PTC Adds FeatureScript MCP Server to Onshape

August 13, 2026
PTC has added FeatureScript MCP Server to Onshape, letting engineers create custom CAD features with natural language and AI assistance.

PTC announced in a press release the availability of FeatureScript MCP Server for its Onshape CAD and PDM platform. The capability is available through Onshape Labs and lets engineers create custom CAD features using natural language and AI.

Engineers describe the function they need, and AI helps build, test, debug, and refine the custom feature in FeatureScript. FeatureScript is Onshape's programming language for CAD automation, used to capture engineering knowledge, automate repetitive design tasks, and create custom design tools.

The new server is built on the Model Context Protocol and connects Onshape FeatureScript code with coding large language models such as Claude, ChatGPT, and Gemini. PTC said the capability can help teams turn design practices into reusable tools that can be shared across projects.
