MCP.Pizza Chef: domdomegg

computer-use-mcp is an MCP server designed to let Claude control your computer locally. It integrates with the Rango browser extension for reliable keyboard navigation on websites, improving interaction accuracy. While powerful, it carries risks due to models' frequent mistakes and vulnerability to prompt injections, so it should be used cautiously. This server simplifies local computer automation by exposing control capabilities to Claude via MCP.

README

computer-use-mcp

💻 An model context protocol server for Claude to control your computer. This is very similar to computer use, but easy to set up and use locally.

To get best results:

  • Install and enable the Rango browser extension. This enables keyboard navigation for websites, which is far more reliable than Claude trying to click coordinates.
  • On high resolution displays, consider zooming in to active windows. You can also bump up the font size setting in Rango to make the text more visible.

Warning

At time of writing, models make frequent mistakes and are vulnerable to prompt injections. As this MCP server gives the model complete control of your computer, this could do a lot of damage. You should therefore treat this like giving a hyperactive toddler access to your computer - you probably want to supervise it closely, and consider only doing this in a sandboxed user account.

How it works

We implement a near identical computer use tool to Anthropic's official computer use guide, with some more nudging to prefer keyboard shortcuts.

This talks to your computer using nut.js.

Usage

To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your claude_desktop_config.json:

{
  "mcpServers": {
    "computer-use": {
      "command": "npx",
      "args": [
        "-y",
        "computer-use-mcp"
      ]
    }
  }
}

computer-use-mcp FAQ

How do I set up computer-use-mcp for best results?
Install the Rango browser extension to enable reliable keyboard navigation and consider zooming in on active windows or increasing font size for better visibility.
What are the security risks of using computer-use-mcp?
Since the model gains full control of your computer, it is vulnerable to prompt injections and mistakes, so treat it cautiously like giving a hyperactive toddler access to your system.
Can computer-use-mcp be used with models other than Claude?
While designed for Claude, the MCP protocol is provider-agnostic, so it may work with other models supporting MCP, such as OpenAI's GPT-4, Anthropic's Claude, and Google Gemini, with appropriate adaptation.
Is computer-use-mcp suitable for high-resolution displays?
Yes, but it is recommended to zoom in on active windows or increase font size in the Rango extension for better text visibility and interaction accuracy.
Does computer-use-mcp require internet access to function?
No, it is designed to be used locally, enabling offline control of your computer through Claude and MCP.
How does computer-use-mcp improve web navigation reliability?
By integrating with the Rango browser extension, it uses keyboard navigation instead of unreliable coordinate clicking, enhancing interaction precision.
