OpenSCAD

Overview

OpenSCAD is an MCP server that renders STL and PNG outputs from OpenSCAD code. It lets AI assistants work with 3D modeling directly, calling OpenSCAD as a native tool rather than requiring manual workflow steps between applications.

The server runs locally on your machine via the npm package openscad-mcp-server, installed with npx -y openscad-mcp-server. It communicates over stdio and requires no authentication or external credentials. Version v1.0.5 is available under the MIT license, with source code hosted at fboldo/openscad-mcp-server on GitHub.

OpenSCAD is listed in the Development category on mcp.site and works with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you can claim this listing to verify ownership and keep information up to date.
