Variflight MCP server

Variflight MCP Server is an implementation of the Model Context Protocol that provides tools for accessing flight information, weather data, and comfort metrics through Variflight's services. It allows you to search for flights, get transfer information, track aircraft locations, and check airport weather forecasts.

Getting Started

Before using the Variflight MCP server, you'll need to obtain an API key from Variflight's MCP platform.

Installation

To install and configure the Variflight MCP server, add the following configuration to your MCP configuration file:

{
    "mcpServers": {
        "variflight": {
            "command": "npx",
            "args": [
                "-y",
                "@variflight-ai/variflight-mcp"
            ],
            "env": {
                "VARIFLIGHT_API_KEY": "your_api_key_here"
            }
        }
    }
}

Make sure to replace your_api_key_here with your actual Variflight API key.

Using the Available Tools

Search Flights by Departure and Arrival

searchFlightsByDepArr({
  dep: "PEK",  // Beijing
  arr: "SHA",  // Shanghai
  date: "2024-03-20"
})

Search Flights by Number

Look up flight information using a specific flight number:

searchFlightsByNumber({
  fnum: "MU2157",
  date: "2024-03-20"
})

Get Flight Transfer Information

Find transfer options between cities:

getFlightTransferInfo({
  depcity: "BJS",
  arrcity: "LAX",
  depdate: "2024-03-20"
})

Flight Happiness Index

Retrieve detailed flight comfort metrics:

flightHappinessIndex({
  fnum: "MU2157",
  date: "2024-03-20"
})

Real-time Aircraft Location

Track an aircraft's location using its registration number:

getRealtimeLocationByAnum({
  anum: "B2021"
})

Airport Weather Forecast

Get a 3-day weather forecast for specific airports:

getFutureWeatherByAirport({
  airport: "PEK"
})

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
