⚠️ This server can fully control your Windows machine. See docs/security.md for:

• Security warning and dangerous capabilities
• Elevation & UIPI (Admin vs Non-Admin)
• Data collection & privacy controls
• Agent configuration

This executable can fully control the Windows machine it runs on. It exposes these capabilities to any connected AI agent:

• Read anything on screen — screenshot, OCR, screen recording
• Control input — mouse clicks/moves, keyboard typing, key combos
• Read and write clipboard — steal or replace clipboard contents
• Kill processes, launch executables, shutdown/restart the machine
• Change system audio, volume, mute, default devices
• Enumerate and interact with windows — move, resize, close, find
• Read network config, ping hosts, enumerate adapters
• Read disk usage, battery state, display modes
• Automate UI elements via UI Automation (find/invoke buttons, read text)

Treat this binary with the same caution as a remote-admin tool. Only connect it to MCP clients you trust. The AI agent receiving these tools has equivalent access to a logged-in user at the keyboard. Do not expose it over a network without authentication, and never run it on a machine where you wouldn't let a remote user operate the mouse and keyboard.

Elevation & UIPI (Admin vs Non-Admin)

Windows UIPI (User Interface Privilege Isolation) silently blocks input from non-elevated processes targeting elevated (Administrator) windows.

If you run an app as Administrator (game installers, system tools, some games like HTGame.exe): → You must also run mcp-server.exe as Administrator for mouse clicks and keyboard input to reach it.

Without elevation:

• Keyboard (type, key_press, type_and_submit): returns a clear warning — UIPI blocks SendInput with KEYEVENTF_UNICODE
• Mouse (click, scroll, drag): silently fails — no error, no feedback. The cursor moves (via SetCursorPos) but the click never fires

To run elevated: right-click your terminal/launcher → "Run as Administrator" → start mcp-server.exe. Or set your MCP client config to launch it through an admin shell.

The good news: this is a Windows security feature, not a bug. Normal (non-admin) applications work fine without elevation — browsers, terminals, editors, chat apps, file explorers, most games. You only need admin mode when targeting admin windows.

Data Collection & Privacy Controls

The server has no telemetry, no network calls, no data exfiltration. All collected data stays in %APPDATA%/go-mcp-computer-use/training/. But users have full runtime control:

Goal	How
Stop all screenshot saving	set_config with training_enabled: false — disables auto-saves from actions AND the background watcher instantly
Re-enable data collection	set_config with training_enabled: true
Stop the background watcher	set_config with watcher_enabled: false — or onnx_watch_stop
Start the background watcher	set_config with watcher_enabled: true — uses interval from config or watcher_interval_seconds
Change watcher frequency	set_config with watcher_interval_seconds: 10 — restarts watcher with new interval if running
Disable ML prior learning	set_config with prior_adjustment: false
Delete noise samples	training_cleanup_noise with max_age_hours: 0 — purges low-quality frames
Clear cached element data	memory_forget with scope: ui — removes cached ONNX detection positions
Inspect collected data	training_stats — see counts, sources, disk usage
Export collected data	export_yolo_dataset — dump all images + labels to a directory
Persistent disable	Set "training_enabled": false in ~/.config/go-mcp-computer-use/config.json

The set_config tool can be called by the AI agent or directly by the user via their MCP client. All changes persist to disk and survive server restarts.

For maximum privacy: set training_enabled: false in config before starting the server.

Agent Configuration

{
  "mcpServers": {
    "computer-use": {
      "command": "C:\\tools\\mcp-server.exe"
    }
  }
}
