🚀 Getting Started

Prerequisites

Node.js (Latest LTS version recommended)
One of the supported IDEs: Cursor, Windsurf, VSCode (with Cline extension)

Installation

Generate API Key
- Visit 21st.dev Magic Console
- Generate a new API key
Choose Installation Method

Method 1: CLI Installation (Recommended)

One command to install and configure MCP for your IDE:

npx @21st-dev/cli@latest install <client> --api-key <key>

Supported clients: cursor, windsurf, cline, claude

Method 2: Manual Configuration

Add this to your IDE's MCP config file:

{
  "mcpServers": {
    "@21st-dev/magic": {
      "command": "npx",
      "args": ["-y", "@21st-dev/magic@latest", "API_KEY=\"your-api-key\""]
    }
  }
}

Config file locations:

Cursor: ~/.cursor/mcp.json
Windsurf: ~/.codeium/windsurf/mcp_config.json
Cline: ~/.cline/mcp_config.json
Claude: ~/.claude/mcp_config.json

Method 3: VS Code Installation

Manual VS Code Setup

Add the following JSON block to your User Settings (JSON) file in VS Code (Ctrl + Shift + P → Preferences: Open User Settings (JSON)):

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "apiKey",
        "description": "21st.dev Magic API Key",
        "password": true
      }
    ],
    "servers": {
      "@21st-dev/magic": {
        "command": "npx",
        "args": ["-y", "@21st-dev/magic@latest"],
        "env": {
          "API_KEY": "${input:apiKey}"
        }
      }
    }
  }
}

Optionally, add it to .vscode/mcp.json in your workspace:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "apiKey",
      "description": "21st.dev Magic API Key",
      "password": true
    }
  ],
  "servers": {
    "@21st-dev/magic": {
      "command": "npx",
      "args": ["-y", "@21st-dev/magic@latest"],
      "env": {
        "API_KEY": "${input:apiKey}"
      }
    }
  }
}

❓ FAQ

How does Magic AI Agent handle my codebase?

Magic AI Agent only writes or modifies files related to the components it generates. It follows your project's code style and structure, integrating seamlessly with your existing codebase without affecting other parts of your application.

Can I customize the generated components?

Yes! All generated components are fully editable and come with well-structured code. You can modify styling, functionality, and behavior like any other React component.

What happens if I run out of generations?

If you exceed your monthly generation limit, you'll be prompted to upgrade your plan to continue generating components. Existing components remain fully functional.

How soon do new components get added to 21st.dev's library?

Authors can publish components to 21st.dev anytime, giving Magic Agent immediate access to new components and design patterns from the community.

Is there a limit to component complexity?

Magic AI Agent can handle components from simple buttons to complex interactive forms. For best results, break down very complex UIs into smaller, manageable components.
