Is there any redeeming quality of MCP vs a skill with CLI tool? Right now it looks like the latter is a clear winner. Maybe MCP can help segregate auto-approve

  MCP defines a consistent authentication protocol. This is the real issue with CLIs, each CLI can (and will) have a different way of handling authentication (env variables, config set, JSON, yml, etc). But tbh there's no reason agents can't abstract this out. As long as a CLI has a --help or similar (which 99% do) with a description of how to login, then it can figure it out for you. This does take context and tool calls though so not hugely efficient.

    That's fair. I just really don't like the way MCP gives the tool author control of my context. It's worth setting up some env vars and config files to avoid them.
