21st.dev Magic

The 21st.dev Magic MCP server is designed to bridge the gap between natural‑language design intent and production‑ready UI code. By exposing a single command, it lets developers describe the appearance and behavior of components—such as “a responsive navigation bar with a dark theme”—and instantly receive a fully‑typed, ready‑to‑use component that adheres to the modern design system of 21st.dev. This eliminates the need for manual scaffolding, style duplication, and boilerplate, allowing designers and engineers to iterate rapidly while maintaining consistency across projects.

At its core, the server offers an AI‑powered code generation engine that understands both visual and functional requirements. It leverages a curated library of pre‑built, customizable components, ensuring that every generated piece can be tweaked or extended without sacrificing type safety. The integration with TypeScript guarantees that the resulting code fits seamlessly into existing type‑checked workflows, reducing runtime errors and improving developer confidence.

Magic’s real‑time preview feature is a standout advantage: as soon as the component is generated, it appears instantly in the connected IDE’s preview pane. This immediate feedback loop lets developers validate design decisions on the fly, adjust properties, and see the impact without leaving their editor. The server also supports multiple IDEs—Cursor, Windsurf, VS Code (with or without the Cline extension)—providing flexibility for teams that use different tooling ecosystems.

Typical use cases include rapid prototyping, onboarding new team members with a consistent component library, and automating repetitive UI tasks such as form layouts or navigation bars. Because the server can be invoked directly from an AI assistant’s chat interface, it integrates naturally into conversational development workflows, enabling a “chat‑to‑code” experience that feels intuitive and productive. Developers can thus focus on higher‑level architecture while Magic handles the repetitive, stylistic details.

In summary, 21st.dev Magic delivers a developer‑centric solution that turns natural language into high‑quality, type‑safe UI components with instant previews. Its multi‑IDE support, integration with a modern component library, and seamless AI workflow integration make it an indispensable tool for teams looking to accelerate UI development without compromising quality or consistency.
