agentcad CAD tool for AI agents. Give your coding agent the ability to design 3D models. Your agent writes CadQuery or build123d Python scripts. agentcad handles execution, STEP export, PNG rendering, mesh export (STL/GLB/OBJ), geometric metrics, validation, diffing, and browser preview. All command output is structured JSON. agentcad is open source under the Apache License 2.0. It runs locally and requires no signup. Quick start Install agentcad, then paste this into Claude Code, Cursor, or any coding agent: Create a Python 3.12 virtual environment, then: pip install agentcad agentcad skill install agentcad --help Read the --help output — it's your operational briefing. Then design me a phone stand: a simple angled cradle that holds a phone at 60 degrees.
