How to Set Up and Use Flight Search Tool
The mcp-flight-search server provides real-time flight search capabilities to AI assistants by integrating with the SerpAPI Google Flights endpoint. It exposes a search_flights_tool that accepts origin and destination airport codes, outbound date, and an optional return date for round-trips, returning flight options with carrier, price, stop count, and duration. Developers and travel planners use it to let Claude answer natural language flight queries without requiring users to navigate booking websites.
Prerequisites
- Python 3.8 or higher
- A SerpAPI account and API key (SERP_API_KEY) — free tier available at serpapi.com
- pip or uv for package installation
- An MCP client such as Claude Desktop or Claude Code
Get a SerpAPI key
Sign up at https://serpapi.com to get an API key. The free tier provides 100 searches per month. The SERP_API_KEY is required — the server will not start without it.
Install mcp-flight-search via pip
Install the package from PyPI. This installs the MCP server and all dependencies including the SerpAPI client.
pip install mcp-flight-searchSet the SerpAPI key environment variable
Export the SERP_API_KEY environment variable, or add it to the env block in your MCP client configuration.
export SERP_API_KEY="your_serpapi_key_here"Add mcp-flight-search to Claude Desktop configuration
Edit your claude_desktop_config.json to add the flight search server. Set the SERP_API_KEY in the env block so it is available when Claude Desktop launches the server.
Restart Claude Desktop and test a flight search
Restart Claude Desktop and ask it to search for flights. Use IATA airport codes (JFK, LAX, LHR, etc.) and specify the date in YYYY-MM-DD format for best results.
Flight Search Tool Examples
Client configuration
Add mcp-flight-search to your claude_desktop_config.json. The SERP_API_KEY is required in the env block.

Use these prompts to search for flights through Claude. Use IATA codes for airports and YYYY-MM-DD format for dates for most accurate results.
- "Find flights from JFK to LAX on 2026-08-15"
- "Search for round-trip flights from ATL to ORD departing 2026-09-01 and returning 2026-09-08"
- "What are the cheapest flights from LHR to JFK next month?"
- "Find non-stop flights from SFO to SEA for next Friday"
- "Compare flight options from NYC to Miami for the weekend, show prices and durations"Troubleshooting Flight Search Tool
Search returns no results or 'invalid API key' error
Verify the SERP_API_KEY is valid by testing it directly at https://serpapi.com/playground. Ensure the key is copied without extra spaces. Check your SerpAPI account for remaining credits — the free tier has a 100 search/month limit.
Flight search returns results but dates or airports seem wrong
Use standard IATA airport codes (JFK, not 'New York') and YYYY-MM-DD date format. The server passes these directly to SerpAPI Google Flights. Avoid city names or informal airport names which may not resolve correctly.
Server fails to start with ModuleNotFoundError
Ensure mcp-flight-search is installed in the same Python environment used by Claude Desktop. If you have multiple Python versions, use the full path to pip: '/path/to/python -m pip install mcp-flight-search'. Alternatively, use uvx to run it in an isolated environment.
