MCP Integration

To use MCP with external AI assistants:

Claude Desktop Setup

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "featuredapp": {
      "command": "node",
      "args": ["/path/to/your/project/mcp-server/dist/index.js"]
    }
  }
}

Example AI Interactions

User: "How does Airbnb structure their design system?"
AI: Uses MCP get_case_study("airbnb") → Provides comprehensive Airbnb design system analysis

User: "Show me an autocomplete component implementation"
AI: Uses MCP get_feature_component("autocomplete") → Returns complete working code

User: "What are the key concepts in frontend architecture?"
AI: Uses MCP get_learning_concepts() → Lists and explains core concepts
