MongoDB MCP
Query, aggregate and inspect MongoDB and Atlas clusters from your AI agent
About
The MongoDB MCP Server is the official Model Context Protocol server for interacting with MongoDB databases and MongoDB Atlas clusters. It provides database tools for queries, aggregations and schema discovery, plus Atlas tools for cluster management. It is best for developers who want their agent to explore and work with MongoDB data directly.
