Connect Claude, ChatGPT, and Grok (respective accounts needed separately) to Autodesk Inventor running on your own Windows machine. Read the open part, assembly or drawing, drive dimensions and parameters, build features, place components, pull drawing views and GD&T callouts, and export STEP, DXF or STL — while your models stay on your machine.
The Inventor adapter answers 57 of the 86 tools in the ForgeMCP canonical set — the same canonical names the SolidWorks adapter answers to, so a prompt written against one reads the same against the other. The words an engineer actually uses are aliased onto the tools, so asking for "iProperties", "Work Plane" or "Circular Pattern" lands on the right one. The cards below group the coverage rather than listing every signature, and because this is a beta, names and signatures can still change between builds.
Alongside those: mass properties, measured distances between selected entities, material and unit reads and writes, configuration listing and activation, undo with its stack, and a PNG screenshot of the 3D view from the current camera or any standard or isometric one. Inventor's own scripting is reachable as an opt-in escape hatch — it stays off until you enable it in the server config, and the capability reports itself as gated until you do.
The Inventor MCP server runs as a local bridge on your own workstation and drives the Inventor session already open there. Parts, assemblies, drawings and their referenced files are read locally — only the specific answer your AI asked for is returned. Raw geometry and source files never leave your machine. See local bridge architecture for the full shape of how this works.
The Windows installer works with any MCP-capable client, and the Claude Desktop bundle is Claude Desktop's own install format — pick whichever matches the assistant you already use. Separately, every workspace has one connector URL, shown on your dashboard, which you add as a custom connector in Claude, ChatGPT, Perplexity or Grok to reach ForgeMCP's hosted engineering tools. Sign-in uses your own ForgeMCP account in both cases, and there are no API keys to enter anywhere.
"Open the bracket, set Thickness to 6 mm, rebuild it, and tell me what that did to the mass." The dimension's previous value is read before it is written and returned alongside the rebuild result, so the assistant can confirm the change and revert it — and the part is not saved unless you save it. See parametric CAD automation for why a named-dimension edit like this is a contained, reviewable kind of change.
"Export the flat pattern of this sheet-metal part to DXF and give me the file size." The DXF is written ready for laser or waterjet cutting and the path and byte size come back; if the part has no flat pattern, the answer says so instead of guessing.
Inventor data that lives in Autodesk's cloud rather than on your workstation is reached through a separate hosted connector for Autodesk Platform Services, signed in with your own Autodesk account. It lists hubs, projects and top-level folders, walks folder contents and file version history, and runs Model Derivative translations — reading back the manifest, the metadata views, object properties and the object tree. Because it talks to Autodesk's cloud rather than to an application on your machine, it is a cloud connector and needs no Desktop Connector add-on.
