Windows Terminal MCP server

This MCP server provides programmatic access to the Windows terminal, allowing AI models to interact with the Windows command line interface through a set of standardized tools. The server enables executing commands, reading terminal output, and sending control signals to the terminal.

Installation

Clone the Repository

git clone https://github.com/capecoma/winterm-mcp.git
cd winterm-mcp

Install Dependencies

npm install

Build the Project

npm run build

Configure Claude Desktop

Add the server configuration to %APPDATA%/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "github.com/capecoma/winterm-mcp": {
      "command": "node",
      "args": ["path/to/build/index.js"],
      "disabled": false,
      "autoApprove": []
    }
  }
}

Note: Replace "path/to/build/index.js" with the actual path to your built index.js file.

Usage

The WinTerm MCP server provides three main tools for interacting with the Windows terminal:

Write to Terminal

Executes commands or writes text to the Windows terminal:

{
  "command": "echo Hello, World!"
}

Read Terminal Output

Retrieves a specified number of lines from previous terminal output:

{
  "linesOfOutput": 5
}

Send Control Character

Sends a control signal (such as Ctrl+C) to the terminal:

{
  "letter": "C"
}

This allows you to interrupt running processes or send other control sequences when needed.

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.
