The MCP Standard

Master the art of building feature-rich Model Context Protocol (MCP) servers in TypeScript, by designing decoupled, scalable, and future-proof AI systems that are not locked into a single model vendor. In the world of AI development mired in a chaotic mess of proprietary, incompatible APIs, the Model Context Protocol is the open standard that will become the universal language for AI tools. This book will be your invaluable companion for understanding this solution. The book takes you on a full, hands-on journey through MCP, looking at it not just as a technical specification but also as a way to help AI-native transformation. It first finds the "why”, the tool's issue — and shows how MCP is the only logical solution. After that, the book goes into deep detail about the protocol's architecture, breaking down the roles of the Host, Client, and Server, and giving you a guide to its main language of Tools, Resources, and Prompts. Using the official TypeScript SDK, you will learn how to build a full-featured MCP server from scratch. You will learn best practices for everything from schema design with Zod to adding advanced features like elicitation and server-side sampling. The book is unique in its holistic approach. It doesn't just tell you how to do something; it also has a whole section on production readiness and security that talks about the MCP security model, threat landscapes, and client-side hardening. This book will give developers, architects, and technical leaders not only the tactical skills they need to succeed in the next wave of software development but also the strategic vision they need to do so. By the end of this book, you will not only have learnt how to use the MCP, but you will have gained a deep understanding of MCP in the context of the larger shift from cloud-native to AI-native. You Will Learn To:

• Master the art of building feature-rich MCP servers in TypeScript, from basic tools to advanced capabilities like elicitation, resource linking, and server-side sampling.
• Understand the complete MCP architecture and protocol specification, enabling you to debug complex interactions and build custom clients or servers.
• Implement a robust, multi-layered security strategy for your MCP deployments, including authentication, authorization, and client-side hardening against common threats.
• Solve the "M x N" integration problem by designing decoupled, scalable, and future-proof AI systems that are not locked into a single model vendor.
• Gain a strategic understanding of MCP's role in the broader AI-native transformation, which empowers you to make informed architectural decisions for your organization.

This Book is For: Software developers, AI engineers, and solutions architects who are creating apps that interface with large language models should read this book.
