It is a CAD toolbox that an AI/LLM app can use through MCP. With an LLM app such as Claude, Cursor, VS Code, Continue, Cline, or Codex CLI, build123d-mcp lets the assistant create build123d CAD models, render previews, measure geometry, fix mistakes, and export files such as STEP, STL, SVG, and DXF. Instead of writing a whole CAD script blindly, the assistant can build a part in small steps and check the result as it goes. On the public CADGenBench leaderboard in June 2026, using build123d-mcp raised the same model's score from 0.360 to 0.457 and CAD validity from 88% to 100%. Pick Your Setup Most users should start with the local MCP server setup: - You use Claude, Cursor, VS Code, Continue, Cline, or Codex CLI on your own machine. - Your AI app starts build123d-mcp as a local subprocess. - You do not need to clone this repository. Use GitHub Codespaces instead if you want a browser-only trial or a ready-made development workspace with Copilot Chat, Python, uv, and the CAD dependencies already installed. Use HTTP mode only for advanced deployments where you are hosting the MCP server yourself. Quick Start You need: - uv - An AI/LLM app that supports MCP, such as Claude Code, Claude Desktop, Cursor, VS Code, Continue, Cline, or Codex CLI No repository clone is needed for normal use. First check that the package can start: Then add the same command to your AI app's MCP config.
