Model Lab runs on your own machine — the client starts it, so there is no endpoint to ping. 128 installs a week from pypi. Last commit 21 Oct 2026.
Draws rigged game gun models in Blender from parameters, checked against the real gun
What the code does
We read the source, 2 d ago · rules 995398eba69f
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
plat = __import__(PLATFORMS[job["platform"]])
fbx = os.path.join(OUT, "A_%s_%s.fbx" % (NAME, name))
txt = subprocess.run(["powershell", "-NoProfile", "-Command", ps], capture_output=True, text=True, timeout=60).stdout

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

MODELLAB_BLENDER (Blender's executable (4.2 or later), if it is not on the PATH or in the usual install folder), MODELLAB_OUT (The only folder Model Lab writes to (builds, clips, comparisons); defaults to ~/.modellab), MODELLAB_WAIT_FOR (Optional process names that hold the machine (e.g. UnrealEditor.exe,blender.exe); a build refuses to start while one runs).
