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](https://munimtech.com/mtcode), or any other MCP client, with any model — no vision model is required for interaction.

Built by [Munim Technologies](https://munimtech.com/munim-computer-use) 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 (munim-computer-use-macos-universal.zip, munim-computer-use-windows-x64.zip) or build from source.
2. Put it somewhere on your PATH (/usr/local/bin/munim-computer-use, or %LOCALAPPDATA%\Programs\munim-computer-use\munim-computer-use.exe).
3. macOS only: run munim-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.

Add --scope user to register it for every project instead of just this one.

claude mcp add munim-computer-use -- npx -y munim-computer-use

or point at a downloaded binary

claude mcp add munim-computer-use -- /usr/local/bin/munim-computer-use

# Codex — writes the entry below into ~/.codex/config.toml for you (needs a Codex CLI

with codex mcp; check with codex mcp --help)

codex mcp add munim-computer-use -- npx -y munim-computer-use

# Codex — ~/.codex/config.toml, if you would rather edit it yourself

[mcp_servers.munim-computer-use] command = "npx" args = ["-y", "munim-computer-use"]

# Cursor — no MCP subcommand in its CLI, so write the config. ~/.cursor/mcp.json applies

to every project; .cursor/mcp.json in a repo applies to that one.

mkdir -p ~/.cursor && [ -s ~/.cursor/mcp.json ] || echo '{}' > ~/.cursor/mcp.json jq '.mcpServers["munim-computer-use"] = {"command":"npx","args":["-y","munim-computer-use"]}' \ ~/.cursor/mcp.json > ~/.cursor/mcp.json.tmp && mv ~/.cursor/mcp.json.tmp ~/.cursor/mcp.json

// Cursor — the entry that produces, in .cursor/mcp.json

{ "mcpServers": { "munim-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.

Capability matrix

Munim Computer Use is the highlighted first column; the others are the computer-use servers people reach for. each cell comes from that project's own README or docs in September and October 2026 (sources under Credits and license). ✅ present · ❌ absent or not documented · ⚠️ partial.

| Background input (your mouse never moves) | ✅ | ✅ | ⚠️ | n/a | n/a | ❌ | ❌ | ❌ | ❌ | Munim Computer Use addresses events to the target window: always on macOS (SkyLight and per-process events), for UI Automation patterns and classic Win32 controls on Windows; other Windows UI and all Linux pointer input (XTEST) still move the real pointer. Codex works in the background on macOS w
