AI agent technology is changing fast! This totally revised Second Edition of AI Agents in Action by Micheal Lanham guides you through the latest breakthroughs in large language model (LLM)-powered autonomy, from the Model Context Protocol (MCP) to advanced multi-agent collaboration and deployment.
Whether you’re upgrading your customer service systems, creating a research assistant, or deploying a fleet of internal agents to automate enterprise tasks, this hands-on guide will help you build trustworthy agents that can handle high-stakes tasks. Extensively revised, this second edition contains new chapters on MCP, containerized deployment, and voice agent orchestration, along with refreshed coverage of LangChain, Prompt Flow, CrewAI, and more.
In AI Agents in Action, Second Edition you’ll learn how to:
• Design and deploy production-grade autonomous agents
• Use MCP, the OpenAI Assistants API, and tools to build adaptable systems
• Take advantage of retrieval-augmented memory, feedback loops, and self-improving behaviors
• Orchestrate voice and vision-enabled agents
• Containerize and scale your agents
