Integrating Azure Functions with AI Foundry Agent service enables you to build intelligent, event-driven applications that are scalable, secure, and cost-efficient. Azure Functions act as custom tools that AI agents can call to execute business logic, access secure systems, or process data dynamically in response to events like HTTP requests or queue messages. This integration allows for modular AI workflows, where agents can reason through tasks and trigger specific functions as needed—ideal for scenarios like customer support, document processing, or automated insights—without the need to manage infrastructure.
