open-computer-use

Cross-platform npm distribution for the open-source Open Computer Use MCP server.

This package bundles native runtimes for these supported platforms and lets the Node launcher choose the current process.platform / process.arch pair:

• darwin-arm64
• darwin-x64
• linux-arm64
• linux-x64
• win32-arm64
• win32-x64

Global command aliases:

• open-computer-use
• ocu
• open-computer-use-mcp
• open-codex-computer-use-mcp

Install

npm install -g open-computer-use

The root launcher resolves the current process.platform / process.arch pair and runs the matching bundled native runtime.

MCP config

If your MCP client accepts a stdio-style mcpServers JSON config, this is the default setup:

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

Notes

• Version: 1.1.2
• Supported npm platforms: darwin-arm64, darwin-x64, linux-arm64, linux-x64, win32-arm64, win32-x64
• ocu js creates a one-shot JavaScript/native session; ocu repl keeps one session for the current terminal and preserves bindings between evaluations.
• Both code-first commands use the Node executable that started the npm launcher. The npm launcher itself still requires Node.js 18 or newer to be available when the command starts.
• ocu mcp intentionally continues to expose the native 9-tool compatibility surface; the Codex plugin adapter exposes js / js_reset separately.
• macOS still requires Accessibility and Screen Recording permissions.
• Linux requires a signed-in desktop session with AT-SPI2 / D-Bus accessibility available for real app control.
• Windows requires a signed-in desktop session for UI Automation access.
