Which integrations are available for this server?

Provides native macOS computer control, including mouse and keyboard simulation, screenshot capture, display management, and application control.

How do I use macos-computer-use-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@macos-computer-use-mcp Open the Notes app and type 'Buy milk and eggs'" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

macos-computer-use-mcp

A standalone MCP server providing native macOS computer control — mouse, keyboard, screenshots, and app management — for any MCP-compatible agent.

Demo

Screenshot & Click in action — The MCP server grants app access, captures a 2560×1664 native screenshot, clicks on-screen elements, and opens URLs — all orchestrated through standard MCP tool calls from a coding agent.

Compatibility

Works with any client that supports the Model Context Protocol, including:

Claude Code (claude mcp add)
OpenAI Codex (~/.codex/config.toml)
Cursor (~/.cursor/mcp.json)
Any other MCP-compatible agent or IDE

How It Works

The server exposes macOS system control as MCP tools. Under the hood it uses macOS native modules for low-level input simulation and system APIs:

@ant/computer-use-input — Low-level mouse and keyboard event injection
@ant/computer-use-swift — macOS native APIs for display management, app control, and screenshots

The MCP server process communicates over stdio, so any agent can spawn it as a subprocess and call its tools via the standard JSON-RPC protocol.

Installation

curl -fsSL https://raw.githubusercontent.com/Zooeyii/macos-computer-use-mcp/main/install.sh | bash

Or manually:

git clone https://github.com/Zooeyii/macos-computer-use-mcp.git ~/.local/share/macos-computer-use-mcp
cd ~/.local/share/macos-computer-use-mcp
npm install
npm run build

Configuration

Claude Code

claude mcp add -s user computer-use-standalone node $HOME/.local/share/macos-computer-use-mcp/dist/cli.js

Or add to ~/.claude/mcp.json:

{
  "computer-use-standalone": {
    "type": "stdio",
    "command": "node",
    "args": ["$HOME/.local/share/macos-computer-use-mcp/dist/cli.js"]
  }
}

OpenAI Codex

Add to ~/.codex/config.toml:

[mcp_servers.computer-use-standalone]
command = "node"
args = ["$HOME/.local/share/macos-computer-use-mcp/dist/cli.js"]

Or via CLI:

codex mcp add computer-use-standalone -- node $HOME/.local/share/macos-computer-use-mcp/dist/cli.js

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "computer-use-standalone": {
      "command": "node",
      "args": ["$HOME/.local/share/macos-computer-use-mcp/dist/cli.js"]
    }
  }
}
