Amadeus MCP Server

This is a Model Context Protocol (MCP) server that connects to the Amadeus API to provide flight search, booking, and analysis capabilities for AI assistants.

Features

Flight Search: Find flights between airports with various parameters
Airport Information: Search for airports by keyword, city, or country
Price Analysis: Get price metrics for routes to determine if current prices are high or low
Cheapest Dates: Find the most economical dates to travel
Flight Details: Get detailed information about specific flight offers

Prompts

The server provides several pre-configured prompts for common travel planning scenarios:

Analyze Flight Prices (analyze-flight-prices): Analyze flight prices for a route with insights on pricing trends
Find Best Deals (find-best-deals): Find the best flight deals for a specific route and date
Plan Multi-City Trip (plan-multi-city-trip): Plan a complete multi-city itinerary with optimal routing
Find Cheapest Travel Dates (find-cheapest-travel-dates): Identify the most economical dates to travel

Setup

Prerequisites

Node.js 16.x or higher
Amadeus API credentials (Client ID and Secret)

Installation

Clone the repository:

git clone https://github.com/yourusername/amadeus-mcp-server.git
cd amadeus-mcp-server

Install dependencies:

npm install

Create a .env file in the root directory with your Amadeus API credentials:

AMADEUS_CLIENT_ID=your_client_id
AMADEUS_CLIENT_SECRET=your_client_secret

Running the Server

Build and start the server:

npm run build
npm start

For development:

npm run dev

Testing and Development

This project uses Jest for testing and Biome for linting and formatting.

Run unit tests:

npx jest

Run tests with watch mode:

npx jest --watch

Run tests with coverage:

npx jest --coverage

Run integration tests (requires Amadeus API credentials):

npm run test:integration

Run linting:

npm run lint

Format code:

npm run format

Integration Testing

The project includes comprehensive integration tests that verify the server's interaction with the real Amadeus API. These tests help ensure that our API clients work correctly with the actual API endpoints and handle responses appropriately.

Requirements for Integration Tests

Amadeus API Credentials: Tests require valid Amadeus API credentials in the .env file:
```
AMADEUS_CLIENT_ID=your_client_id
AMADEUS_CLIENT_SECRET=your_client_secret
```
Test Environment: Tests are configured to use the Amadeus Test Environment, not the production API.

Running Integration Tests

npm run test:integration

The integration tests are located in __tests__/integration and validate the following API features:

Airport Search: Searching for airports by code or keyword
Flight Search: Finding flights for one-way and round-trip journeys
Price Analysis: Getting price metrics for specific routes

Best Practices for Integration Testing

API Rate Limits: The tests include automatic rate limit handling with exponential backoff to avoid API throttling. When running tests frequently, you may still encounter rate limits.
Conditional Testing: Tests are designed to skip automatically if API credentials are missing, allowing the test suite to run without errors in environments without credentials.
Test in Isolation: When developing a new feature, you can run specific test files:
```
npx jest __tests__/integration/flight-search.test.js
```
Longer Timeouts: Integration tests use longer timeouts (60 seconds) to accommodate network latency and retries.
Mock for CI/CD: For continuous integration pipelines where real API access isn't available, use __tests__/amadeus-mock.test.js which runs without actual API calls.

Integration

To use this MCP server with OpenAI's Assistant API or other compatible AI systems, configure the assistant to connect to this server's endpoint.

Tools

The server provides the following tools:

`search-flights`

Search for flight offers between two locations.

`search-airports`

Search for airports by keyword, city name, or IATA code.

`flight-price-analysis`

Get price metrics for a flight route to determine if current prices are high or low.

`get-flight-details`

Get detailed information about a specific flight offer.

`find-cheapest-dates`

Find the cheapest dates to fly for a given route.

Resources

The server provides schema resources for:

Flight offers (schema://flight-offers)
Airports (schema://airports)
