Plonk MCP server

Plonk is a Mac app that puts a bunch of small desktop tools behind one menu bar icon. It can move windows around, save your desk layouts, take screenshots, read text off the screen, and keep your Mac from sleeping. This page is about the part that lets your AI assistant use those same tools for you.

What this MCP server does

You ask your AI for something in plain words, like moving a window or reading text off the screen. The AI passes that request to this helper. The helper talks to the Plonk app running on your Mac. Plonk does the work, then hands the result back, and the AI tells you what happened in the chat. Everything stays on your Mac, nothing goes to a cloud service.

What it gives back to you

You get answers in the chat, in plain words. Sometimes that is a list, like the screens and windows you have open. Sometimes it is text pulled off the screen, or a measurement in points and pixels. When you ask it to change something, like moving a window or saving a layout, it tells you what it did.
