It's like v0, but in your Cursor / Claude Code / Windsurf: search 10,000+ React/Tailwind components, generate new UI with AI, and publish your own — right from your editor. Magic MCP is now the 21st MCP; this package keeps old configs working. Setup: 21st.dev/mcp

1安装 / 启动命令npm / npx

npx -y @21st-dev/magic

2客户端配置Claude Desktop / Cursor

{
  "mcpServers": {
    "21st-dev-magic-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@21st-dev/magic"
      ]
    }
  }
}

整段粘进 claude_desktop_config.json 的 mcpServers 里（Cursor 用 ~/.cursor/mcp.json），保存后重启客户端。

安装方式来源：npm registry match (has bin)，沙箱实测未通过。
