Pyautogui MCP

PyAutoGUI-MCP exposes MCP tools dynamically from the PyAutoGUI API. It does not manually reimplement or wrap each function: it auto-registers the available API.

Install with pip

pip install pyautogui-mcp

Run the server:

pyautogui-mcp --transport stdio
pyautogui-mcp --transport http --host 127.0.0.1 --port 8000

MCP client config example:

{
  "mcpServers": {
    "pyautogui-mcp": {
      "command": "pyautogui-mcp",
      "args": ["--transport", "stdio"]
    }
  }
}

Run with uv

Dependencies are declared in pyproject.toml, so uv can resolve and run directly:

{
  "mcpServers": {
    "pyautogui-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/full/path/to/pyautogui-mcp",
        "run",
        "python",
        "-m",
        "pyautogui_mcp"
      ]
    }
  }
}

You can also launch manually:

uv run python -m pyautogui_mcp --transport stdio
uv run python -m pyautogui_mcp --transport http --host 127.0.0.1 --port 8000

Use in your own project

Import only what you need and run it under your own server lifecycle:

from pyautogui_mcp import mcp, register_pyautogui_api

register_pyautogui_api(prefix="pyautogui_")
mcp.run()  # or mcp.run(transport="http", host="127.0.0.1", port=8000)

Other exports:

from pyautogui_mcp import pyautogui_diagnose, pyautogui_tools

Desktop control notes

• The server runs actions on the machine where it is launched (current desktop/display).
• PyAutoGUI requires a real GUI session; headless environments will fail.
• Safety: moving the mouse to a corner triggers the PyAutoGUI failsafe.
• Optional pause between actions via PYAUTOGUI_PAUSE=0.1.

Tool examples

Tool names are exposed with the default pyautogui_ prefix (configurable with --prefix).

pyautogui_position	none	cursor coordinates { "x": int, "y": int }
pyautogui_click	x, y, clicks, button, interval, duration	null (mouse click performed)
pyautogui_doubleClick	x, y, button, interval, duration	null (double-click performed)
pyautogui_rightClick	x, y, interval, duration	null (right-click performed)
