Mecum
Mecum is an AI agent desktop workspace that runs workers in apps on macOS while the user works.
Mecum is a macOS desktop application that provides a workspace for AI agents to operate native desktop applications. It routes agent input to app windows moved to a virtual display, allowing users to continue using their Mac simultaneously. The system uses Swift-based packages for window drivers, text perception pipelines, app control mapping, and interaction memory. Users can connect Claude Code or Codex through the Model Context Protocol to execute tasks in apps that lack APIs or accessibility trees. It supports frameworks such as AppKit, Chromium, Electron, and Qt.
