请问HN：使用MCP相比于函数字典有什么好处？
我对MCP的热度感到非常困惑。我查看了他们的文档以了解快速入门，发现这似乎比简单使用字典要花更多的工作和代码。我觉得我一定遗漏了什么。能否请有人详细解释一下它的用处是什么？

I'm really confused with the MCP hype. I looked through their docs for quick start and it looks like more work and code than doing it simply with a dictionary. I feel I must be missing something here. Could someone please elaborate on why it is useful?
