Found a link to an MCP server for Google Flights (github.com/punitarani/fli), went to test it. Connected to Claude, typed: "find me flights BCN→BER for April, nonstop, under 100 euros." Claude searches, filters, and sorts by price on its own.
!Flight search results via MCP
Two tools inside: flight search for a specific date, and cheapest-date search across a range. The second one is more useful — "when is the cheapest time to fly Berlin to Barcelona in April."
It doesn't work via scraping or computer use where AI clumsily clicks around the screen. The author reverse-engineered the protocol Google Flights uses to talk to its backend and calls it directly. So it works fast and doesn't break on every redesign.
Install with one command: `pipx install flights`.
