Amadeus MCP Server

MCP-Amadeus is a community-developed Model Context Protocol (MCP) server that integrates with the Amadeus Flight Offers Search API to provide flight search capabilities through natural language interfaces. Built for use with MCP-compatible clients (e.g., Claude Desktop).

This project enables users to easily search for flight options between two locations with specific dates using the power of large language models (LLMs) and the Amadeus API.

This project uses the official amadeus-python SDK

🚀 Quick Start

Installing via Smithery

To install Amadeus MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @donghyun-chae/mcp-amadeus --client claude

1. Clone and Setup

git clone https://github.com/donghyun-chae/mcp-amadeus.git
cd mcp-amadeus-flight-offers

# Install dependencies (using uv or pip)
uv sync

2. Get Your API Key and Set Environment

cp .env.example .env

Then edit .env and add your API credentials:

AMADEUS_CLIENT_ID=your_client_id
AMADEUS_CLIENT_SECRET=your_client_secret
AMADEUS_HOSTNAME=test

Configuration Options:

• AMADEUS_CLIENT_ID: Your Amadeus API Client ID
• AMADEUS_CLIENT_SECRET: Your Amadeus API Client Secret
• AMADEUS_HOSTNAME: API endpoint to use - test for testing (default) or production for live API

Sign up on https://developers.amadeus.com/ and create an app to obtain your Client ID and Client Secret.

🌐 Environment Configuration

The server supports both test and production Amadeus API endpoints:

• Test Environment (AMADEUS_HOSTNAME=test): Use this for development and testing. The test environment provides:

  • Free API access with test data
  • No charges for API requests
  • Limited to test flight data

• Production Environment (AMADEUS_HOSTNAME=production): Use this for live applications. The production environment provides:

  • Real, live flight data
  • Pay-per-request pricing
  • Full access to all Amadeus services

⚠️ Important: Always use the test environment during development. Switch to production only when your application is ready for live data and you understand the associated costs.

3. Configure MCP Client

Register this server in your MCP client (e.g., Claude for Desktop).

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
    "mcpServers": {
        "amadeus": {
            "command": "/ABSOLUTE/PATH/TO/PARENT/FOLDER/uv",
            "args": [
                "--directory",
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/src/",
                "run",
                "--env-file",
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/.env",
                "server.py"
            ]
        }
    }
}

Replace /ABSOLUTE/PATH/TO/PARENT/FOLDER/ with the actual path to your project folder.

my case:

{
    "mcpServers": {
        "amadeus": {
            "command": "/Users/asena/.local/bin/uv",
            "args": [
                "--directory",
                "/Users/asena/mcp-amadeus/src/",
                "run",
                "--env-file",
                "/Users/asena/mcp-amadeus/.env",
                "server.py"
            ]
        }
    }
}
