   curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
   

2. Login to Azure:

   az login
   

3. That's it! Your AI assistant can now connect to your Azure Data Explorer clusters.

Test It Works

Ask your AI assistant:

"Connect to my Azure Data Explorer cluster at https://your-cluster.kusto.windows.net and show me the available tables"

You should see your AI successfully connect and list your database tables.

💡 Pro tip: Start by asking your AI to "show me the tables in my database" to explore what data you have available, then ask natural language questions about specific tables.
