pc-control（电脑控制）

PC Control — Remote Desktop Control

Control a Windows desktop from WSL/Linux via screenshots (mss) + mouse/keyboard simulation (pyautogui). A FastAPI server runs on Windows; a Python client calls it from WSL.

Setup

1. Configure config.json

Edit config.json in the skill directory. Set python_path to a Windows Python with pip:

{
  "server": {
    "host": "127.0.0.1",
    "port": 18888,
    "python_path": "C:\\Python312\\python.exe"
  },
  "powershell": "/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe",
  "auto_shutdown_minutes": 10,
  "screenshot": {
    "default_scale": 0.5,
    "default_quality": 50
  }
}

2. Install dependencies

python3 scripts/install.py

Installs fastapi uvicorn mss pyautogui pillow into the Windows Python.

Usage

Start the server

python3 scripts/launcher.py start

Take a screenshot and analyze

import sys; sys.path.insert(0, 'skills/pc-control/scripts')
from client import PCControl
pc = PCControl()
img_path = pc.screenshot(scale=0.5, quality=50)
# Use image analysis tool to understand the screen

Important: Screenshots are scaled. When clicking, divide target coordinates by the scale factor to get actual screen coordinates. E.g., if scale=0.5 and target is at (400, 300) in the image, click at (800, 600).

Execute actions

pc.click(x, y)                # Left click
pc.double_click(x, y)         # Double click
pc.right_click(x, y)          # Right click
pc.move(x, y)                 # Move cursor
pc.scroll(x, y, clicks)       # Scroll (negative = down)
pc.drag(x1, y1, x2, y2)      # Drag
pc.type_text("hello")         # Type text
pc.press("enter")             # Press key
pc.hotkey("ctrl", "c")        # Key combo

Verify after each action

Always screenshot after an action to confirm it worked before proceeding.

Stop the server

python3 scripts/launcher.py stop

Interaction Loop

screenshot → analyze → decide action → execute → screenshot verify → continue or done

Notes

• Server listens on localhost only with token auth (token auto-generated per session)
• Win+R → type app name → Enter is more reliable than clicking taskbar icons
• Wait 1–2 seconds after clicks before re-screenshotting
• Prefer CLI/PowerShell when available — use this only for GUI-only tasks
