Best MCP servers for 3D and CAD

We found 240 MCP servers for 3D and CAD in the catalog; these are the 15 that rank highest. The order comes from our rank, which weighs adoption, freshness, documentation and publisher identity. Nobody can pay for a place on this list. Pascal 3D Editor, Unity MCP and SceneView/mcp lead it. Pascal 3D Editor and Bitbybit CAD MCP are published by the company that makes them. Pascal 3D Editor has the most GitHub stars here (25,086). 15 of the 15 had activity in the last 30 days. Remote servers need no local install; local ones run on your machine and can reach local files. Each entry lists why it made the list and links to its install page.
