Windows Command Line MCP Server MCP server

The Windows Command Line MCP Server provides a secure bridge between AI models and Windows system operations, allowing controlled execution of commands, project creation, and system information retrieval while maintaining strict security protocols.

Installation

Prerequisites

• Node.js 16 or later
• npm or yarn
• Windows operating system

Installing via Smithery

You can install Windows Command Line MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @alxspiker/Windows-Command-Line-MCP-Server --client claude

Manual Setup

git clone https://github.com/alxspiker/Windows-Command-Line-MCP-Server.git

npm install
npm run build

Using with Claude for Desktop

To use this server with Claude for Desktop:

1. Build the server using the setup instructions above
2. Add it to your claude_desktop_config.json:

{
  "mcpServers": {
    "windows-cmd": {
      "command": "node",
      "args": ["/path/to/dist/index.js"]
    }
  }
}

Replace /path/to/dist/index.js with the absolute path to the built index.js file in the dist directory.

3. Restart Claude for Desktop
4. You can now use the tools by asking Claude to perform Windows system operations

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "windows-cmd" '{"command":"node","args":["/path/to/dist/index.js"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "windows-cmd": {
            "command": "node",
            "args": [
                "/path/to/dist/index.js"
            ]
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "windows-cmd": {
            "command": "node",
            "args": [
                "/path/to/dist/index.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
