**ComputerMate** is a powerful Model Context Protocol (MCP) server that grants AI models the ability to interact with your computer just like a human would. From taking screenshots to clicking buttons and typing text, ComputerMate exposes your local machine (or a sandboxed Docker container) as a set of tools for LLMs.

## ✨ Features & Highlights

- 🖥️ **Cross-Platform**: Unified support for **Linux**, **macOS**, and **Windows** via a single `native` mode.
- 🐳 **Docker-First**: Run in a fully isolated Linux desktop environment with VNC access and state persistence.
- 🖱️ **Virtual Cursor**: Enable a visual mouse cursor in Playwright by setting `VIRTUAL_CURSOR=true`.
- 🌐 **Web Automation**: Integrated **Playwright** support for high-performance, browser-only computer use.
- 📐 **Smart Scaling**: Automatically scale screenshots and coordinates to fit LLM context limits via `MAX_SCALING_DIMENSION`.

## 🛠️ Available Tools

ComputerMate exposes the following tools to the LLM:

| Tool                | AI-Friendly Description                                                |
| :------------------ | :--------------------------------------------------------------------- |
| `screenshot`        | Take a full screenshot of the current screen or browser viewport.      |
| `screenshot_region` | Capture a specific rectangular area by providing two diagonal points.  |
| `click`             | Move pointer and click (left, middle, right supported).                |
| `double_click`      | Rapidly click twice at the given coordinates.                          |
| `scroll`            | Scroll the window content at (x, y) by given amount.                   |
| `type`              | Send keyboard text input to the active window.                         |
| `keypress`          | Send key combinations (e.g. `["ctrl", "c"]`, `["alt", "tab"]`).        |
| `move`              | Move the mouse pointer without clicking.                               |
| `drag`              | Drag the mouse from start point along a path of coordinates.           |
| `wait`              | Pause execution for a set number of milliseconds.                      |
| `get_dimensions`    | Retrieve the screen or viewport width and height.                      |
| `get_environment`   | Returns the current platform (`linux`, `macos`, `windows`, `browser`). |
| `goto`              | **(Playwright only)** Navigate to a specific URL.                      |
| `back`              | **(Playwright only)** Go back in history.                              |
| `forward`           | **(Playwright only)** Go forward in history.                           |
| `get_current_url`   | **(Playwright only)** Retrieve the current active page URL.            |

## 🚀 Quick Start

### 📦 Using npx (Local)

Run the server directly without installing:

```bash
# For local OS interaction (macOS, Windows, Linux)
npx @one710/computermate native

# For Playwright (Browser only)
npx @one710/computermate playwright
```

### 🐳 Using Docker (Safe & Persistent)

The recommended way to use ComputerMate is via Docker. This provides a sandboxed environment and VNC access.

```bash
# Clone the repository
git clone https://github.com/one710/computermate.git
cd computermate

# Start the server with persistence
docker-compose up --build
```

- **MCP Endpoint**: `http://localhost:3000`
- **VNC View**: `localhost:5900` (Password: `one710`)

## 🛠️ Prerequisites & Installation

### 🐧 Linux (Ubuntu / Debian Desktop)

```bash
sudo apt-get update
sudo apt-get install -y libxtst-dev libpng-dev xvfb xdotool
```

### 🍎 macOS

Ensure you have granted **Accessibility** permissions to your terminal or IDE (e.g., Cursor, VS Code, iTerm2) in _System Settings > Privacy & Security > Accessibility_.

### 🪟 Windows

No external binaries are required!

## ⚙️ Configuration

### Environment Variables

| Variable                | Purpose                                                                             | Default  |
| :---------------------- | :---------------------------------------------------------------------------------- | :------- |
| `COMPUTER_TYPE`         | **(Docker / HTTP)** Sets the computer backend: `native` or `playwright`.            | `native` |
| `MAX_SCALING_DIMENSION` | Caps the max width or height of screenshots (e.g., `1024x768`). Scales coordinates. | None     |
| `VIRTUAL_CURSOR`        | **(Playwright)** Shows a visual red dot where the "mouse" is.                       | `false`  |
| `HEADLESS`              | **(Playwright)** Runs the browser in headless mode.                                 | `false`  |

## 🏗️ Local Development

To run from source:

```bash
# 1. Install dependencies
npm install

# 2. Build the project
npm run build

# 3. Run the server
node dist/index.js native
```

## ⚠️ Important Warnings

> [!CAUTION]
> **This tool grants significant control over your system.**
> An LLM with access to ComputerMate can read your files, access your browser, and execute commands as the current user.
>
> - **Use with Caution**: Do not run this on a machine with sensitive data or production access.
> - **Sandbox Recommended**: Use the [Docker](#using-docker-safe--persistent) environment for maximum safety.
> - **Monitor closely**: Always keep an eye on what the AI is doing.

## 🛠️ MCP Configuration

Add this to your `claude_desktop_config.json` (or equivalent MCP client config):

```json
{
  "mcpServers": {
    "computermate": {
      "command": "npx",
      "args": ["-y", "@one710/computermate", "native"],
      "env": {
        "MAX_SCALING_DIMENSION": "1024x768"
      }
    }
  }
}
```

### 🌉 Stdio-to-Docker Bridge (mcp-remote)

If your MCP client (like Cursor or older versions of Claude Desktop) only supports `stdio` transports, you can bridge it to the ComputerMate Docker container:

```json
{
  "mcpServers": {
    "computermate": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "http://localhost:3000/mcp",
        "--transport",
        "http-only"
      ]
    }
  }
}
```

This command starts a local `stdio` server that transparently forwards all requests to the ComputerMate container running at `http://localhost:3000`.
