BOSTON, MA, Aug 17, 2026 – PTC has released a FeatureScript MCP Server for Onshape CAD and PDM platform that lets engineers build custom CAD features by describing them in natural language. Available through Onshape Labs, the server connects Onshape FeatureScript code to coding LLMs such as Claude, ChatGPT, and Gemini over the Model Context Protocol (MCP).
Engineers describe the functionality they need; AI then builds, tests, debugs, and refines the custom feature in FeatureScript until it works as intended. FeatureScript is Onshape’s programming language for CAD automation.
PTC listed three workflows for the FeatureScript MCP server:
- Engineers who do not write code can create custom CAD features in natural language rather than code.
- Proven design practices become reusable tools that can be shared across teams and projects
- Teams can build custom engineering tool sets they can reuse without repeated prompting, ongoing AI interactions, or recurring AI costs.
“The future of AI in CAD is not simply text-to-CAD, but text-to-code-to-CAD,” said David Katzman, EVP and general manager of Onshape and Arena at PTC. “The real value of AI is helping engineers turn proven ideas into tools they can use again and again. With the new FeatureScript MCP Server, Onshape has become the most customizable production CAD system, empowering all users to build engineering capabilities tailored to their company’s products and processes. ”
“The significance of this announcement isn’t that AI can generate another CAD model,” said Jeff Hojlo, research vice president, industrial ecosystems, engineering & product innovation strategies at IDC. “It’s that AI is being used to create engineering capability. As organizations look to apply AI in engineering, the focus is shifting from generating outputs to capturing and operationalizing engineering expertise.”
The release is part of PTC’s Intelligent Product Lifecycle program, which centers on a product data foundation that extends across the enterprise, and accelerate AI-driven transformation.
