🎯 What Can You Do?

💬 Natural Language → SQL

You: "Show me total revenue by product category for the last 30 days"
AI: Uses ai_sql_generate → Runs query → Returns formatted results

📊 Instant Dashboard Creation

You: "Create an executive dashboard for our e-commerce sales"
AI: Uses mb_dashboard_template_executive → Creates fully configured dashboard

🔍 Deep Database Exploration

You: "What tables are related to 'orders' and show their relationships"
AI: Uses db_relationships_detect → Returns complete ER diagram info

🛡️ Enterprise-Grade Security

You: "DROP TABLE users" 
AI: 🔒 Blocked - Read-only mode active
