arcade-mcp vs build123d-mcp

Q: Which is better, arcade-mcp or build123d-mcp?

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

arcade-mcp: The Arcade MCP Server Framework is a Python framework for building custom Multi-modal Communication Protocol (MCP) servers. It simplifies the creation of AI-callable tools, handling aspects like secrets, authentication, and different communication transports.; 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.
