Fli (Google Flights search)

listing.about

Fli is a Python library, CLI and MCP server that queries Google Flights data directly through its internal API instead of scraping pages. The MCP server offers flight search for a specific date and a cheapest-dates search over a date range. Filters include cabin class, stops, airlines, alliances, layover length, departure window, currency, language and country.

It runs locally over stdio with uvx (uvx --from flights fli-mcp), or over streamable HTTP with fli-mcp-http, which serves at http://127.0.0.1:8000/mcp/. No sign-in or API key is needed. This is a community project and is not affiliated with Google.
