 ### 2. Deploy an agent in the Microsoft Foundry Agent Service
 
 To test this scenario, you'll be deploying an AI agent included in this repository. The agent uses a GPT model combined with a Bing search for grounding data. Deploying an AI agent requires data plane access to Foundry. In this architecture, a network perimeter is established, and you must interact with the Foundry portal and its resources from within the network.
