[!TIP] Interested in Browser Use? Check out open-browser-use.

open-computer-use is an open-source Computer Use service wrapped as MCP. Any AI agent or MCP client can use it to run Computer Use on macOS, Linux, and Windows.

This project was inspired by OpenAI's Codex Computer Use. It showed that non-intrusive CUA can be built on top of Accessibility, so I decided to build an open-source version.

I started this repo with my harness template, a template for quickly spinning up AI-first projects. It has been one of our most useful workflows lately, especially for nearly 100% AI-generated projects. I also wrote a post about the methodology behind it.

Demos

Codex App and Codex CLI

open-computer-use used as Computer Use in Codex App and Codex CLI, matching the official experience.

Gemini CLI

https://github.com/user-attachments/assets/eacb3b15-f939-46c7-b3b3-6f876977a58d

Gemini CLI connects to open-computer-use through MCP and runs full Computer Use actions.

Linux

https://github.com/user-attachments/assets/e036b1c8-2200-4896-abd4-19225915cf66

open-computer-use running on Linux.

Quick Start

npm i -g open-computer-use

The npm package also exposes ocu as the short CLI alias.

[!IMPORTANT] The macOS runtime requires macOS 14.0 or later.

On macOS, run it once and grant Accessibility and Screen Recording. Windows and Linux do not need this step.

open-computer-use
# or
ocu

Before using it, install it into your agent:

# Install into Codex by writing to ~/.codex/config.toml
open-computer-use install-codex-mcp

Or add it to your own client manually:

{
  "mcpServers": {
    "open-computer-use": {
      "command": "open-computer-use",
      "args": ["mcp"]
    }
  }
}

Skill

Install the skill directly:

# Install for Codex
npx skills add iFurySt/open-codex-computer-use -g -a codex --skill open-computer-use -y
npx skills ls -g -a codex | rg 'open-computer-use'

Install for Claude Code:

npx skills add iFurySt/open-codex-computer-use -g -a claude-code --skill open-computer-use -y

Update an existing global install, including the Codex install created above:

npx skills update open-computer-use -g -y

You can also manually download and install the open-computer-use skill.

Besides the MCP JSON config above, you can also use the built-in commands:

# Install into Codex by writing to ~/.codex/config.toml
open-computer-use install-codex-mcp
ocu install-codex-mcp

# Install as a Codex plugin, mainly for Codex App
open-computer-use install-codex-plugin

# Install into Claude Code by writing to ~/.claude.json
open-computer-use install-claude-mcp

# Install into Gemini CLI for the current project by writing to ./.gemini/settings.json
open-computer-use install-gemini-mcp

# Install into Gemini CLI user config instead
open-computer-use install-gemini-mcp --scope user

# Install into opencode by writing to ~/.config/opencode/opencode.json (or the active config file)
open-computer-use install-opencode-mcp

# Install through DeepSeek Harness's generic MCP compatibility path:
# verifies the server, then writes a profile patch, turn-boundary hook, and skill
open-computer-use install-dsh-mcp
./scripts/install-dsh-mcp.sh --profile web --no-hook

# Call a single Computer Use tool and print the MCP-style JSON result
open-computer-use call list_apps
ocu call list_apps
open-computer-use call get_app_state --args '{"app":"TextEdit"}'

# Inspect code-first runtime availability
ocu capabilities
ocu capabilities --json

# Run one JavaScript evaluation, from an argument, stdin, or a file
ocu js 'var apps = await cua.listApps({ emit: false }); nodeRepl.write(apps)'
printf '%s' 'nodeRepl.write(6 * 7)' | ocu js -
ocu js --file ./automation.mjs

# Keep JavaScript and cua bindings for the current terminal session
ocu repl

# Run a sequence in one process so element_index state can be reused
# Sequence runs sleep 1s between successful operations by default
open-computer-use call --calls '[{"tool":"get_app_state","args":{"app":"TextEdit"}},{"tool":"press_key","args":{"app":"TextEdit","key":"Return"}}]'

# Show help
open-computer-use -h
ocu -h

ocu js closes its JavaScript Worker and native MCP child after one evaluation. ocu repl keeps them for the current terminal session until .exit, Ctrl-D, or termination; .reset clears its bindings. On macOS, the separate hidden Open Computer Use.app permission agent may remain resident so later commands reuse the same permission identity. ocu mcp continues to expose the native nine-tool compatibility surface.

The npm launcher itself currently requires Node.js 18 or newer. Its help always lists js / repl, while ocu capabilities --json reports whether Node, the REPL adapter/kernel, and the native runtime are available. Once started, it reuses the current Node executable instead of looking up another node on PATH.
