Installieren

Wählen Sie Ihren Client

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

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

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

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

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

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

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

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

In context_servers hinzufügen. Zed lädt beim Speichern neu.

claude mcp add magic-mcp -- npx -y @21st-dev/magic@latest

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: 21st.dev Magic MCP

Generate a polished landing-page hero in under a minute

👤 Frontend engineers shipping fast ⏱ ~15 min intermediate

Wann einsetzen: You need a hero section right now and don't want to start from a blank file.

Voraussetzungen

Server/skill installed and authenticated — See repo README

Ablauf

Search for inspiration

Search 21st for hero sections that mix gradient + product screenshot.✓ Kopiert

→ 5–10 starter components
Generate the final one

Create a Hero component: dark gradient bg, headline 'Ship faster.' subhead 'AI for serious teams.' a primary CTA + secondary CTA, social proof row.✓ Kopiert

→ A complete tsx file using shadcn primitives

Ergebnis: A real production-shape component in one prompt.

Fallstricke

Generated components assume shadcn primitives are installed — Generated components assume shadcn primitives are installed — run npx shadcn add button card first.
