AI Agent CAD Tool 1

Open-source CAD tool for AI agents to design and validate 3D parts. agentcad is an open-source CAD tool designed specifically for AI agents, functioning as a Model Context Protocol (MCP) server and Command Line Interface (CLI). It enables coding agents like Claude Code, Cursor, and Windsurf to write build123d or CadQuery scripts, automatically validate geometry, catch broken code, and render models from multiple angles. This creates a tight feedback loop that helps AI agents fix their own design mistakes and converge on watertight, dimensionally correct, and printable 3D geometry without human intervention, ultimately exporting files in STEP, STL, GLB, and OBJ formats.
