Some folks like having an MCP package. I agree that gives you a bit more control. But I live dangerously and run emacs in daemon mode and tell claude to just run emacsclient to execute elisp as needed. It works amazingly well. Claude has full visibility into my editor and together we can pretty much do anything.
In fact, I increasingly think of emacs as just a live lisp machine. It's a surface that I and the agents can interact against. It acts as a document store, database, control surface, etc.
