fli

Why we included this project

Getting an AI assistant to answer real flight questions usually means building a scraper and hoping the page layout holds still. Fli sidesteps that by talking directly to Google Flights' internal API, reverse-engineered rather than scraped, and wraps the access in a Python library and CLI plus an MCP server you can point at Claude Desktop. The MCP side keeps things focused with two tools: one searches flights on a given date with filters for cabin class, stops, airlines, alliances, layover windows, and currency, while the other scans a flexible date range to surface the cheapest days. Setup is quick enough to try in an afternoon: pipx install flights, run fli-mcp, and connect the agent. Because it hits the API instead of the page, results come back faster and survive Google's UI changes, though the reverse-engineered endpoint means you should treat stability as a working assumption rather than a guarantee.
