What can the MCP actually do?

Four things. It can search and pull sections — your AI finds one in the BYQ library and fetches a full integration prompt: a React and Tailwind reference build, the complete design spec, setup notes, and instructions to adapt it to your project. It can search and add gems, the small interaction effects like magnetic buttons, marquees and scroll reveals that you drop onto something already built. It can search and pull wireframes, unstyled layout structures. And it can search and apply design systems as DESIGN.md, tokens.json or CSS to style what it builds. You describe what you want in plain language and your AI handles the rest.
