About Computer Use
Computer Use is a local MCP server that lets Claude control a computer through screenshots, mouse input, and keyboard automation. It is for users who want to automate desktop tasks, with behavior modeled on Anthropic’s computer-use tool and a preference for keyboard shortcuts.
Key features
- 01Screenshot-based computer interaction
- 02Mouse and keyboard automation
- 03Keyboard-shortcut guidance
- 04Local setup for MCP clients
Use cases
- 01Automating desktop tasks with Claude
- 02Changing desktop settings through computer control
- 03Navigating websites with keyboard input
MCP support
It exposes a computer-use tool to MCP clients, allowing Claude to interact with the computer using screenshots, mouse, and keyboard controls.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From the project READMEcomputer-use-mcp
💻 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.
Here's Claude Haiku 4.5 changing my desktop background (4x speed):

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.
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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
