JupyterCAD MCP server

This is a small helper that connects your AI assistant to JupyterCAD, a program for making 3D models. You describe what you want, like a box or a cylinder, and the AI draws it in your CAD file for you. It is handy if you use JupyterCAD but find clicking through menus slow or fiddly.

What this MCP server does

You type a request, like add a box that is 1 by 1 by 1. Your AI reads that and picks the right action from this helper. The helper then talks to JupyterCAD and makes the change in your CAD document. You see the new shape appear in JupyterLab, and the AI tells you what it did. It can also read your current design, remove or rename things, and combine shapes.

What you can do with it

• Add basic shapes like boxes, cones, cylinders, spheres, and tori
• Read the current contents of your CAD file
• Remove or rename objects in the design
• Combine two shapes with cut, fuse, or intersect
• Round or bevel edges with fillet and chamfer
• Add notes and annotations to the document
• Change the color or visibility of an object

Try asking your AI

• “Add a box with width 2, height 2 and depth 2”
• “Remove the sphere I added earlier”
• “Fuse the box and the cylinder together”
• “Make the cone red and hide the torus”

What it gives back to you

You get short answers in the chat, like a confirmation that a shape was added or removed. The real result shows up in JupyterCAD, where the new or changed shape appears in your design. If you ask it to read the file, it gives you a list of what is currently in the document. It can also tell you the names and details of the objects it sees.

Before you start

Who it's for

People who use JupyterCAD for 3D design and want to build or tweak models by describing them instead of clicking through menus.
