The most feature-rich MCP server for Google Flights. 12 tools for search, price tracking, cabin comparison, emissions, layover analysis, and more. No API key required. The google mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 7 defined tools rather than through you.
Everything the assistant can do here goes through one of these:
lookup_airport — Search 8,800+ airports by city, name, IATA code, or countryfind_nearby_airports — Find alternative airports within a radius (default: 200km). Uses Haversine distanceSearch — The Search tool exposed by this serverUtility — The Utility tool exposed by this serverget_calendar_heatmap — Cheapest: $384 (2026-02-12) Most expensive: $870 (2026-04-13) Average: $632Reliability — The Reliability tool exposed by this serverDesign — See CLAUDE.md for architecture details and the Google Flights response format referenceThe server ships on npm as google-flights-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the database access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Google's toolset — lookup_airport, find_nearby_airports, Search and 4 more — is a fair guide to whether it matches your workflow. It is maintained by andreacappelletti97; worth a glance at recent repository activity before you build anything load-bearing on it.
