, the agent manages the state. It runs `list_flight_offers` to show you the options, then it runs `create_flight_order` and handles the payment via `pay_for_flight_order`—all in one fluid conversation. The process is complete, and you don't leave the chat.
