All true except that CLI tools are composable and don't pollute your context when run via a script. The missing link for MCP would be a CLI utility to invoke it.
replyHow does the agent know what clis/tools it has available? If there's an `mcpcli --help` that dumps the tool calls, we've just moved the problem.
replyThe composition argument is compelling though. Instead of clis though, what if the agent could write code where the tools are made available as functions?
tools.get_foo(tools.get_bar())
