Computer Use — Claude Code MCP server: what it does, how to install
An MCP server that gives your model desktop control through screenshots and keyboard actions. It automates local GUI tasks directly from your prompt.
claude mcp add computer-use-mcp -- npx -y computer-use-mcpWhat Computer Use does
The server replicates the mechanics of Anthropic's computer use tool on your local machine. It connects to the desktop environment through nut.js. The model captures screen state and dispatches simulated inputs.
Accuracy drops at high screen resolutions. Lowering display settings to 720p or zooming in on target windows prevents misplaced clicks. For browsing, pairing this with the Rango extension replaces coordinate guessing with direct keyboard shortcuts.
Full mouse and keyboard access opens real security risks under prompt injections. Run this inside an isolated operating system profile to keep personal files safe.
What it helps with
- automate repetitive desktop application workflows
- navigate web pages using keyboard shortcut hints
- change system settings and desktop backgrounds
- test desktop software interfaces with simulated user input
Example prompts for the agent
- Open the display settings window and change my desktop wallpaper.
- Launch the browser, find the documentation link using keyboard hints, and open it.
