alt Hacker Newsno, it's all about auth. MCP lets less-technical people plug their existing tools into agents. They can click through the auth flow in about 10 seconds and everything just works. They cannot run CLIs because they're not running anything locally, they're just using some web app. The creator of the app just needed to support MCP and they got connectivity with just about everything else that supports MCP.
Write better CLIs for the agents of the less-technical people. The MCPs you're talking about don't exist yet either. This doesn't seem complicated; MCP seems like a real dead end.
