Install Computer Use in Claude Code, Cursor or VS Code
Runs npx -y computer-use-mcp on your machine. Read the scan report first; the gateway never runs local packages.

computer-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.

Computer Use: common questions
- Is Computer Use MCP server safe?
- Mostly: it is graded B (74/100). Read the Computer Use safety report
- How do I install Computer Use?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does Computer Use need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Computer Use maintained?
- The last commit was 56 days ago (2026-09-09). The latest release is v1.8.0.
- How does Computer Use compare with other MCP servers?
- safety score 74/100 (higher than 40% of 48,243 servers); tools 1 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
