Variflight

You run an MCP server for Variflight that exposes flight information, weather, and comfort metrics through a consistent, scriptable interface. This lets you query flights, check weather, and monitor real-time data via simple tool calls, making it easy to integrate Variflight data into your apps and workflows.

How to use

To use this MCP server, connect your MCP client to the Variflight MCP endpoint you run locally or remotely. You will call named tools to retrieve flight data, weather forecasts, and comfort metrics. Each tool corresponds to a specific action, such as searching flights by departure and arrival, looking up a flight by its number, obtaining transfer options, checking the flight happiness index, locating an aircraft in real time, or retrieving a weather forecast for an airport.

How to install

Prerequisites: Node.js and npm or npx must be available on your system.

Create or update your MCP configuration to run the Variflight MCP server using npx and supply your Variflight API key.

        "VARIFLIGHT_API_KEY": "your_api_key_here"

Additional notes
