Moltbot is a self-hosted Node.js message router that connects multiple chat platforms to AI agents capable of executing real actions. The architecture consists of channel adapters that normalize messages from different platforms, a Gateway that routes messages, an agent runtime that processes requests and decides actions, and a tool execution layer. The system translates messages from apps like WhatsApp or Telegram into a unified format, sends them to an AI agent, executes necessary tools (like sending emails or running shell commands), and returns responses through the same path. Security considerations include binding to localhost by default, implementing allow-listing mechanisms, and understanding that tools run with your machine's permissions.
