FAQ from Mcp Window Screenshooter

Which platforms does Mcp Window Screenshooter support?

Windows and Linux. Windows uses Win32 API with BitBlt and Graphics Capture API; Linux uses X11-based window capture.

How do I capture a specific window?

Use the capture_window tool with a window title (exact or partial). Optionally specify an output path, image format (PNG or JPEG), and JPEG quality. Returns base64 image data or a file path.

How can I see all available windows?

Call the list_windows tool. It returns an array of window objects with ID, title, position, and size information.

What happens if a window is not found?

The server returns a “window not found” error. You can first list windows with list_windows to verify the exact title, try partial matching, or ensure the window is visible.

How do I configure Mcp Window Screenshooter with Cursor IDE?

Add an entry in your MCP configuration file with command "python", args ["server.py"], and the correct working directory, using "transport": "stdio".
