MCP.Pizza Chef: mediar-ai

Built for macOS alone, it opens or switches to whichever app you name, reads the real buttons and fields on screen through Apple's accessibility features, then clicks, types, or presses keys on your behalf. Because it reads actual controls rather than pixels, it is steadier than screenshot-guessing approaches. Setup is hands-on: you compile the program yourself with Swift and point Claude Desktop at the file it produces. Nothing is charged for it, but macOS will ask your permission first.

Official website: https://macos-use.dev/

Model Context Protocol (MCP) server in Swift. It allows controlling macOS applications by leveraging the accessibility APIs, primarily through the MacosUseSDK.

You can use it in Claude Desktop or other compatible MCP-client.

The server listens for MCP commands over standard input/output (stdio) and exposes several tools to interact with applications.

mcp-server-macos-use FAQ

Is this still maintained?

Quietly. The most recent change was April 2026, so it is slow-moving rather than abandoned, and no replacement is named.

Does it work on Windows or Linux?

No. It leans on Apple's accessibility features and runs only on macOS.

Which apps can I drive it from?

Claude Desktop is the documented setup, and any assistant that reads a standard MCP settings file can use it.

Do I need a paid key?

Not for this. You still pay for whichever assistant you point at it.

Can I use this to fill in a form in an app that has no shortcuts?

Yes — that is the main point of it. It types and clicks in the real window like a person would.

How hard is setup?

Developer-level. You build the program from source with Swift, then paste its file path into your assistant's settings.
