Google Flights MCP server by HasData: fares, flight legs, carbon emissions and price history, as JSON.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
A hosted Model Context Protocol (MCP) server that gives Claude, Cursor, Windsurf and any other MCP client one Google Flights tool. Search one-way, round-trip and multi-city itineraries with fares, flight legs, carbon emissions and price history, all as structured JSON, with no Google account and no retired travel API to work around.
1,000 free credits every month, no card required, which is about 66 flight searches.
