Deploying and Publishing

I was recently putting the finishing touches on an MCP server I had been building for a side project. Everything worked beautifully on my machine. The tools responded, the resources loaded, the prompts rendered perfectly. Then a colleague asked me, "Hey, can I try that?" And just like that, I was staring at the age-old problem every developer knows too well: it works on my machine, but how do I get it to work on yours?
