Overview

What is Mcp Window Screenshooter?

Mcp Window Screenshooter is a cross-platform Model Context Protocol (MCP) server built in Python that enables AI agents to capture screenshots of specific application windows on Windows and Linux. It provides precise window-based capture for AI verification workflows, automated testing, and application monitoring, unlike traditional full-screen capture solutions.

How to use Mcp Window Screenshooter?

Install Python 3.12+, clone the repository, and install dependencies with pip install pywinctl pillow pywin32. Start the server with python server.py in STDIO mode, then configure an MCP client (such as Cursor IDE or Claude Desktop) to point to the server file. The server exposes three tools: capture_window, list_windows, and get_window_info.

Frequently asked questions

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"`.
