Hosting

Both: local server and MongoDB Atlas Managed MCP Server

Transport

stdio (local); remote MCP (Atlas Managed; client setup documented by MongoDB)

Endpoint

Local process; no hosted endpoint documented

Authentication

Local server uses a MongoDB connection string for database access and optional Atlas service-account API credentials for Atlas management tools. Atlas Managed uses MongoDB Atlas authentication/App Connections and the user's permitted Atlas access.

Requirements

• MongoDB deployment and connection URI for local database access
• Node.js 22.12 or later recommended for local setup
• Atlas account / service account credentials only for Atlas management functions that require them
• Docker required for local Atlas deployment tools
• Enable read-only mode unless write access is specifically needed

Setup steps

1. Choose between MongoDB Atlas Managed MCP and Local MCP; they are distinct deployment modes with different tool availability.
2. For local mode, use MongoDB's guided setup: `npx mongodb-mcp-server@latest setup`, or follow the documented Docker setup.
3. Select the intended MCP client, enable read-only mode unless writes are needed, and provide the MongoDB URI through local configuration. Never paste the URI or credentials into chat.
4. Add optional Atlas service-account credentials only if using Atlas administration tools; grant the minimum documented permissions.
5. For Atlas Managed mode, configure MongoDB Atlas App Connections in a supported client and complete the Atlas sign-in/authorization flow.
6. Verify using a read-only query such as listing databases or a bounded `find` request.

MongoDB documents separate Atlas, local Atlas deployment, database, and Assistant tool families. Availability differs by Atlas Managed versus Local mode and configured credentials. The stored exact names are representative and are not a complete merged inventory.

This server’s available tools can vary by account, permissions, or configuration. The list shown is not its full runtime catalog.

• Exact tools depend on deployment mode, credentials, read-only settings, and enabled configuration.
• Database tools can insert, update, or delete data when write access is enabled; use read-only mode unless writes are needed.
• Atlas performance-advisor tools have documented Atlas role and cluster-tier requirements.
• Connection strings and service-account secrets must remain local and must not be exposed in prompts or logs.

• official tool reference

  MongoDB’s official reference separates Atlas management, local Atlas deployments, database operations, and Assistant knowledge tools. Tool availability differs between Atlas Managed and Local deployments and depends on configured credentials; the 11 stored names are representative, not a complete merged catalog.
