Overview

What is MongoDB MCP Server?

A Model Context Protocol (MCP) server that enables AI assistants to interact directly with MongoDB databases and MongoDB Atlas. It provides a set of tools for querying and managing MongoDB data and Atlas infrastructure, requiring either a MongoDB connection string or Atlas API credentials.

How to use MongoDB MCP Server?

The server can be run via npx or Docker, configured through command-line arguments, environment variables, or an MCP client configuration file. For example, add a mcpServers entry to your client’s config file with the command and arguments for your chosen connection method (connection string or Atlas API credentials) and the server will start automatically.

Key features of MongoDB MCP Server

Interact with MongoDB databases using CRUD, aggregation, and indexing tools
Manage MongoDB Atlas organizations, projects, clusters, and access lists
Read-only mode to restrict tools to read and metadata operations only
Disable specific tools, operation types, or entire categories (atlas, mongodb)
Configurable telemetry collection with opt-out support
Docker support for isolated execution without local Node.js

Use cases of MongoDB MCP Server

Let an AI assistant run ad‑hoc MongoDB queries and aggregations in a natural language interface
Automate common Atlas administration tasks like creating free clusters or managing access lists
Enable read‑only analysis of MongoDB data for reporting or auditing without risk of modifications
Integrate database schema exploration and index inspection into AI‑powered development workflows

FAQ from MongoDB MCP Server

What are the prerequisites for using MongoDB MCP Server?

Node.js v20.10.0 or later is required, plus either a MongoDB connection string or Atlas API credentials (service account credentials for Atlas tools). The server will not start unless at least one of these is configured.

How do I connect MongoDB MCP Server to my database?

You can provide a MongoDB connection string via the --connectionString argument, the MDB_MCP_CONNECTION_STRING environment variable, or specify it directly in the MCP client configuration file. The connection string can point to any MongoDB cluster—local or Atlas.

Can I restrict MongoDB MCP Server to read‑only operations?

Yes. Set readOnly to true via the --readOnly command-line argument or the MDB_MCP_READ_ONLY environment variable. This prevents any tool with create, update, or delete operation types from being registered.

What Atlas API tools are available?

Atlas tools include listing organizations, projects, and clusters; creating projects and free clusters; inspecting and modifying access lists; managing database users; and listing alerts. These tools require Atlas service account credentials.

Can I disable specific tools or categories?

Yes. Use the disabledTools configuration option with a list of tool names, operation types (create, update, delete, read, metadata), or categories (atlas, mongodb). Supply it as a comma‑separated string via environment variable or a space‑separated string via command line.

Frequently asked questions

What are the prerequisites for using MongoDB MCP Server?

How do I connect MongoDB MCP Server to my database?

You can provide a MongoDB connection string via the `--connectionString` argument, the `MDB_MCP_CONNECTION_STRING` environment variable, or specify it directly in the MCP client configuration file. The connection string can point to any MongoDB cluster—local or Atlas.

Can I restrict MongoDB MCP Server to read‑only operations?

Yes. Set `readOnly` to `true` via the `--readOnly` command-line argument or the `MDB_MCP_READ_ONLY` environment variable. This prevents any tool with create, update, or delete operation types from being registered.

What Atlas API tools are available?

Can I disable specific tools or categories?

Yes. Use the `disabledTools` configuration option with a list of tool names, operation types (create, update, delete, read, metadata), or categories (`atlas`, `mongodb`). Supply it as a comma‑separated string via environment variable or a space‑separated string via command line.
