daymon

Overview

Daymon is a desktop application for macOS, Windows, and Linux that runs in the system tray and provides an MCP server interface to Claude. It enables users to schedule tasks, create persistent memories, set up file watchers, and define specialized worker agents that can operate autonomously in the background. The application uses Claude Desktop or Claude Code as its interface while handling all the automation locally without requiring API keys or cloud services.
