Duffle MCP Server

This project is a Model Context Protocol (MCP) server that provides flight search and booking capabilities via the Duffel API. It exposes two tools: search_flights to find flight offers and book_flight to book flights using those offers.

Setup

Install Dependencies

npm install

Build the Project

npm run build

Run the Server

node build/index.js

You should see the message: Duffel MCP ready — search_flights · book_flight

Usage

The server implements two tools: • search_flights: Search for flight offers based on origin, destination, date, cabin class, and passenger count. • book_flight: Book a flight offer by providing offer ID and passenger details.

Search Example

Run the search script with optional parameters: origin, destination, date

node test/call-search.js [ORIGIN] [DESTINATION] [DATE]

Example:

node test/call-search.js SFO LAX 2025-06-15

This script will save the top offer ID to /tmp/offer_id.txt for booking.

Book Example

Run the booking script with optional passenger info:

node test/call-booking.js [NAME] [PHONE] [BORN_ON]

Example:

node test/call-booking.js "Ashmita Pandey" "+442080160508" "1990-01-01"

This script reads the saved offer ID from /tmp/offer_id.txt and attempts to book the flight.

Test Scripts

•	test/test-search.sh: Shell script to perform a flight search via FIFO pipes.
•	test/test-book.sh: Shell script to book a flight using a saved offer ID.

Ensure that the MCP server is running before using these scripts.
