Building an AI chatbot is easy. Building an AI application that can use tools, remember context, retrieve reliable information, follow workflows, recover from failures, and operate safely in production is much harder.
Building AI Agents with Mastra and TypeScript shows you how to make that transition step by step.
You do not need previous experience with Mastra, autonomous agents, RAG systems, or multi-agent architectures. If you have basic familiarity with TypeScript or JavaScript and Node.js, this practical guide will help you build confidence as each concept is introduced gradually and applied to a growing real-world project.
Instead of overwhelming you with theory or giant code dumps, the book breaks production AI engineering into manageable stages. You will build agents, connect safe tools, add structured outputs and persistent memory, create production-ready RAG pipelines, design durable workflows with human approval, integrate MCP services, coordinate specialized agents, evaluate behavior, strengthen security, and prepare your application for deployment and scale.
Mistakes, failed tool calls, weak retrieval results, and unexpected model outputs are treated as part of the learning process. Each chapter helps you understand what went wrong, improve the system, and move forward with greater confidence.
