21st.dev Magic is an MCP server that generates modern, production-ready UI components from natural language descriptions. It accesses 21st.dev's curated component library and outputs React + TypeScript + Tailwind CSS code directly into your project.
Describe the component you need naturally. The MCP server tools will be available when the server is running. Common invocation patterns:
"Generate a hero section with animated text reveal and gradient background"
"Create a responsive navigation bar with transparent-to-solid scroll effect"
"Build a pricing card grid with hover animations"
"Design a testimonial carousel with star ratings"
#C9A035 as accent, #0D1B3E for text"Generated components land as .tsx files. To integrate:
