MCP Server / Scripting API for AI-driven automation (Claude, Cursor, etc.)
Ugur T.
Feature Request:
I'd like to request an official scripting API or Model Context Protocol (MCP) server integration for Plasticity.
What this would enable:
Right now, tools like Autodesk Fusion 360 can be controlled directly by AI assistants like Claude Code via an MCP server. This means you can describe a part in plain English — "create a 40mm bracket with two 5mm holes spaced 20mm apart" — and the AI executes every modeling step inside the CAD tool, just like a human would. The result is precise, editable geometry, not a mesh approximation.
Plasticity is already the best-in-class tool for artist-friendly NURBS and hard-surface modeling, built on the same Parasolid kernel as SolidWorks and Siemens NX. Adding an MCP interface would make it the most powerful AI-native CAD tool for creatives — a category no one else owns yet.
What I'm asking for, concretely:
A local MCP server (or equivalent scripting/automation API) that exposes Plasticity's core modeling operations — sketch creation, extrude, boolean, fillet, loft, sweep, export — so that AI coding assistants can drive Plasticity through natural language, the same way FusionMCP works for Fusion 360.
Since Plasticity's application layer is already open-source (LGPL), the community could likely build and maintain this — but an official hook or documented internal API would make it far more reliable and sustainable.
Why this matters:
The Claude Code + Fusion 360 MCP workflow is gaining serious traction (tens of thousands of views on YouTube tutorials in May 2026 alone). Plasticity users — especially indie designers, game artists, and product prototypers — are exactly the audience who would benefit most from this kind of AI acceleration. Without an API, they're forced to switch to Fusion 360 just to access this workflow, despite already owning Plasticity licenses.
This would be a major differentiator and a strong signal that Plasticity is ready to be part of the modern AI-assisted design stack.

Im looking for it too!
i asked to Claude to make a MCP Server but it can extrude, etc.

A MCP server/scripting API would de useful. I have created a tool call Watcher
that automatically converts STEP export from plasticity into FreeCAD parts,so that I can use the Assembly workbench for checking my models. So any changes I make in Plasticity I re-export and are auto relaoded in FreeCAD .

An official MCP/API would make this kind of workflow live instead of file-based.

It could function as a helpful AI assistant by analyzing objects from multiple perspectives to provide usage guidance. Direct surface generation might be challenging due to the complex mathematical logic required.

functional parity in CLI is the singular reason i will buy plasticity

I definitely do NOT want to see AI added to Plasticity. I use Plasticity specifically because I love doing the manual modeling of whatever idea I have. I love using sketch tools and manually drawing my idea line by line, then extruding it and seeing it come to life. If anyone wants to do things the easy way by skipping the part of CAD modeling that makes it CAD modeling, then please use those other corporate profit-inspired tools like Fusion360. Plasticity was not built on principles of "OMG, see what other tools are doing with AI. We should add that to Plasticity as well, or miss out on all the profits". Nick Kallen, I hope you're not one of those bros.

MrMoneyBagz I understand not wanting Plasticity to become another AI-first CAD tool. I also use tools like this because the manual modeling process is enjoyable and important.
But I don’t think exposing an interface for AI or automation is the same as forcing AI into the creative process. If the feature is optional, people who want to model everything manually can continue doing exactly that.
The value would be in making Plasticity controllable by external tools for those who need it: automation, scripting, repetitive tasks, accessibility, batch operations, or custom workflows. That does not invalidate the manual workflow.
So I think the concern should be less “AI must not exist” and more “AI must not replace or degrade the core hands-on Plasticity experience.”

I prefer new features outside of AI automation personally. I get the appeal for many folks. I just happen to not be one of them.
