AI Agents and Applications

AI Agents and Applications provides a practical, step-by-step approach to building LLM-powered applications using state of the art tools like LangChain, LangGraph, and MCP. You’ll quickly master prompt engineering techniques for automated systems and advanced RAG techniques. Then, you’ll move into structured agentic workflows with LangGraph and flexible, tool-based agent architectures. The book guides you through creating single and multi-agent systems, debugging and optimizing agent performance, and integrating external tools using the new Model Context Protocol (MCP). With visual explanations and real code throughout, this book delivers everything you need to go from your product ideas to production-ready AI solutions.
