Overview
computer-use-mcp MCP Server
An MCP server that gives Claude local computer control, mouse, keyboard, and screen access via nut.js, implementing the same computer use tool Anthropic documents officially, but easy to set up for local use across Claude Code, Claude Desktop, Cursor, Cline, and VS Code. Use it, with close supervision, when Claude needs to directly operate a desktop or browser UI. Treat it like giving a hyperactive toddler full computer access, and consider a sandboxed user account given current models' mistakes and prompt-injection vulnerability.
What it does
An MCP server that gives Claude direct control of a local computer, the mouse, keyboard, and screen, implementing a near-identical version of Anthropic's official computer use tool, but packaged for easy local setup instead of the sandboxed environment computer use normally runs in. It talks to the computer through nut.js, a cross-platform desktop automation library, so Claude can see the screen and act on it the same way a person would with a mouse and keyboard.
When to use - and when NOT to
Use it when a task genuinely needs hands-on control of a desktop UI that no API or CLI can reach - changing a setting buried in an app's GUI, navigating a website, or driving a workflow across multiple applications. The project's own warning is explicit and should be taken seriously: models currently make frequent mistakes and are vulnerable to prompt injection, and because this server gives complete computer control, that can cause real damage. Treat it like handing a hyperactive toddler the keyboard - supervise closely, and consider running it only in a sandboxed user account rather than a primary one with access to sensitive data or accounts.
Capabilities
The server exposes a computer-use tool closely mirroring Anthropic's official specification, with extra nudging toward keyboard shortcuts over mouse clicks where possible, since coordinate-based clicking is less reliable than keyboard navigation. Reliability tips from the maintainer: use a capable model, the latest Claude models are recommended, run at a small, common resolution such as 720p rather than a high-DPI display, and install the Rango browser extension, which adds keyboard-driven navigation hints to web pages so Claude can jump to elements by typing a hint instead of clicking coordinates.
How to install
Follow the generated configuration from install-mcp, which produces the right config for Claude Code, Claude Desktop, Cursor, Cline, VS Code, and other MCP clients automatically from a single link, so no manual config file editing is required.
Who it's for
Users experimenting with agentic desktop control who want Claude to directly operate their screen for tasks with no API path, and who are willing to supervise closely and run it in a sandboxed account given the current risk of mistakes and prompt injection.

💻 A 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.

Installation
Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).
Tips
This should just work out of the box.
However, to get best results:
- Use a model good at computer use - I recommend the latest Claude models.
- Use a small, common resolution - 720p works particularly well. On macOS, you can use displayoverride-mac to do this. If you can't use a different resolution, try zooming in to active windows.
- Install and enable the Rango browser extension. This enables keyboard navigation for websites, which is far more reliable than Claude trying to click coordinates. You can bump up the font size setting in Rango to make the hints more visible.
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.
