munim-computer-use
Open-source Computer Use MCP server for any coding agent — macOS, Windows, Linux. Accessibility-first, background input, agent pointer, zoom, your signed-in Chrome.
Install / Use
claude mcp add munimtechnologies -- npx -y github:munimtechnologies/munim-computer-useIf the server publishes to npm under a different name, use that package instead — check the repo README.

Our assessment of munim-computer-use
munim-computer-use scores 84/100 on our quality scale, 1124th of 1,753 Automation skills we index.
Its MCP Server is 29 KB long, well organised into 26 sections with 7 code examples: a thorough specification that gives an agent plenty to work with.
It has 10 GitHub stars, so there is little community track record yet; judge it on its content.
Maintenance, license and trust
- The repository was last updated 5 days ago, so munim-computer-use is actively maintained.
- Our last check on 2026-09-25 found the source still online.
- It is released under the Apache-2.0 license, a permissive license that allows use, modification and commercial use with attribution.
- Its trust signals score 97/100, with no cautions. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Skill content
View source on GitHubIntroduction
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
- 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. - Put it somewhere on your
PATH(/usr/local/bin/munim-computer-use, or%LOCALAPPDATA%\Programs\munim-computer-use\munim-computer-use.exe). - macOS only: run
munim-computer-use request-permissionsonce to be prompted for Accessibility and Screen Recording. - 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 | Munim Computer Use | Codex Computer Use | Anthropic reference demo | Windows-MCP | MacOS-MCP | open-computer-use | computer-use-mcp (zavora) | Notes |
| ------------------------------------------- | ---------------------- | ------------------ | ------------------------ | ----------- | --------- | ----------------- | ------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| macOS | ✅ | ✅ | ❌ | ❌ | ✅ | ✅ | ✅ | The Anthropic demo drives a Linux desktop inside Docker, not your machine. |
| Windows | ✅ | ✅ | ❌ | ✅ | ❌ | ✅ | ✅ | Windows-MCP is Windows only; MacOS-MCP is macOS only. |
| Linux | ✅ | ❌ | ✅ (sandbox) | ❌ | ❌ | ✅ | ✅ | Munim Computer Use uses AT-SPI + X11; native Wayland apps get element actions but not coordinate clicks. |
| Accessibility tree with element ids | ✅ | ❌ | ❌ | ✅ | ✅ | ✅ | ✅ | Codex and the Anthropic demo are screenshot-driven. Ids let the agent press the button instead of a pixel. |
| Background input (your mouse never moves) | ✅ | ✅ | 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 does this too, with a second cursor of its own. Every other server in this table drives the real cursor. |
| Agent pointer overlay | ✅ | ✅ | ❌ | ⚠️ | ❌ | ❌ | ❌ | Windows-MCP flashes a border around captures; Codex draws its own cursor on your screen. |
| Zoom into a region at full resolution | ✅ | ❌ | ✅ | ❌ | ❌ | ❌ | ❌ | Anthropic's toolset has zoom; here it is a tool on every platform. |
| Screenshots carry screen-coordinate mapping | ✅ | n/a | n/a | ❌ | ❌ | ❌ | ❌ | Origin and pixels-per-point in every capture, so clicks from Retina or downscaled images land. |
| Hover, wait, label query | ✅ | ⚠️ | ⚠️ | ✅ | ⚠️ | ❌ | ⚠️ | Windows-MCP has Wait/WaitFor; MacOS-MCP has Wait; Anthropic has wait/mouse_move. |
| Your signed-in Chrome, own tab group or yours | ✅ | ⚠️ | ❌ | ⚠️ | ❌ | ❌ | ❌ | Codex uses its in-app browser; Windows-MCP reads the DOM of open browsers. Munim Computer Us
