What is agentcad?
Agentcad is an open-source CAD tool for AI agents, providing an MCP server and CLI that allow coding agents to generate, validate, and export 3D models through Python scripts, with immediate feedback and geometry validation.
How to use agentcad?
- 1Create a Python virtual environment with Python 3.12.
- 2Install agentcad using pip: pip install 'agentcad[mcp]'
- 3Run agentcad skill install to set up the agent skill.
- 4Integrate with your coding agent by adding the MCP server configuration.
- 5Provide a prompt describing the desired CAD object.
- 6The agent will generate the Python script, agentcad executes it and returns metrics and previews.
- 7Iterate on the design using feedback until the geometry is valid.
agentcad Key Features
- Execute Python CAD scripts to generate versioned STEP files and geometric metrics
- Render PNG previews from multiple angles for visual verification
- Export models to STL, GLB, OBJ, and STEP formats
- Pre-execution geometry validation in under 100ms
- Topology inspection for debugging geometry issues
- Version diffing to track design iteration changes
