Perplexity

Direct flight search in your workspace

The `create_flight_offer_request` tool initiates live flight searches across global airlines directly from your chat sidebar. Your agent executes this search and uses `list_flight_offers` to display pricing, schedules, and layover details. Having this capability in your editor makes it simple to plan team travel or test booking interfaces. The agent formats the flight options in clean Markdown tables so you can compare itineraries without leaving your workspace.

Book seats using this MCP Server

The `create_flight_order` tool handles the passenger registration process, securing your seats with the airline. Your agent passes the passenger details to Duffel to create a held booking, which reserves the pricing while you review the details. If you need to manage existing bookings, the agent uses `list_flight_orders` to pull your active reservations. This lets you check flight statuses and booking references directly within your terminal or chat panel.

Process payments and look up flight metadata

The `pay_for_flight_order` tool executes payments for pending bookings to finalize your tickets. Your agent calls this tool to process the transaction securely, ensuring your seats are issued and confirmed. To make searches more accurate, the MCP Server uses `list_airports`, `list_airlines`, and `list_aircraft` to resolve names and codes. This metadata matching ensures your queries are clean and error-free before you book.
