Overview

AI-generated overview

A local macOS computer-use MCP server that gives an assistant screenshots, accessibility trees and app actions on the user's own machine.

What you can do
Capture screenshots of the macOS desktop so the assistant can see what is on screen. Read accessibility (AX) trees to understand windows, controls and app structure. Perform app actions on the local machine, such as interacting with running applications. Runs as a local process over stdio, so it works only on the machine where it is installed.
When to use it
Useful when an assistant needs to inspect or operate macOS applications and the desktop directly, for example to look at a window, read its controls, or carry out actions in a local app. Only relevant for macOS users who want on-device computer control rather than remote services.
Requirements
Runs as a local npm package over stdio on macOS; a Node.js runtime is needed. The manifest declares no authentication, environment variables or headers. Desktop-only: it does not run as a web executable.
Before you install
It can take screenshots and read accessibility trees of the desktop, which may expose whatever is visible on screen, including private or sensitive content. App actions can change or delete data in local applications. Review what the assistant is allowed to do before granting control of the desktop.

Installation

In SourceWeft

  1. Open RaroCUA in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
