Modulor runs on your own machine — the client starts it, so there is no endpoint to ping. 154 installs a week from pypi. Last commit 12 Jun 2026.
Agent-native CAD: draw plans, model 3D, render checks, export DXF/SVG/STL/GLB/IFC, import DXF.
What the code does

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.
return eval(code, env, {"x": x, "y": y, "z": z}) # noqa: S307

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.
