take_screenshotLABSCO SUMMARY
The compression is the part that makes it work at all.
A screenshot from a modern monitor is far too large to hand to a model directly. This one steps the image down progressively — 1920px, then 1280px, then 800px — until it fits under 1MB, adjusting quality along the way, which is why a full-desktop capture returns rather than failing. If a capture still will not come back, lowering the quality parameter is the documented first move. Everything is processed locally with no network transmission.
What it is
A capture bridge for developers working in WSL against a Windows desktop. It drives PowerShell to grab monitors, windows or the clipboard, then processes the image so it can actually be returned to a model.
What you get
take_screenshotcaptures all monitors, the primary monitor, or a specific monitor by number- The same tool targets a window by title with partial matching, or by process name, with

- Paths work in both WSL and Windows form
Requirements
Windows 10 or 11 with WSL2, Node.js 18.0.0 or higher, and PowerShell, which ships with Windows. Clone and install; the client launches it through wsl --cd pointed at the install directory. Published as wslsnapit-mcp, version 2.2.0.
Setup effort
Build from source — git clone https://github.com/peterparker57/WSLSnapit-MCP.git
USE CASES
01
Showing the assistant what your app looks like
Capture the window by title and hand the image straight over, without saving a file first.
02
Capturing one screen out of several
Name the monitor by number instead of grabbing the whole desktop and cropping.
03
Getting a copied error into the conversation
Read the clipboard and let it work out whether it is text or an image.
04
Keeping a record of a UI state
Save the capture to a folder with the name you want rather than returning it inline.
