Middleware in Microsoft Agent Framework

This article explores middleware within the Microsoft Agent Framework, focusing on its role in managing token usage in multi-agent applications. It defines middleware as an intermediary layer that processes requests and responses, enabling developers to intercept, inspect, and modify data flow. Key benefits include cost control by limiting token consumption to prevent unexpected expenses, enhanced security through request validation, improved performance by optimizing data flow, and custom logic implementation for tailored interactions. The article also introduces types of middleware, such as Agent Run Middleware, and provides guidance on effective implementation.
