Multi-Agent Lab is an educational project designed to showcase the core principles of multi-agent systems. It simulates an e-commerce platform with a health consultancy, where various specialized AI agents collaborate to serve customers. The project demonstrates how to implement hierarchical agent structures, integrate diverse AI models like Gemini, Claude, and Llama, and enable agents to execute external tools via the Model Context Protocol (MCP) server. It is ideal for learners and developers looking to understand the practical aspects of building and coordinating sophisticated AI agent ecosystems.
