How to Set Up and Use Magic Component Platform
Magic Component Platform (MCP) by 21st.dev is an AI-powered MCP server that generates polished, production-ready UI components from natural language descriptions directly inside Cursor, Windsurf, VSCode, and Cline. When you type /ui followed by a component description in your AI coding agent, Magic fetches matching components from 21st.dev's curated library — including SVGL brand logos and assets — and inserts fully typed TypeScript code into your project. It shortens the design-to-code loop from minutes to seconds by eliminating the need to browse component libraries, copy boilerplate, or manually adapt styling.
Prerequisites
- Node.js 18+ and npx available in your terminal
- A 21st.dev API key — create a free account and generate a key at 21st.dev/magic/console
- Cursor, Windsurf, VSCode with Cline, or Claude Desktop as your MCP client
- An existing project with a supported front-end stack (React, TypeScript recommended)
Get your 21st.dev Magic API key
Sign up at 21st.dev and navigate to the Magic Console at 21st.dev/magic/console. Click 'Generate API Key' and copy the key — you will need it in the next step.
Install via the 21st-dev CLI (quickest method)
Run the CLI installer, specifying your target MCP client and your API key. Replace <client> with cursor, windsurf, cline, or claude.
npx @21st-dev/cli@latest install <client> --api-key <your-api-key>Or configure manually in your MCP client config
Add the Magic MCP server directly to your claude_desktop_config.json or equivalent. Replace 'your-api-key' with the key from 21st.dev.
{
"mcpServers": {
"@21st-dev/magic": {
"command": "npx",
"args": ["-y", "@21st-dev/magic@latest"],
"env": {
"API_KEY": "your-api-key"
}
}
}
}Restart your MCP client
Restart Cursor, Claude Desktop, or VSCode to load the new MCP server. The Magic tools will appear in your agent's tool list.
Generate your first component
In your AI agent's chat, type /ui followed by a description of the component you need. The agent will call Magic and insert the generated component code into your project.
Magic Component Platform Examples
Client configuration
Full config block for Claude Desktop at ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows).

"env": {
"API_KEY": "your-21st-dev-api-key"
}
}
}
}Prompts to try
Use /ui followed by a description in your AI coding agent to generate components. These examples show the kinds of components Magic handles well.
- "/ui create a responsive navigation bar with a logo on the left, links in the center, and a sign-in button on the right"
- "/ui build a pricing table with three tiers: Free, Pro, and Enterprise, with a monthly/annual toggle"
- "/ui design a dark-mode dashboard card showing a metric with a trend sparkline"
- "/ui create a file upload dropzone with drag-and-drop support and a file list preview"
- "/ui build a multi-step form wizard with progress indicator for user onboarding"Troubleshooting Magic Component Platform
API_KEY is rejected with a 401 Unauthorized error
Verify the key was copied in full from 21st.dev/magic/console with no trailing whitespace. API keys are account-specific — confirm you are logged in to the correct 21st.dev account. Regenerate the key if needed.
/ui command is not recognized by the AI agent
The /ui trigger requires the Magic MCP server to be running and connected. Restart your MCP client after adding the config and verify the server appears in the connected tools list. Some clients require the server to be explicitly enabled per-project.
Generated component uses a styling library not present in the project
Magic infers the styling approach from context but may default to Tailwind CSS. If your project uses a different system, specify it explicitly in the prompt: '/ui create a navigation bar using CSS Modules' or '/ui ... using styled-components'.
