WinSight MCP

mcp-name: io.github.TheoEwzZer/winsight

Windows Screen Capture MCP Server — give Claude Code eyes on your Windows desktop.

WinSight is an MCP server that lets Claude Code capture your screen, manage windows, and launch applications on Windows.

Features

Screenshot the full screen, a specific region, or a specific window
Window capture uses Win32 PrintWindow API — captures the real window content even when it's behind other windows
List and inspect open windows and monitors (title, position, size, state, resolution)
Control windows — move, resize, minimize, maximize, restore, and focus
Launch applications and wait for their windows

Requirements

Windows 10/11
Python 3.10+

Quick Start

Option 1: uvx (recommended)

No install needed — runs directly:

config.json

{
  "mcpServers": {
    "winsight": {
      "command": "uvx",
      "args": ["winsight-mcp"]
    }
  }
}

Add this to your project's .mcp.json or ~/.claude/claude_desktop_config.json.

Option 2: pip install

Terminal

pip install winsight-mcp

Then configure:

config.json

{
  "mcpServers": {
    "winsight": {
      "command": "winsight-mcp"
    }
  }
}

Option 3: From source

bash

git clone https://github.com/TheoEwzZer/WinSight-MCP.git
cd WinSight-MCP
uv sync

config.json

{
  "mcpServers": {
    "winsight": {
      "command": "uv",
      "args": ["--directory", "/path/to/WinSight-MCP", "run", "winsight-mcp"]
    }
  }
}

Examples

Once the MCP server is connected, you can ask Claude Code things like:

"Take a screenshot of my screen"
"List all open windows"
"Capture the Notepad window"
"Open calculator and take a screenshot of it"
"Focus the Chrome window"
"Resize the app window to 800x600 and take a screenshot"
"Move the window to the top-left corner"
"What monitors do I have?"

Testing

The project has 112 tests covering all modules. Tests use mocks for Win32 APIs so they run on any platform.

Running tests

bash

uv run pytest

Test structure

text

tests/
  conftest.py              # Shared fixtures and Win32 stubs
  test_types.py            # TypedDict definitions validation
  test_screenshot.py       # Screen/region/window capture (mss, Win32 DC)
  test_window_manager.py   # Window listing, find, focus, resize, move, min/max/restore
  test_process_manager.py  # Application launch and window polling
  test_server.py           # MCP tool registration and integration

Adding tests

Put new tests in the matching test_<module>.py file
Use the shared fixtures from conftest.py (sample_window_info, mcp_server, fake_png_bytes)
Mock Win32 APIs with @patch("winsight_mcp.<module>.win32gui") — never call real Win32 functions in tests
For server integration tests, use the _call helper to invoke tools and _text to extract string results
