# cad-mcp

> Use this tool when you need to analyze and query CAD geometry from STEP files using natural language. It solves problems related to part and assembly inspection, dimension verification, and mass property calculation, enabling LLMs to reason about CAD data. The cad-mcp tool takes STEP files as input and provides outputs in response to natural language queries about the geometry.
