MongoDB Atlas Vector Search
Native vector search built into MongoDB Atlas, letting teams store operational data, metadata, and vector embeddings in one place.
Last verified:
Atlas Vector Search is MongoDB's native vector search capability, embedded directly in the Atlas document database rather than requiring a separate vector store. It supports ANN/ENN search via the $vectorSearch aggregation stage, hybrid lexical+vector queries, automated embeddings and reranking powered by Voyage AI, and is available on free (M0), Flex, and Dedicated clusters, plus self-managed Enterprise Advanced and Community editions. MongoDB Inc. is a public company (NASDAQ: MDB) headquartered in New York City.
