Google Flights

This connects Claude to Google Flights data without requiring an API key. You get 12 tools covering flight search, multi-city itineraries, price tracking with SQLite persistence, calendar heatmaps showing 60 days of daily prices, cabin class comparisons, and nearby airport suggestions. Each result includes CO2 emissions per leg, Google's own price context (low/typical/high), aircraft details, seat pitch, and direct booking URLs. The price tracking persists locally and reports trends across observations. It reverse engineers Google's internal FlightsFrontendService endpoint with caching, retry logic, and circuit breakers to handle rate limits. Reach for this when you need real flight data in Claude without managing API credentials or building scrapers yourself.
