What is the Google MCP Server?

The most feature-rich MCP server for Google Flights. 12 tools for search, price tracking, cabin comparison, emissions, layover analysis, and more. No API key

What it actually does

  • Carbon emissions — per flight and per leg (CO2 in kg)
  • Price context — Google's own assessment of whether a price is low, typical, or high
  • Price tracking — track prices over time with SQLite persistence, detect drops and trends
  • Calendar heatmap — 60 days of daily prices in a single API call
  • Cabin class comparison — economy vs premium vs business vs first, side by side
  • Nearby airport suggestions — find cheaper alternatives (e.g., EWR/LGA near JFK)
