build123d MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for build123d MCP?
build123d MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package build123d-mcp was installed 2 607 times last week.
How do I connect build123d MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls build123d-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use build123d MCP?
The pypi package build123d-mcp was installed 2 607 times in the last week. Week over week that is +56%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is build123d MCP open source?
Yes — it is published under the Apache-2.0 licence, written in Python, 38 stars on GitHub and 36 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
