AI integrations for mechanical design and manufacturing
Tresca tracks 15 tools in this field. 14 have at least one listed MCP server or agent skill.
Mechanical CAD has a broad spread of AI integrations. Autodesk publishes official MCP servers for Fusion, covering the desktop app, Fusion data in the cloud and a headless compute service in beta, and PTC offers an early-access FeatureScript server for Onshape. The CadQuery project publishes its own server, and code-first CAD tools such as build123d and OpenSCAD suit agents well because models are plain scripts.
For SOLIDWORKS, Siemens NX, CATIA, Creo and Inventor, every server is a community project, usually driving the program through its COM, NX Open or J-Link API on Windows. FreeCAD has several servers and works on any operating system. PLM coverage is light: PTC's Windchill assistant server answers from documentation, and Teamcenter has one community server. Check each listing's supported versions, because CAD APIs change between releases.

Questions
Which CAD vendors publish official MCP servers?
Autodesk publishes Fusion servers for the desktop app, cloud data and a compute service in beta, and PTC has an early-access FeatureScript server for Onshape. SOLIDWORKS, CATIA, NX, Creo and Inventor have community servers only.
Is there a free option that runs on any operating system?
FreeCAD has several community servers and runs on Windows, macOS and Linux, and code-first tools such as CadQuery, build123d and OpenSCAD suit agents because models are plain scripts.
Do these servers work with every CAD version?
No. CAD APIs change between releases, so each listing records the versions its author documents. Check that yours is covered before installing.
