Exposes MongoDB collections, aggregation pipelines, and Atlas tooling as MCP resources and tools. Maintained by mongodb-js.

What it does

  • Official MongoDB-maintained MCP server — exposes Atlas and self-hosted cluster capabilities as tools and resources
  • Built-in schema discovery, query tools, and Atlas administration surfaces
  • Maintained by the mongodb-js team

When to use it

Let Claude inspect and query your MongoDB data in place — explore collections, prototype aggregation pipelines, and sanity-check schemas without leaving the conversation.

Getting started

npx -y mongodb-mcp-server

Requires a MongoDB connection string (Atlas or self-hosted) via the MDB_MCP_CONNECTION_STRING env var.

Things to know

Grants read (and optionally write) database access to an agent. Prefer a read-only connection string, and if you enable write tools, scope them to a dedicated dev database.
