alt Hacker News"intentionally provocative"
I would almost use the words "intentionally uninformed" instead.
There are huge holes in the article (as pointed out by many comments here), and I have to wonder if you genuinely don't have enough experience with MCP to bring them up, or you intentionally omitted them to make the arguments for CLI.
I get it. This is coming from a place where I see MCP's being adopted, where CLI is (in my opinion) better. Particularly where you're already in a CLI environment, and tool composition is necessary. I'm sure there's plenty of folks that aren't operating in that environment.
