Introduction

Computer Use is an open-source MCP server — a computer-use agent (CUA) backend — that lets any coding agent use your computer the way a person does. It reads the screen through accessibility trees, clicks and types in the background so your mouse stays yours, shows an agent pointer where it is working, zooms in on small text, and drives tabs in your signed-in Chrome — on macOS, Windows and Linux.

Works with Claude Code, Codex, Cursor and MT Code, or any other MCP client, with any model — no vision model is required for interaction.

Built by Munim Technologies as the Computer Use engine of MT Code, and published here on its own.

Quick start

1. Download the latest binary for your platform from Releases (computer-use-macos-universal.zip, computer-use-windows-x64.zip) or build from source.
2. Put it somewhere on your PATH (/usr/local/bin/computer-use, or %LOCALAPPDATA%\Programs\computer-use\computer-use.exe).
3. macOS only: run computer-use request-permissions once to be prompted for Accessibility and Screen Recording.
4. Register it with your agent:

# Claude Code — fastest: the npm launcher fetches the signed binary on first run
claude mcp add computer-use -- npx -y munim-computer-use
# or point at a downloaded binary
claude mcp add computer-use -- /usr/local/bin/computer-use

# Codex — ~/.codex/config.toml
[mcp_servers.computer-use]
command = "npx"
args = ["-y", "munim-computer-use"]

// Cursor — .cursor/mcp.json
{ "mcpServers": { "computer-use": { "command": "npx", "args": ["-y", "munim-computer-use"] } } }

Then ask: "Open Safari, find the cheapest flight to Denver on Tuesday and put it in a note." The agent reads the UI with get_app_state, acts by element id, and verifies with screenshot.
