How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • Goes to the network for flight data through unofficial API access

This is third-party code. Review the repository files before installing.

What it does

Fli accesses Google Flights data through direct API requests, without HTML parsing or browser automation. It ships as an MCP server, a CLI and a Python library. The MCP server gives the agent two tools: search_flights looks up flights on a specific date with filters for airports, dates, cabin class and more, and search_dates finds the cheapest dates across a flexible range. The server runs over stdio with fli-mcp or over HTTP with fli-mcp-http. The repository also includes an fli skill and Python and TypeScript examples.

Who it is for. For people who want the agent to search and compare flights and find good dates.

Good fit when

  • You want the agent to find flights for a route and dates with filters
  • You want the cheapest departure dates in a range
  • You want flight data without scraping or a browser

Not a fit when

  • You need to book a ticket: Fli only searches and compares
  • You need carriers outside Google Flights coverage

Example request

Find flights from Moscow to Istanbul at the end of the month and show the cheapest dates

Limitations

Fli relies on unofficial access to the Google Flights API obtained through reverse engineering, so behavior may change when the service changes. The server only searches and compares flights; it does not book. Data is limited to what Google Flights returns.

How to disable. Remove the fli entry from the MCP client config and uninstall the flights package installed via pipx.

FAQ

Which tools does the server provide?

Two: search_flights looks up flights on a date with filters, and search_dates finds the cheapest dates in a range.

Can it run over HTTP?

Yes. fli-mcp-http serves over HTTP at http://127.0.0.1:8000/mcp/, while fli-mcp runs over stdio.
