Windows GUI automation on a hidden second desktop, driven from Claude Code over MCP.

已验证STDIO仅桌面效率与工作流浏览器自动化

概览

AI 生成的概览

本地 Windows MCP 服务器，让助手在隐藏的第二个桌面上操作真实桌面应用，点击、输入和按键都会事后校验。

可以做什么
  • 列出并检查窗口：枚举可驱动的窗口、读取精简的 UI Automation 元素树、列出共享代理桌面上已打开的窗口
  • 在代理桌面上启动程序并报告其第一个带标题的窗口
  • 操作窗口：点击元素、输入文本、按下组合键、滚动，每步都对照窗口状态校验
  • 一次调用完成整个 GUI 任务，点击循环在服务器内部执行，只返回一段结果摘要
  • 查看历史运行：列出最近运行，或获取逐步日志及可视化回放链接
适用场景
适合让助手操作没有 API 的 Windows 应用，例如填写老旧工具或浏览桌面软件，同时用户仍可正常使用自己的屏幕、鼠标和键盘。适合使用 Windows 10 或 11、希望 GUI 自动化能明确报告成功或失败的用户。
运行要求
仅限 Windows 10 或 11，需安装商业版 agentfenster 应用，MCP 服务器随应用一起提供。本地 stdio 服务器，以 agentfenster-mcp 启动，需要应用自带的 Python 3.11 或更高版本。desktop_task 的点击循环需在应用中配置一个模型端点。未声明任何环境变量或请求头。
安装前请注意
该应用为商业闭源软件，所有方案先提供 3 天试用，之后需付费。删除、发送、支付或安装等高风险操作在 MCP 调用中默认被拒绝，因此部分任务会被报告为受阻而非完成。配置的模型端点是唯一的网络流量，提示内容和从界面提取的元素数据会发送到该端点。操作会改变真实应用状态。

安装

在 SourceWeft 中

  1. 打开 控制台中的 agentfenster，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

agentfenster MCP server

The agentfenster MCP server lets Claude Code and other MCP clients drive real Windows applications on a hidden second desktop inside your own session, with the same logins, cookies and VPN, while you keep your screen, mouse and keyboard. It is a local stdio server with 11 tools, from a one call task loop down to single verified clicks.

Every action is verified against the window state afterwards. A click that lands nowhere is reported as a failure, never as a silent success.

Full documentation: https://agentfenster.com/mcp

The MCP server ships with the agentfenster app, a commercial closed-source Windows product. This repository is its public documentation and issue tracker. It contains no product source code.

Install

  1. Install agentfenster on Windows 10 or 11 from https://agentfenster.com. The MCP server is part of the app. Every plan starts with a 3-day trial, no card and no account required.
  2. Register the server with Claude Code:
bash
claude mcp add agentfenster -- agentfenster-mcp

Any MCP client that can launch a local stdio server works the same way. Then just ask:

> open the character map on the agent desktop and turn on the advanced view

The 11 tools

ToolWhat it does
list_windowsLists the windows this machine can drive, with title, class, minimized state and whether a picture can be captured. The starting point when you do not know the exact window title.
desktop_taskRuns a full GUI task in one window and returns a single paragraph: what happened, whether it worked, and if not, which step failed and why. The click loop runs inside the server, so its retries never enter your context.
inspect_windowReturns the capped, filtered element tree of one window as a compact list, for planning clicks yourself. Capped at 200 elements and never walked from the desktop root.
replayLists recent runs, or returns one run's step-by-step log: every plan, every action, whether it changed anything, and a link to the visual replay in the app.
open_appLaunches a program on the shared agent desktop and reports its first titled window. The agent desktop starts empty, so this is how anything gets onto it.
read_desktopReads the compact element tree of a window on the agent desktop, one line per interactive element, no screenshot. Plan your clicks from this.
clickClicks one element, chosen by id or name from read_desktop, then verifies against the desktop state and states explicitly whether anything changed.
type_textTypes text into one element on the agent desktop, then verifies whether anything changed.
press_keyPresses a key or key combination such as ctrl+s, enter, tab or alt+f4, optionally focusing an element first, with verification afterwards.
scrollScrolls a window or a specific pane and reports whether the content actually moved. A list that is already at the bottom reports no effect.
agent_windowsLists the windows currently open on the shared agent desktop, frontmost first, so you can pick one by a title substring.

How it works

  • The agent works on a second Win32 desktop inside your session. It never takes your foreground, mouse or keyboard, and you can watch it live in the app.
  • Tools read the UI Automation element tree instead of screenshots: one line per interactive element, capped at 200 elements per window.
  • The click loop of desktop_task runs inside the server on a model endpoint you configure, so its retries and intermediate steps never enter your context.
  • Risky actions such as delete, send, pay or install are denied by default on MCP calls and reported, instead of blocking on a confirmation nobody can answer.
  • agentfenster sends no telemetry. The only network traffic is the model endpoint you configure for the click loop.

Requirements

PlatformWindows 10 or 11
Transportstdio, local
RuntimePython 3.11 or newer, installed with the app
Prerequisitethe agentfenster app (commercial, 3-day trial)

Issues

Use the issue tracker of this repository for bug reports and questions about the MCP server: tool behaviour, install problems, MCP client compatibility. For anything about the app itself, Discord and [email protected] are faster.
