21st dev Magic MCP Server

What is the 21st.dev MCP Server (Magic Component Platform)?

The Magic Component Platform (MCP) is a powerful AI-driven tool designed to revolutionize UI development. While not a traditional backend server, it acts like a specialized 21st.dev MCP Server within your development environment, focusing specifically on generating UI components. Its core function is to interpret natural language descriptions and instantly create beautiful, modern UI components inspired by the extensive library found at 21st.dev.

This tool integrates seamlessly into popular IDEs, allowing developers to describe the UI they need in plain English and have the corresponding code generated and added to their project almost instantly, significantly streamlining the front-end development workflow.

How to Use This UI Generation MCP Tool

Using the Magic Component Platform is designed to be intuitive and integrated directly into your coding process:

1. Describe Your Need: Within the chat interface of a supported AI Agent in your IDE (like Cursor or Windsurf), use a simple command (e.g., '/ui') followed by a description of the UI component you want. For example, "create a modern login form".
2. Engage Magic: Your IDE may prompt you to confirm using the Magic Component Platform tool.
3. Instant Creation: The tool processes your request and instantly generates a polished UI component. The style and structure are inspired by the modern components available from 21st.dev.
4. Seamless Integration: The newly created component code is automatically added to your current project files, ready for you to use and customize further.

User Case Example

Imagine you're building a new feature and need a user profile card displayed.

• Scenario: You need a visually appealing card component quickly.
• Action: In your AI-integrated IDE, you type: '/ui create a user profile card showing avatar, name, and email'.
• Behind the Scenes: The Magic Component Platform (acting as the 21st.dev MCP Server for UI tasks) interprets this, generates the code for a modern profile card based on 21st.dev styles, and inserts it into your project.
• Result: You get a ready-to-use, well-styled UI component in seconds without writing the boilerplate code manually.
