b123d-print runs on your own machine — the client starts it, so there is no endpoint to ping. 5 630 installs a week from pypi. Last commit 25 Oct 2026.
Vibe CAD for 3D printing: design, check and export printable parts with build123d.
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.
res = eval(expr, env) # noqa: S307 - our own generated expression, on the caller's part
subprocess.run(["git", "clone", "-q", "--filter=blob:none", "--no-checkout", REPO, str(dest)], check=True)
p.add_argument("--authorized-keys", help="file to add it to (default: ~/.ssh/authorized_keys)")

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.
