Build a production-ready multi-agent AI framework from scratch using MCP and A2A to orchestrate powerful agent workflows
Free with your book: DRM-free PDF version + access to Packt's next-gen Reader*
Key Features:
- Build Python-based AI agents without relying on third-party orchestration frameworks
- Design production-ready multi-agent systems using A2A messaging
- Integrate memory and context with MCP to create adaptive and stateful agentic AI frameworks
Book Description:
Frustrated by opaque agent frameworks that hide how things work? This book gives you complete control by guiding you through building a fully functional, extensible agentic AI framework in Python without relying on external orchestration tools.
You'll begin by implementing a simple tool-using agent, and then gradually extend its capabilities with structured tool schemas, user interfaces, and memory via the Model Context Protocol (MCP). From there, you'll build collaborative multi-agent systems powered by Agent-to-Agent (A2A) messaging and deploy them in realistic environments. Along the way, you'll explore secure tool invocation, message routing, observability, and human-in-the-loop workflows.
With annotated code, deep engineering insights, and practical deployment patterns, this hands-on guide equips you to build AI agents that reason, plan, act, and adapt, whether you're shipping production systems or experimenting with cutting-edge LLM-based architectures.
Written by Gigi Sayfan, who builds AI agent infrastructure at Perplexity and is a bestselling author with decades of experience in AI and distributed systems, this book gives you the tools and knowledge to engineer your own advanced agentic systems.
