About 21st-dev/Magic-MCP

21st-dev/Magic-MCP is an open-source, AI-powered MCP server that enables developers to generate polished UI components directly within their IDE using natural language prompts. Inspired by the component library of 21st.dev, the tool integrates seamlessly with Cursor, Windsurf, VSCode, and Cline (Beta). Developers describe the desired component via a /ui command, and Magic instantly builds, previews, and adds the code to the project. It features full TypeScript support, access to a library of pre‑built customizable components, real‑time preview, and SVGL integration for professional brand assets. Installation is streamlined via CLI, manual MCP configuration, or one‑click VS Code setup, requiring an API key from the 21st.dev Magic Console.
