## Installation

### Prerequisites

- [Bun](https://bun.sh/) >= 1.3.11
- Windows 10/11

### Install via npm

```bash
npm install -g windows-computer-use-mcp
```

### Install via npx (no install needed)

```bash
npx windows-computer-use-mcp
```

### Build from source

```bash
git clone https://github.com/hiphopanda/windows-computer-use-mcp.git
cd windows-computer-use-mcp
bun install
bun run build
```

## Configuration

Add to your MCP client settings (e.g. Claude Desktop):

```json
{
  "mcpServers": {
    "computer-use": {
      "type": "stdio",
      "command": "npx",
      "args": ["windows-computer-use-mcp"]
    }
  }
}
```

Or if installed globally:

```json
{
  "mcpServers": {
    "computer-use": {
      "type": "stdio",
      "command": "windows-computer-use-mcp"
    }
  }
}
```

## Development

```bash
bun install          # Install dependencies
bun run dev          # Run in development mode
bun run build        # Build to dist/
bun run start        # Run built version
```

## Architecture

- **Runtime**: Bun + TypeScript
- **Transport**: stdio (MCP protocol)
- **Platform Layer**: All desktop operations go through PowerShell scripts executed via `Bun.spawn`
- **Low-level Input**: Uses Win32 P/Invoke (`user32.dll`) loaded at runtime — no precompiled native modules needed

## 安装

### 环境要求

- [Bun](https://bun.sh/) >= 1.3.11
- Windows 10/11

### 通过 npm 安装

```bash
npm install -g windows-computer-use-mcp
```

### 通过 npx 运行（无需安装）

```bash
npx windows-computer-use-mcp
```

### 从源码构建

```bash
git clone https://github.com/hiphopanda/windows-computer-use-mcp.git
cd windows-computer-use-mcp
bun install
bun run build
```

## 配置

在 MCP 客户端配置中添加（如 Claude Desktop）：

```json
{
  "mcpServers": {
    "computer-use": {
      "type": "stdio",
      "command": "npx",
      "args": ["windows-computer-use-mcp"]
    }
  }
}
```

或全局安装后：

```json
{
  "mcpServers": {
    "computer-use": {
      "type": "stdio",
      "command": "windows-computer-use-mcp"
    }
  }
}
```

## 开发

```bash
bun install          # 安装依赖
bun run dev          # 开发模式运行
bun run build        # 构建到 dist/
bun run start        # 运行构建产物
```

## 架构

- **运行时**：Bun + TypeScript
- **传输层**：stdio（MCP 协议）
- **平台层**：所有桌面操作通过 `Bun.spawn` 执行 PowerShell 脚本
- **底层输入**：通过 Win32 P/Invoke（`user32.dll`）在运行时加载 — 无需预编译原生模块
