Mouse Control — Move, click, double-click, right-click, drag, scroll
Keyboard Input — Type text, press key combinations, hold keys
Cursor Position — Get current cursor coordinates
Clipboard — Read and write clipboard text
Application Management — List running apps, get frontmost app, open apps
Display Info — List connected displays with dimensions

Installation

Prerequisites

Bun >= 1.3.11
Windows 10/11

Install via npm

Terminal

npm install -g windows-computer-use-mcp

Install via npx (no install needed)

Terminal

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):

config.json

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

Or if installed globally:

config.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

鼠标控制 — 移动、单击、双击、右击、拖拽、滚轮滚动
键盘输入 — 输入文本、按键组合、长按按键
光标位置 — 获取当前光标坐标
剪贴板 — 读写剪贴板文本
应用管理 — 列出运行中的应用、获取前台应用、打开应用
显示器信息 — 列出已连接的显示器及分辨率

安装

环境要求

Bun >= 1.3.11
Windows 10/11

通过 npm 安装

Terminal

npm install -g windows-computer-use-mcp

通过 npx 运行（无需安装）

Terminal

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）：

config.json

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

或全局安装后：

config.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
