CursorTouchMCP SERVER

Windows-MCP

Give any LLM control of a Windows desktop — click, type, launch apps, run PowerShell, read the registry — using the accessibility tree, no vision model required.

by CursorTouch ↗Desktop & OS AutomationCommunity

LABSCO SUMMARY

Reading the accessibility tree instead of pixels is why any model can drive it — and where the limits are.

No vision model, no fine-tuning, and typical action-to-action latency of 0.2 to 0.5 secs. The same choice sets the boundaries the README publishes: selecting part of a paragraph is not supported because it comes from the a11y tree, Type-Tool writes a program as a whole file rather than typing into an IDE, and games are out. Everything below PowerShell, FileSystem and Registry is full system access — use --tools or --exclude-tools when exposing it.

What it is

A Windows automation server that works off the accessibility tree rather than screenshots and a fine-tuned vision model, so it runs with any LLM. It supports Windows 7 through 11, ships over stdio or HTTP, and carries a real security layer for the remote case.

What you get

  • Input: clicking, typing with optional clearing, scrolling regions or windows, mouse movement and deterministic drags with an explicit start point, and keyboard shortcuts — Click, Type, Scroll, Move, Shortcut
  • Two capture modes: a fast screenshot-first view with cursor position and window list that skips UI-tree extraction, and a full snapshot with interactive element ids, scrollable regions and browser DOM extraction — Screenshot, Snapshot
  • Both capture tools take a display list or a region rectangle, so you can inspect one area instead of the whole desktop and pay fewer tokens for it
  • Waiting that is not a fixed sleep: poll until text, a window, an element or a focused element appears — Wait, WaitFor
  • Applications and windows launched by Start Menu name or by executable path with separated argv, then resized, moved and switched — App
  • System reach: PowerShell commands, the file system, the clipboard, the process list, toast notifications and the registry — PowerShell, FileSystem, Clipboard, Process, Notification, Registry
  • Bulk helpers for multi-file selection and multi-field entry, plus whole-page web scraping and display layout with DPI and scale metadata — MultiSelect, MultiEdit, Scrape, DisplayInventory
  • A DOM mode for browser automation that filters out browser chrome, supporting Chrome, Edge and Firefox
  • Security for remote use: an auth key, an IP allowlist, CORS origins, TLS, OAuth 2.0 with PKCE, SSRF protection, and per-tool allow and deny lists

Requirements

Windows, Python 3.13+ and uv. Run with uvx windows-mcp serve over stdio, or add --transport sse or --transport streamable-http with a host and port for network access. windows-mcp install registers a per-user scheduled task that starts it now and at every login. Configuration can live in ~/.windows-mcp/config.toml instead of flags. English as the Windows display language is preferred; otherwise disable the App tool. Version 0.8.5. MIT licensed.

Setup effort

One command — uvx windows-mcp serve
