Yesterday I accidentally stumbled on a place where I could really appreciate MCP's.

I wanted to connect my Claude account to my Notion account. Apparently all you need to do is just submit the notion MCP and log in. That's it! And I was able to interact with my Notion data from my Claude account!

Imagine how hard this would be with skills? It is literally impossible because with skills, you may need to install some local CLI which Claude honestly should not allow.

If not CLI, you need to interact with their API which again can't happen because you can't authenticate easily.

MCP's fill this narrow gap in my opinion - where you don't own the runtime and you want to connect to other tools like plugins.
