CAD MCP servers: what to know before you pick one
What's the most popular MCP server for CAD?
Among community builds, the most-starred on GitHub are Bitbybit CAD MCP (★ 207), FreeCAD MCP (★ 62) and best-cad-mcp (★ 34). If you want one that passed every check, Bitbybit CAD MCP did.
Is it safe to give an AI a CAD MCP server?
On registry checks, 23 of 31 come out clean. We also read the code or live tool list of 22 of them without running anything, and 1 raised a warning worth reading, such as an install script or text aimed at the AI. Treat a pass as "nothing found", and give any server the least access that works.
Is a Claude skill better than an MCP server for CAD?
An MCP server gives the AI new tools, such as reaching CAD itself. A skill only teaches it how to do a task with tools it already has. There are 23 Claude skills for CAD if that fits better.
How fresh are these CAD MCP servers?
23 of the 31 were updated in the 30 days before 31 Oct 2026. The latest was onshape, on 27 October.
How do I add a CAD MCP server to Claude?
To connect CAD through Bitbybit CAD MCP, run this in a terminal: claude mcp add --transport http cad https://mcp.bitbybit.dev/mcp. Pin the version shown before you rely on it.
Do I have to install a CAD MCP server?
8 can run hosted, so you only paste a URL into Claude, Cursor or VS Code. The 24 that run locally ship as 9 MCPB bundle, 7 npm, 7 PyPI and 1 Docker packages.
