I'm not super deep into all of this, but I think except latest Claude Code release the mcp is frontloaded into the context. So if you don't need it that often you have to disable and enabled it again when needed.

And I guess you can put some usage examples into the skill file. Which might migate the first --help.

Also I guess with cli it's easy to spin up a sub agent with their own context that just returns the result?
