What is Computer Use Mcp

computer-use-mcp is a model context protocol server designed for Claude to control your computer. It simplifies the process of computer interaction, similar to the official computer use guide from Anthropic.

Use cases

Use cases include automating repetitive tasks, assisting users with disabilities in navigating their computers, and testing web applications by simulating user interactions.

How to use

To use computer-use-mcp, add the specified configuration to the ‘mcpServers’ section of your ‘claude_desktop_config.json’. Ensure you have the Rango browser extension installed for better navigation.

Key features

Key features include easy local setup, keyboard shortcut preference for navigation, and compatibility with high-resolution displays. It utilizes nut.js for communication with your computer.

Where to use

computer-use-mcp can be used in various fields where automated computer control is beneficial, such as software testing, accessibility tools, and personal productivity enhancements.

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"
      ]
    }
  }
}
