Search Google Flights and find the cheapest travel dates via chat

Connects to Google Flights via the fli MCP tool (no scraping — direct API access through reverse engineering). Searches one-way or round-trip flights with full filter support: cabin class, stops, departure time window, airline preference, and sort order. Can also scan a flexible date range to surface the cheapest travel days, making it easy to optimize for price without manually checking every date on Google Flights.

Install the MCP server once with pipx install flights, then run fli-mcp and connect it to the agent. After that, just ask in plain English.
