**Test Mode** lets you test your AI agent before making it available to all customers. It’s useful for reviewing how well the agent understands your business queries and ensuring the tone and responses are accurate and appropriate.

#### How to Set Up the Test Mode in Mercuri CX ?

1. While creating a new AI agent, toggle the switch to **Test Mode**.
2. Choose your preferred communication channel —  **WhatsApp** or **SMS**. In the **Available Numbers** section, click **+ Add** next to the number associated with your business.
3. Enter a **Test Phone Number** , this is the number from which you’ll test the agent.
4. Only messages from this test number will receive responses from the AI, allowing for safe and private testing.
