Installation
Prerequisites
Before installing MoltBrain, ensure you have the following:
- Node.js 18+ - Required for running the worker service
- npm or yarn - Package manager for installation
- An AI agent platform - OpenClaw, MoltBook, or Claude Code
- API key - For your LLM provider (Claude, OpenAI, etc.)
Quick Install
Install MoltBrain globally using npm:
