Lately I found MCP to be much more than a coding tool. For example, I implemented it in my more complex macOS apps [0] like rcmd, Clop, Lunar, so they can be configured by natural language.

So even with a local Qwen and Pi you can now say things like:

    Set up Clop to optimise any PNG that I drop in my website assets folder and convert to a webp with the same name near it

    Get Crank to start Time Machine backups immediately when I connect my HDD and notify me when the backup is done.

    I want to be able to hold rcmd and fuzzy search and focus cmux agent panes

BetterTouchTool has a great MCP which can create native SwiftUI views and bind them to hotkeys, trackpad gestures etc. It can leverage its immense macOS automation tools and private APIs to let agents do Computer Use.

You would need a much more capable coding model to code those tools from scratch and get the same fail-safe logic that the apps have honed over the years.
