Enterprise Integration Patterns

So far we have been building fun pizza servers, but at some point, your boss walks in and asks: "Can this thing actually talk to our database? And, you know, not let the entire internet in?" Fair questions. I was recently putting the finishing touches on a proof-of-concept MCP server for a side project when it hit me: everything I had built worked great on my laptop, but it would last about five minutes in a real production environment. No auth, no error handling, no observability. Not great for maintainability.
