The Definitive Guide to Building Model Context Protocol (MCP) Servers
A practical, operator-first book for engineers, consultants, and technical leaders building MCP servers that need to hold up in real systems.
Architecture and decision-making before you build
Core implementation patterns for tools, resources, and remote servers
Security, OAuth, deployment, observability, and operations
Concrete guidance for builders shipping MCP in production
Why this book exists
Most MCP material stops at quick starts, thin examples, or protocol summaries. This book is aimed at the harder part: making good decisions about what to expose, how to secure it, how to keep it operable, and how to avoid building a bad MCP server in the first place.
If you're a product-minded engineer, consultant, or operator trying to connect models to real systems without making a mess, this is for you.
