MCP seems like what you'd do when you want to encapsulate and share a skill+script in a standard way.
personally if i have the need to move a skill/script, etc. to another one of my machines, i'll make a git repo for them (if they aren't already on git)
You can share a skill by copy pasting the text file to someone in slack.
Its not that hard.
