Official

As of October 2026, PTC publishes an official Onshape FeatureScript MCP Server, announced August 13, 2026 and offered through the Onshape Labs early-access program. It is a remote HTTP server that lets coding AI tools write, run and debug FeatureScript inside Onshape documents. It is FeatureScript-focused, not a general Onshape document server, and its auth and plan details are not published.
