About the Book

This book takes you from zero MCP knowledge to advanced practitioner level. You will learn the protocol internals, build servers in Python, TypeScript, Go, Rust, and Java, harden them for production with security and observability, deploy them at scale using Docker and Kubernetes, and integrate them into real-world AI systems. Every chapter includes complete, runnable code that you can adapt directly into your own projects. Whether you are building a database assistant, a file management server, an enterprise knowledge system, or an AI agent tool hub, this book gives you the patterns, practices, and production experience to do it right.

Steve Publications

Steve is a technology professional with more than 20 years of experience spanning software development, server infrastructure, cybersecurity, vulnerability research and reverse engineering. His work focuses on understanding complex systems, uncovering security weaknesses and developing practical solutions that make technology more secure, reliable and effective.

Through Steve Publications, he collaborates with experienced researchers, engineers and industry experts to create practical, technically rigorous books on various topics not limited to self-improvement, software development, cybersecurity, cloud computing, DevOps, artificial intelligence and enterprise technologies. His mission is to make complex technical subjects accessible through clear explanations, real-world examples and hands-on exercises that help IT professionals, students and technology enthusiasts build valuable, practical skills.

Steve Publications embraces AI as a supporting tool for translation, proofreading and editorial refinement, not as a substitute for original research, technical expertise, or hands-on experience. Some contributors choose to publish under pseudonyms to protect their privacy or maintain professional boundaries.

Behind every book is a commitment to technical accuracy, practical relevance and continuous improvement. Our publications are written, reviewed and maintained by experienced professionals, with support from a private community of more than 420 engineers and researchers. Rather than prioritizing volume or mass-produced AI-generated content, we focus on delivering reliable, useful resources that readers can apply in real-world environments.

We also welcome experienced professionals who want to share their knowledge by writing or reviewing books, particularly in specialized and emerging technology fields. If you have expertise to contribute, we invite you to get in touch and explore opportunities to collaborate.
