VantaUI for AI agents

VantaUI is a React component and block library for AI-assisted frontend work. It ships copy-paste components, interface blocks, registry metadata, and an MCP server.

Give your coding agent the catalog and a one-line install. It can find the right piece, read how it works, and add it without opening every page.

Add --scope project to share the server with your team through .mcp.json.
