# Computer Control MCP ### MCP server that provides computer control capabilities, like mouse, keyboard, OCR, etc. using PyAutoGUI, RapidOCR, ONNXRuntime. Similar to 'computer-use' by Anthropic. With Zero External Dependencies.

--- ![MCP Computer Control Demo](https://github.com/AB498/computer-control-mcp/blob/main/demonstration.gif?raw=true) ## Quick Usage (MCP Setup Using `uvx`) ***Note:** Running `uvx computer-control-mcp@latest` for the first time will download python dependencies (around 70MB) which may take some time. Recommended to run this in a terminal before using it as MCP. Subsequent runs will be instant.* ```json { "mcpServers": { "computer-control-mcp": { "command": "uvx", "args": ["computer-control-mcp@latest"] } } } ``` OR install globally with `pip`: ```bash pip install computer-control-mcp ``` Then run the server with: ```bash computer-control-mcp # instead of uvx computer-control-mcp, so you can use the latest version, also you can `uv cache clean` to clear the cache and `uvx` again to use latest version. ``` ## Features - Control mouse movements and clicks - Type text at the current cursor position - Take screenshots of the entire screen or specific windows with optional saving to downloads directory - Extract text from screenshots using OCR (Optical Character Recognition) - List and activate windows - Press keyboard keys - Drag and drop operations - Enhanced screenshot capture for GPU-accelerated windows (Windows only) ## Note on GPU-accelerated Windows Traditional screenshot methods like GDI/PrintWindow fail to capture GPU-accelerated windows, resulting in black screens. This impacts games, media players, Electron apps, browsers with GPU acceleration, streaming software, and CAD tools. Use WGC through `take_screenshot` tool's flag or `ENV` variable ## Configuration ### Custom Screenshot Directory By default, screenshots are saved to the OS downloads directory. You can customize this by setting the `COMPUTER_CONTROL_MCP_SCREENSHOT_DIR` environment variable: ```json { "mcpServers": { "computer-control-mcp": { "command": "uvx", "args": ["computer-control-mcp@latest"], "env": { "COMPUTER_CONTROL_MCP_SCREENSHOT_DIR": "C:\\Users\\YourName\\Pictures\\Screenshots" } } } } ``` Or set it system-wide: ```bash # Windows (PowerShell) $env:COMPUTER_CONTROL_MCP_SCREENSHOT_DIR = "C:\Users\YourName\Pictures\Screenshots" # macOS/Linux export COMPUTER_CONTROL_MCP_SCREENSHOT_DIR="/home/yourname/Pictures/Screenshots" ``` If the specified directory doesn't exist, the server will fall back to the default downloads directory. ### Automatic WGC for Specific Windows You can configure the system to automatically use Windows Graphics Capture (WGC) for specific windows by setting the `COMPUTER_CONTROL_MCP_WGC_PATTERNS` environment variable. This variable should contain comma-separated patterns that match window titles: ```json { "mcpServers": { "computer-control-mcp": { "command": "uvx", "args": ["computer-control-mcp@latest"], "env": { "COMPUTER_CONTROL_MCP_WGC_PATTERNS": "obs, discord, game, steam" } } } } ``` Or set it system-wide: ```bash # Windows (PowerShell) $env:COMPUTER_CONTROL_MCP_WGC_PATTERNS = "obs, discord, game, steam" # macOS/Linux export COMPUTER_CONTROL_MCP_WGC_PATTERNS="obs, discord, game, steam" ``` When this variable is set, any window whose title contains any of the specified patterns will automatically use WGC for screenshot capture, eliminating black screens for GPU-accelerated applications. ## Available Tools ### Mouse Control - `click_screen(x: int, y: int)`: Click at specified screen coordinates - `move_mouse(x: int, y: int)`: Move mouse cursor to specified coordinates - `drag_mouse(from_x: int, from_y: int, to_x: int, to_y: int, duration: float = 0.5)`: Drag mouse from one position to another - `mouse_down(button: str = "left")`: Hold down a mouse button ('left', 'right', 'middle') - `mouse_up(button: str = "left")`: Release a mouse button ('left', 'right', 'middle') ### Keyboard Control - `type_text(text: str)`: Type the specified text at current cursor position - `press_key(key: str)`: Press a specified keyboard key - `key_down(key: str)`: Hold down a specific keyboard key until released - `key_up(key: str)`: Release a specific keyboard key - `press_keys(keys: Union[str, List[Union[str, List[str]]]])`: Press keyboard keys (supports single keys, sequences, and combinations) ### Screen and Window Management - `take_screenshot(title_pattern: str = None, use_regex: bool = False, threshold: int = 60, scale_percent_for_ocr: int = None, save_to_downloads: bool = False, use_wgc: bool = False)`: Capture screen or window - `take_screenshot_with_ocr(title_pattern: str = None, use_regex: bool = False, threshold: int = 10, scale_percent_for_ocr: int = None, save_to_downloads: bool = False)`: Extract adn return text with coordinates using OCR from screen or window - `get_screen_size()`: Get current screen resolution - `list_windows()`: List all open windows - `activate_window(title_pattern: str, use_regex: bool = False, threshold: int = 60)`: Bring specified window to foreground - `wait_milliseconds(milliseconds: int)`: Wait for a specified number of milliseconds ## Development ### Setting up the Development Environment ```bash # Clone the repository git clone https://github.com/AB498/computer-control-mcp.git cd computer-control-mcp # Build/Run: # 1. Install in development mode | Meaning that your edits to source code will be reflected in the installed package. pip install -e . # Then Start server | This is equivalent to `uvx computer-control-mcp@latest` just the local code is used computer-control-mcp # -- OR -- # 2. Build after `pip install hatch` | This needs version increment in orer to reflect code changes hatch build # Windows $latest = Get-ChildItem .\dist\*.whl | Sort-Object LastWriteTime -Descending | Select-Object -First 1 pip install $latest.FullName --upgrade # Non-windows pip install dist/*.whl --upgrade # Run computer-control-mcp ``` ### Running Tests ```bash python -m pytest ``` ## API Reference See the [API Reference](docs/api.md) for detailed information about the available functions and classes. ## License MIT ## For more information or help - [Email (abcd49800@gmail.com)](mailto:abcd49800@gmail.com) - [Discord (CodePlayground)](https://discord.gg/ZeeqSBpjU2)
