Most MCP tutorials use Python. That's fine for prototypes. But when you need a server that handles thousands of concurrent connections on 128 MB of RAM, starts in 50ms, and deploys as a single binary — you need Go. I spent the last few months building MCP servers in Go for production systems. Eight different servers, 4,000+ lines of production code, handling real workloads across project management, browser automation, knowledge bases, and multi-agent orchestration. Then I realized: there is no book on this. Not one. The MCP docs cover the protocol. There are Python quickstarts. TypeScript examples. But nothing that shows you how to build a production Go MCP server with authentication, database integration, deployment, and billing. So I wrote one. Why Go for MCP Servers?
