Creo MCP servers and AI agent skills
Creo Parametric has a handful of community MCP servers and no official one. The fuller projects compile a Creo Toolkit program that runs inside Creo on Windows and build native, editable features, saving and re-checking the model after each change. Smaller ones open models, export STEP or PDF and read parameters, one of them together with Windchill. Expect a C or C++ build step, a matching Toolkit SDK and a PTC licence; documentation is often in Chinese.
- No official PTC server yet.
- 4 MCP servers listed.

How AI connects to Creo
An MCP server or skill can only do what Creo lets programs do. Creo exposes 3 automation interfaces:
- Creo TOOLKIT (C/C++) (Other): Creo's C and C++ Toolkit reaches features, sketches, assemblies and drawings from compiled code, and the two largest Creo MCP servers are built on it: one wraps it as an executor driven from Python, the other loads a Pro/TOOLKIT DLL into each Creo process and talks to it over a named pipe. Both need the Toolkit SDK that matches your Creo release and the Microsoft C++ build tools, and both must be rebuilt or rechecked when you upgrade Creo.
- Creo Object TOOLKIT Java and J-Link (Java): The Java route is documented in PTC's Creo Object TOOLKIT Java help centre; J-Link is installed automatically with Object TOOLKIT Java. One listed server uses J-Link or OTK to open models, export STEP and drawing PDFs and read parameters. Java access suits read-mostly integrations that sit next to a PLM system rather than heavy feature creation. Documentation
- CREOSON (open-source JSON bridge) (REST API): CREOSON is an MIT-licensed server that automates Creo Parametric 3.0 and later through simple JSON transactions, with over 190 functions, and its site now pitches it to AI agents. A Python client, creopyson, wraps it. It is an easier entry point than compiling Toolkit code, though several Creo MCP experiments built on it are too early to list here. Documentation
What PTC offers
PTC builds AI into Creo itself rather than shipping an MCP server. Creo 13 brought a chat assistant (Advise) for how-to help and troubleshooting for all users, an Assist capability in beta that reads the open model and can add design intent, and an Automate capability in alpha that proposes changes and builds them in a sandbox for comparison. PTC's only MCP servers so far are for Onshape and Windchill.

What you can do with Creo and AI
- Build native Creo features, such as sketches, extrusions, revolves, holes, rounds, shells and sheet metal, and confirm each change by saving, reloading and comparing the model.
- Create assemblies and drawings and edit parameters and relations in an existing model.
- Read model parameters and dimensions, change a dimension with old-value checks, and roll back if the regeneration fails.
- Open a Creo model listed in Windchill and export STEP or a drawing PDF for a supplier.
- Report mass properties and export STEP from the active session.

Installing
The listings here document setup for ChatGPT Desktop, Claude Desktop, Codex, Cursor and WorkBuddy. Install steps, copied from each project's own documentation, are on each listing's page. Most Creo integrations run on your own computer next to Creo, so you need Creo installed and licensed on the same machine unless the listing says otherwise.

Questions
Is there an official Creo MCP server?
No. PTC has MCP servers for Onshape (FeatureScript, early access) and for the Windchill AI Assistant, but none for Creo as of 4 November 2026. Its Creo AI work is the built-in Advise, Assist and Automate features in Creo 13.
Can Claude build features in Creo Parametric?
Yes, with a Toolkit-based community server on the Windows PC where Creo runs. You compile its Creo component against your Toolkit SDK, start Creo, and register the server in your client. Claude then creates native features you can edit afterwards.
Which Creo versions work?
The most complete server supports Creo Parametric 9, 10 and 12 and was released against 12.4. Other projects don't state a version and need a matching Pro/TOOLKIT or J-Link installation.
Do I need a Creo Toolkit licence?
The listed servers say you must supply Creo, the Toolkit SDK and a valid PTC licence yourself. Check with PTC or your reseller which Toolkit or Object TOOLKIT licence your use needs.
AI-generated models, drawings and results must be checked by a qualified engineer before use.
