The user, having built MCP servers in production, notes that the real complexity lies beyond the protocol itself. They identify a need for common production features such as authentication middleware, rate limiting, structured logging, proper error codes, and Server-Sent Events (SSE) transport for sharing tools among teams. These are often overlooked in tutorials, making it difficult to transition from demo to production.
Clean explanation. What I've found building MCP servers in production: the real complexity isn't the protocol — it's everything around it. You need auth middleware, rate limiting, structured logging, proper error codes. And if you want teams to share tools, you need SSE transport alongside stdio. Most tutorials skip all of this which is why so many people get stuck going from demo to production.
