build123d-mcp vs solidworks-automation-skill

Q: Which is better, build123d-mcp or solidworks-automation-skill?

By GitHub stars, solidworks-automation-skill has more community adoption, but the best choice depends on your specific use case.

build123d-mcp: build123d-mcp is an MCP server that exposes build123d CAD operations as tools, allowing AI assistants to interactively build, inspect, and iterate on 3D geometry. It closes the feedback loop for AI writing build123d scripts, enabling them to create geometry, render views, query dimensions, and catch errors incrementally.; solidworks-automation-skill: A Skill, MCP server and desktop app that let coding agents drive real SolidWorks and AutoCAD through natural language. Results are verified before delivery, with recovery decisions and structured execution traces.
