Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@computer-use-winFind the login button and click it, then type 'admin' in the username field."
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.

给 DeepSeek Harness 装上 Windows 电脑操控能力——MCP stdio 服务器 + PowerShell/UIA 桌面引擎,22 个工具让 agent 能看(UIA 无障碍树、窗口裁剪截图、OCR 词框)也能做(鼠标、键盘、UIA 语义动作、窗口管理)真实的 Windows 桌面应用。
通过 DSH 内置的 @deepseek-ai/dsh-mcp-client 桥接,不改 DSH 本体,零运行时依赖。

特性
文本优先的观察——UIA 无障碍树三视图(
control/content/raw);按 name/automationId/类名/值找控件,不靠猜像素。元素 id 用 UIA RuntimeId(UI 刷新后仍稳定,过期报stale而非点错地方)。三级截图链——
PrintWindow(非前台窗口也能抓)→ WGC(Windows.Graphics.Capture,DirectComposition/被遮挡窗口)→ 屏幕区域兜底(带occludedPossible标记)。窗口裁剪 + 降采样 +imageScale/origin坐标映射,PNG 30 分钟自动清理。三条输入路径,诚实上报——语义(UIA pattern,不碰鼠标)/ 前台(
SetCursorPos+ SendInput + 剪贴板 /KEYEVENTF_UNICODE)/ 后台(PostMessage 直进窗口消息队列,不抢前台;投递未验证,如实verified:false——Chromium/Electron/WinUI 会静默丢合成消息,工具会明说)。UIA 盲区 OCR 回退——
Windows.Media.Ocr(csc 编译的 C# WinRT 助手);返回文字 + 逐词屏幕坐标词框,query命中后自动回查匹配词下的控件(ControlFromPoint)。内置安全机制
坐标 homing——观察后窗口被移动,点击自动补偿并回报
homed:{dx,dy}急停 failsafe——物理鼠标停屏幕角落 500ms,所有输入被拒(
EMERGENCY STOP),只有人把鼠标移开才恢复identity guard——按
windowTitle操作时窗口 HWND/PID 变了就拒绝(identity_changed)前台校验——输入 fail-closed:目标窗口不是真前台就直接报错,绝不打进别的窗口
Win 键黑名单——
Win+R/X/L/S类组合按设计拦截
持久化后端——一个常驻 PowerShell 进程 + JSON 行协议,热态延迟 6–100ms(首次 ~500ms 冷启动);C# P/Invoke 助手按 hash 编译成缓存 DLL,重启免重编。

安装
# 从 GitHub(--profile 指定装进哪个 profile)
dsh plugin --profile web add github:Yu-tao-Li/dsh-computer-use-win
# 或在 DSH 设置的插件市场(dshmarket)搜索 dsh-computer-use-win重启 dsh web,工具以 mcp__wincu__windows_computer_use_* 出现。
bundle 在安装时自解析路径(
cordis.patch.yml用!!js相对包目录),任何 profile /$DSH_HOME都能装,无硬编码路径。同一 profile 只保留一个serverName: wincu行。

所有工具都支持可选窗口定位(windowTitle 子串 / processId / nativeWindowHandle)+ activate: true;不指定 = 当前前台窗口。
架构
DSH agent
│ 模型看到 mcp__wincu__windows_computer_use_* 工具
▼
@deepseek-ai/dsh-mcp-client ← DSH 内置桥接(官方 MCP SDK StdioClientTransport)
│ JSON-RPC 2.0 over stdio(按行分帧)
▼
mcp/server.mjs ← 本仓库:MCP 服务器(Node ≥22,零依赖)
│ 保活一个持久化后端;JSON 行协议
▼
scripts/windows-uia.ps1 ← 本仓库:桌面引擎(PowerShell 5.1 兼容)
├─ UI Automation 程序集 → 无障碍树
├─ user32 P/Invoke(C# 缓存 DLL)→ 鼠标/键盘/窗口操作
├─ Windows.Media.Ocr(C# WinRT)→ OCR
└─ Windows.Graphics.Capture → WGC 窗口捕获安全与限制
动作是真实的——敏感操作前让 agent 先
snapshot;重要窗口用windowTitle明确限定。WinUI / Chromium / Electron 会丢弃 PostMessage 合成输入(
verified:false是诚实上报,不是成功)。这类目标走前台/剪贴板路径。提权窗口(UAC/管理员程序)UIA 与合成输入都被 Windows 拦截,读不到也点不了。
坐标以物理像素为准(显式 Per-Monitor V2 DPI)。
OCR 对 CJK 按字符给词框(引擎特性),点选足够用。
仅支持 Windows。
