OpenSCAD MCP Server

What it does

Connects AI assistants to OpenSCAD, enabling the programmatic creation, rendering, and analysis of 3D CAD models. It allows the AI to generate .scad code and immediately visualize the result through renders.

Tools

• render_single: Render a single view with camera control and quality presets.
• render_perspectives: Render multiple standard views (front, back, top, etc.) in parallel.
• compare_renders: Provide side-by-side before/after renders for visual comparison.
• export_model: Export models to STL, 3MF, AMF, OFF, DXF, or SVG.
• create_model: Create new .scad files in the workspace.
• validate_scad: Syntax-check OpenSCAD code without a full render.
• analyze_model: Compute bounding box, dimensions, and triangle count.
