com.agentfenster由 agentfenster.com 發布v0.1.0更新於 Oct 27, 2026

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

已驗證STDIO僅桌面效率與工作流瀏覽器自動化

概覽

AI 產生的概覽

本機 Windows MCP 伺服器，讓助理在隱藏的第二個桌面上操作真實桌面應用程式，點擊、輸入與按鍵都會事後驗證。

可以做什麼
  • 列出並檢視視窗：列舉可驅動的視窗、讀取精簡的 UI Automation 元素樹、列出共用代理桌面上已開啟的視窗
  • 在代理桌面上啟動程式並回報其第一個有標題的視窗
  • 操作視窗：點擊元素、輸入文字、按下組合鍵、捲動，每步都對照視窗狀態驗證
  • 一次呼叫完成整個 GUI 任務，點擊迴圈在伺服器內部執行，只回傳一段結果摘要
  • 檢視歷史執行：列出最近執行，或取得逐步日誌及視覺化重播連結
適用情境
適合讓助理操作沒有 API 的 Windows 應用程式，例如填寫老舊工具或瀏覽桌面軟體，同時使用者仍可正常使用自己的螢幕、滑鼠與鍵盤。適合使用 Windows 10 或 11、希望 GUI 自動化能明確回報成功或失敗的使用者。
執行需求
僅限 Windows 10 或 11，需安裝商業版 agentfenster 應用程式，MCP 伺服器隨應用程式提供。本機 stdio 伺服器，以 agentfenster-mcp 啟動，需要應用程式自帶的 Python 3.11 或更新版本。desktop_task 的點擊迴圈需在應用程式中設定一個模型端點。未宣告任何環境變數或標頭。
安裝前請注意
此應用程式為商業閉源軟體，所有方案先提供 3 天試用，之後需付費。刪除、傳送、付款或安裝等高風險操作在 MCP 呼叫中預設會被拒絕，因此部分任務會被回報為受阻而非完成。設定的模型端點是唯一的網路流量，提示內容與從介面擷取的元素資料會傳送到該端點。操作會改變真實應用程式狀態。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 agentfenster，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

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.
