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.

How are those CLIs being installed and run on hosted services? You'll need to sandbox them and have a way to install them automatically which seems difficult. How does the auth flow work? You'd need to invent some convention or write glue for each service. These are far more complicated than just using MCP, regardless of the benefits of the protocol itself.
