A Model Context Protocol server that creates travel agent-level flight plans using the fast-flights API.
Google Flights MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Google Flights MCP directly instead of describing what you should do. A Model Context Protocol server that creates travel agent-level flight plans using the fast-flights API.
Once Google Flights MCP is connected, these are the calls the assistant has available:
search_one_way_flights — Search for one-way flights between airportssearch_round_trip_flights — Search for round-trip flights between airportscreate_travel_plan — Generate a comprehensive travel plan@modelcontextprotocol/inspector on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
You will need one environment variable: PYTHONPATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Google Flights MCP's toolset — search_one_way_flights, search_round_trip_flights, create_travel_plan — is a fair guide to whether it matches your workflow. It is maintained by salamentic; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
