MCP Engineering Handbook: A software engineer's guide to building real-world AI integrations using the Model Context Protocol

Understand how modern Model Context Protocol works under the stateless protocol and apply it confidently to real-world AI systems, from integration design to production operations. Purchase of the print or Kindle book includes a free PDF eBook Key Features Build production-ready MCP clients and servers in C#, Python, and TypeScript Design for modern stateless MCP with security, resilience, and scale Use MCP’s full capability set to create composable agentic architectures Book DescriptionModel Context Protocol is changing quickly, and much of the available guidance still reflects an earlier, session-based architecture. MCP Engineering Handbook focuses on the current stateless, per-request protocol and shows how to build integrations that remain robust as the ecosystem evolves. You’ll examine MCP’s architecture, transports, JSON-RPC, capability declarations, and model integration, then develop tools, resources, prompts, elicitation, extensions, and MCP Apps. Using C#, Python, and TypeScript, you’ll design purpose-driven MCP servers and resilient clients, work with explicit state handles, and apply patterns for progressive disclosure and recursive or symmetric composition. The book then moves into authentication and authorization, evaluation, observability, deployment, scaling, gateways, supply-chain governance, and host-side security. It also places MCP within the wider agentic AI stack, helping you decide where the protocol fits and where its responsibilities end. By the end, you’ll be able to design, secure, evaluate, deploy, and operate MCP-based systems from focused integrations to enterprise-scale agentic architectures. What you will learn Design MCP tools for model comprehension and reliable invocation Build stateless MCP servers with explicit state-handling patterns Implement resilient MCP clients with strong trust boundaries Integrate resources, prompts, elicitation, extensions, and MCP Apps Apply OAuth 2.1 and enterprise authorization patterns to MCP Evaluate MCP systems and monitor model-generated traffic Scale MCP deployments with gateways, proxies, and stateless routing Architect composable agentic AI systems and define MCP's role in the wider stack Who this book is forThis book is for software engineers and architects building AI-powered applications or designing systems around Model Context Protocol. It suits readers who want to move beyond basic MCP usage and make sound decisions about architecture, security, deployment, and operations. Basic familiarity with LLM APIs or SDKs and experience with C#, Python, or TypeScript will help.
