What is MCP?

MCP is an open standard by Anthropic that lets AI assistants connect to external tools. Instead of copy-pasting code or switching between apps, your AI talks directly to BuildCAD AI to create, preview, and save CAD designs.
- Open standard, not locked to any single AI provider
- Your AI subscription pays for the tokens, BuildCAD AI is free
- Works in Claude, Cursor, Windsurf, Claude Code, and more
