Haha. Nobody ever cared that some humans preferred to use services via a CLI versus GUI. But now that "AI" needs it, CLI programs and APIs get released left and right :D
With AI, two things have changed: (1) the cost of building a CLI on top of a documented API has dropped a lot, and (2) there’s a belief that “designed for agents” CLIs will enable new kinds of usage that weren’t practical before and that will move the needle on the bottom line.
And now, since bloated agent harnesses like Claude Code are the hot thing, AI promoters are calling MCP obsolete! (No need for HN's summer 2025 fad. Just write CLI tools!)
