CAiD MCP Server

Connects Claude to CAiD's 3D modeling engine with 107 validated geometry operations across primitives, booleans, fillets, assemblies, and STL export. Built on OpenCASCADE with a ForgeResult layer that catches silent boolean failures by tracking volume and surface area after every operation. The query tools let Claude inspect edges and faces before modifying them, solving the blind fillet problem where LLMs guess which edge to target. Includes index based selection, section cuts, exploded views, and a scripting escape hatch for raw OCP calls. All exports land in a configurable output directory as STL, STEP, or SVG previews. Returns structured Pydantic models starting in v0.6.0 so agents can read bounding boxes and volumes directly instead of parsing text.
