Build an Agentic Event Venue Operator with MongoDB Atlas, Voyage, and LangGraph

MongoDB and partners built a demo event-venue operator using MongoDB Atlas, Voyage AI embeddings and LangGraph that handles real-time decisions during a fictional tennis tournament. The agent reads current venue state, retrieves prior visitor and weather memories, and writes outcomes back to Atlas for future use. The open-source reference app runs locally or on Vercel and combines vector search, hybrid retrieval and optional Langfuse tracing.
