Google Flights MCP Server

A Model Context Protocol (MCP) server implementation that connects your Agents or LLMs to Google Flights data. Access flight information, find the cheapest options, filter by time restrictions, and get Google Flights' best recommendations!

🌍 Overview

This MCP server provides seamless access to Google Flights data, enabling your AI agents to:

• Retrieve Comprehensive Flight Info
• Find the Cheapest Available Flights
• Filter flights based on Specific Time Constraints
• Get Google Flights' recommended Best Flights

Note: Currently, this tool only does one-ways (if you ask for a round-trip, it'll do two one-ways though!) as I built it as a fun pet project to learn about MCPs.

If anyone actually finds this useful or wants me to, I can work on adding Round-Trip and Multi-City functionality!! Just raise a PR or hit me up!

🎥 Usage & Demo

Just follow the Quick Start to set this up for Claude Desktop, Cursor, or another MCP Client and just ask away to find out about your desired flight info!!
