# MCP Chain

> Use this tool when you need to transform requests and responses in MCP servers or add cross-cutting concerns like authentication and logging to existing infrastructure. The MCP Chain framework enables the creation of transparent proxies, allowing for flexible and composable middleware solutions. It accepts MCP server requests and responses as inputs and outputs modified requests and responses, making it ideal for use cases requiring AI-driven orchestration or enhanced security and logging capabilities.
