Vibe Cading is a thing now. Describe a part, watch the LLM generate geometry, steer by eye until it looks right. 92 open source tools do exactly that, most built since MCP launched in late 2024.
The tools split on one question: who closes the feedback loop? In most, you do. You look at the render, describe what's wrong, the LLM tries again. In agent-driven tools, structured feedback returns to the LLM directly: scalar diagnostics, geometry properties, constraint violations. The agent corrects its own mistakes without you watching each iteration.
CAD Khana is our take on agent-driven vibe Cading. We chose code-CAD, where geometry is defined in code (Build123d, CadQuery, OpenSCAD), over wrapping a CAD application: diagnostics work cleaner directly against geometry, with no application object model in the way.
JSON diagnostics (interference, clearance, wall thickness, overhangs) come back after every Build123d build. The agent can also request a render and look at the geometry directly — multi-modal vision catches issues that don't surface as scalars. Assertions in the script become build failures, not warnings. Humans stay in the loop for taste and physical-world validation.
Agent-driven
Many wrap code-CAD libraries as MCP servers or Claude Code skills. Nearly as many add structured diagnostics on top of CAD applications: SolidWorks, AutoCAD, Inventor, Fusion 360, Onshape, Blender.

Human-directed
You inspect the result and steer the next iteration. Two shapes of tool live here: extensions to existing CAD applications (FreeCAD, Blender, Maya, AutoCAD, SolidWorks, Fusion 360, Onshape, Rhino/Grasshopper, SketchUp) for users who already know them, and standalone code-CAD tools for users who don't.
Blender is mesh-based animation software, not precision CAD, but blender-mcp is the most-starred 3D-tool MCP by a wide margin and sets the reference point for MCP tooling at scale. CADAM is the outlier in the other direction: a text-to-CAD web app rather than a server or extension.
