Designing Agentic AI Systems with MCP and A2A: Persistent Context, Agent Collaboration, and Scalable Multi-Agent Systems (Agentic AI Systems in Practice Book 1)

Designing Agentic AI Systems with MCP and A2A is a comprehensive, hands-on guide to building modern AI agents that can remember context, communicate intelligently, and collaborate at scale using the Model Context Protocol (MCP) and Agent-to-Agent (A2A) communication standards.As AI systems move beyond single-prompt interactions toward long-running, autonomous workflows, developers face new challenges: how to persist memory across sessions, coordinate multiple specialized agents, manage failures, and scale reliably in production. This book addresses those challenges directly by teaching you how to design and implement agentic AI systems that reason, plan, and act together without reinventing foundational infrastructure.Starting from first principles, the book explains how MCP enables durable, versioned context storage for AI agents, allowing them to retain conversation history, user preferences, and world state across restarts and deployments. You’ll then explore how A2A communication allows agents to delegate tasks, exchange progress updates, handle errors, and coordinate complex workflows through structured peer-to-peer messaging.Rather than relying on abstract theory, this book emphasizes practical system design and real implementation patterns. Using production-ready examples in Python and JavaScript, you’ll learn how to set up MCP servers and clients, implement A2A messaging flows, and integrate these protocols with popular AI frameworks and orchestration tools. Advanced chapters cover secure authentication, streaming large context payloads, sharding and compression strategies, and multi-agent planning across distributed environments.The book also includes real-world case studies drawn from customer support automation, enterprise workflow orchestration, and autonomous systems, highlighting common pitfalls and proven architectural patterns. By the end, you’ll be equipped to design AI agent ecosystems that are not only intelligent, but robust, maintainable, and scalable.Whether you are an AI engineer, backend developer, systems architect, or technical founder, Designing Agentic AI Systems with MCP and A2A provides the knowledge and practical skills needed to build collaborative, context-aware AI systems ready for real-world deployment.What You Will LearnHow MCP enables persistent, versioned context for long-running AI agentsHow A2A communication structures agent collaboration and task delegationDesign patterns for scalable, multi-agent AI architecturesSecure authentication and authorization for agent communicationStreaming, sharding, and compression techniques for large-scale deploymentsReal-world lessons from production AI agent systems.
