> lego-mcp — axel-jalonen-lego-mcp. Use this tool when you need to generate physically valid Lego models that adhere to real-world constraints. It solves problems of invalid or unbuildable designs by enforcing rules such as catalog-only parts and proper connections. The tool takes input from Large Language Models (LLMs) and outputs valid Lego models, making it ideal for applications where realistic and buildable Lego designs are required.
