Project Overview: Requirements and Architecture

Welcome to the final hands-on project of this book, where we will consolidate your understanding of Model Context Protocol (MCP) and Agent-to-Agent (A2A) protocols by building a practical, real-world application. This chapter guides you through constructing a hybrid healthcare assistant capable of securely accessing Electronic Health Records (EHR) data and automating patient interactions. By combining MCP for data grounding and A2A for workflow automation, you will create a powerful, interoperable system.

The healthcare domain presents unique challenges, particularly regarding data security, privacy, and complex workflows. EHR systems are often siloed and require strict access controls, making them ideal candidates for MCP's context-aware data retrieval capabilities. Patient interactions, such as scheduling appointments or asking basic queries, can be automated using a network of collaborative A2A agents.
