What Desktop Touch MCP does

Windows computer-use MCP server: drive any desktop app via semantic discover-then-act targeting (entities + leases, not pixel coordinates), with per-action perception guards, a native Rust UIA engine, Chrome CDP, and Key Locker credential autofill for ssh/sudo password prompts. Works with Claude, Cursor, and any MCP client.

[日本語](README.ja.md)

**Computer-use MCP server for Windows.** Lets Claude, Cursor, or any MCP client see and operate your Windows 10/11 desktop — screenshots, UI Automation, Chrome CDP, keyboard / mouse, terminal — with **semantic discover-then-act targeting** that avoids pixel-coordinate guessing, and **per-action perception guards** that catch wrong-window typing before it happens.

32 tools, native Rust engine (UIA in 2 ms), zero-config PowerShell fallback, full CJK support, MIT licensed. Add the snippet above to your Claude / Cursor / VS Code Copilot config and Claude can drive Notepad, Excel, Chrome, Windows Terminal, and any other app on your machine.

**Why this over pixel-clicking?** Two ideas run through every tool: **discover-then-act** — `desktop_discover` returns interactive entities with short-lived leases instead of raw coordinates, so `desktop_act` operates on *what* you mean, not *where* it was — and **per-action perception guards** that verify the target window's identity and bounds before input lands, catching wrong-window typing and stale-coordinate clicks before they happen.

Under the hood: an **82× average speedup** from the Rust native engine (UIA focus queries in 2 ms, SSE2-accelerated image diffing at 13–15×), with a transparent PowerShell fallback when the engine is absent. The npm launcher fetches only the GitHub Release tag matching the installed version and verifies the Windows runtime zip before extraction.

Features

⚡ High-performance Rust Native Core — The UIA bridge and image-diff engine are written in Rust (napi-rs + windows-rs) and loaded as a native .node addon. Direct COM calls from a dedicated MTA thread eliminate PowerShell process spawning — getFocusedElement co
