Building Production AI Agents for the Web: Design and orchestrate autonomous agents with MCP, Multi-Agent Patterns, and Harness Engineering

Design, orchestrate, and deploy scalable AI agents with real-world patterns, multi-agent systems, and evaluation frameworks. Key Features Filled with real-world agentic web application examples using LLMs, RAG, and tool calling Design and implement AI assistants with reasoning patterns like ReAct Architect scalable agent systems with planning, orchestration, and autonomy Book Description AI is no longer just about generating text. It’s about building autonomous, goal-driven systems that can reason, act, and collaborate. Hands-On AI Agents for the Web is your practical guide to designing and deploying agentic web applications powered by Large Language Models (LLMs). Starting with the fundamentals of agentic thinking and responsible AI, this book walks you through integrating LLMs into real-world web apps. You’ll progressively enhance your systems with tool calling, Retrieval-Augmented Generation (RAG), and advanced reasoning patterns like ReAct, before moving into the design of fully autonomous agents. As you advance, you’ll explore agent architectures, planning systems, orchestration, and multi-agent collaboration, learning how modern frameworks and protocols like Model Context Protocol (MCP) enable scalable, interoperable AI systems. The book emphasizes hands-on learning, with practical examples that demonstrate how to build AI assistants, coordinate multiple agents, and apply proven design patterns, while avoiding common pitfalls. By the end, you’ll have the skills to build production-ready, intelligent web experiences powered by autonomous agents. What you will learn Understand agentic thinking and responsible AI principles Integrate LLMs into web applications and build prompt-driven systems Enhance LLM capabilities with tool calling and external integrations Implement RAG pipelines for context-aware, accurate AI responses Implement planning systems for goal-driven agents Orchestrate autonomous agents and manage workflows at scale Identify agent design patterns and avoid common anti-patterns Test, evaluate, and improve agent performance using evaluation frameworks Who this book is for This book is for full-stack developers, software architects, and AI practitioners looking to build intelligent, agent-driven web applications. It’s also valuable for tech leads and product managers working on AI-powered products. If you have a basic understanding of web development and want to move beyond simple AI integrations into autonomous, production-ready agent systems, this book will give you the frameworks, tools, and hands-on experience to get there.
