npm run setup-db

Step 5: Start Authentication Server

# In a separate terminal
npm run auth-server

Visit http://localhost:3000 to login and get your authentication token.

Step 6: Start MCP Server

# In another terminal
npm run dev

Step 7: Configure Cursor

Add to your Cursor MCP configuration (~/.cursor/mcp.json):

{
  "mcpServers": {
    "my-blog": {
      "command": "node",
      "args": ["dist/universal-server.js"],
      "cwd": "/path/to/your/my-blog",
      "env": {
        "DATABASE_URL": "your_database_url",
        "KINDE_ISSUER_URL": "your_kinde_issuer_url",
        "KINDE_CLIENT_ID": "your_kinde_client_id",
        "KINDE_CLIENT_SECRET": "your_kinde_client_secret",
        "JWT_SECRET": "your_jwt_secret"
      }
    }
  }
}
