MongoDB MCP Server is MongoDB’s official server for databases and MongoDB Atlas.

The MongoDB MCP server lets agents query and manage MongoDB databases and administer MongoDB Atlas. MongoDB publishes it under the Apache-2.0 license. Run locally with npx mongodb-mcp-server, it connects to any deployment through a connection string, and Atlas service-account credentials add cluster, user and access-list management. MongoDB also hosts an Atlas-managed remote server that uses OAuth. The steps below cover Claude Code and Codex.

Database tools find, aggregate, insert, update and inspect schemas and indexes, and the examples start in --readOnly mode.
