CHEAP_FLIGHTS_MCP
Built on FastMCP, this server queries RyanAir, WizzAir, and Google Flights in parallel using asyncio.gather to find cheap flights in real time. It exposes five tools: search_flights for querying routes with dates and passenger counts, get_destinations for listing available routes from an airport, and three tools for managing which airlines are active in your search. Results include direct booking links to airline sites. The implementation uses exponential backoff retries for rate-limited APIs and includes currency conversion for Google Flights results. You get a Flask web UI and a Claude-powered conversational agent on top of the MCP server, but the core flight search works standalone without any API keys.
