Modern developers are searching for practical ways to reduce hallucinations, improve accuracy, and create AI systems they can trust in real-world environments. This book answers that need with a hands-on, engineering-focused approach to Retrieval-Augmented Generation (RAG), the Model Context Protocol (MCP), and LangChain.
You'll learn why context matters, how retrieval pipelines function, and what it takes to integrate embeddings, vector stores, tool calling, agents, and orchestration workflows that perform consistently under real production constraints. Readers benefit from both conceptual clarity and hands-on examples that bring each system to life.
What makes this book stand out?
It focuses on real engineering challenges and provides a structured look at the technologies shaping today's AI systems, including:
Foundations of Context Engineering: Why context quality directly affects LLM accuracy, reliability, and reasoning.
Retrieval-Augmented Generation: How retrieval works, how to improve relevance, and how to reduce hallucinations with solid data pipelines.
Model Context Protocol (MCP): How to design safe tool interactions, build tool servers, and manage deterministic workflows.
LangChain in Practice: Building agents, pipelines, and evaluation workflows that scale.
Production-Focused Patterns: Architecture options, evaluation strategies, failure handling, and observability.
Hands-On Projects: End-to-end examples that bring RAG, MCP, and LangChain together into practical, testable systems.
Readers will find answers to the questions engineers ask every day: How do I build an AI system that stays grounded? What makes retrieval robust? How can tools and models interact without unpredictable behavior? What engineering patterns lead to scalable, testable applications?
If you want to improve your AI systems' accuracy, strengthen your retrieval pipelines, or build applications that behave consistently with real data and tools, this book gives you the guidance to make it happen.
Build smarter. Build reliably. Get the practical reference every AI engineer needs.
