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
PrintWindowAPI — 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:
{
"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
pip install winsight-mcp
Then configure:
{
"mcpServers": {
"winsight": {
"command": "winsight-mcp"
}
}
}
Option 3: From source
git clone https://github.com/TheoEwzZer/WinSight-MCP.git
cd WinSight-MCP
uv sync
{
"mcpServers": {
"winsight": {
"command": "uv",
"args": ["--directory", "/path/to/WinSight-MCP", "run", "winsight-mcp"]
}
}
}

Testing
The project has 112 tests covering all modules. Tests use mocks for Win32 APIs so they run on any platform.
Running tests
uv run pytest
Test structure
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>.pyfile - 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
_callhelper to invoke tools and_textto extract string results
