MongoDB MCP Server Docker Image

MongoDB MCP Server

A Model Context Protocol server for interacting with MongoDB Databases and MongoDB Atlas.

Prerequisites

• Node.js (v20 or later)

shell
node -v

• A MongoDB connection string or Atlas API credentials, the Server will not start unless configured.
  • Service Accounts Atlas API credentials are required to use the Atlas tools. You can create a service account in MongoDB Atlas and use its credentials for authentication. See Atlas API Access for more details.
  • If you have a MongoDB connection string, you can use it directly to connect to your MongoDB instance.

Setup

Quick Start

Most MCP clients require a configuration file to be created or modified to add the MCP server.

Note: The configuration file syntax can be different across clients. Please refer to the following links for the latest expected syntax:

• Windsurf:https://docs.windsurf.com/windsurf/mcp
• VSCode: https://code.visualstudio.com/docs/copilot/chat/mcp-servers
• Claude Desktop: https://modelcontextprotocol.io/quickstart/user
• Cursor: https://docs.cursor.com/context/model-context-protocol

You may provide either a MongoDB connection string OR Atlas API credentials:

Option A: No configuration

shell
docker run --rm -i \
  mongodb/mongodb-mcp-server:latest

Option B: With MongoDB connection string

shell
docker run --rm -i \
  -e MDB_MCP_CONNECTION_STRING="mongodb+srv://username:password@cluster.mongodb.net/myDatabase" \
  mongodb/mongodb-mcp-server:latest

Option C: With Atlas API credentials

shell
docker run --rm -i \
  -e MDB_MCP_API_CLIENT_ID="your-atlas-service-accounts-client-id" \
  -e MDB_MCP_API_CLIENT_SECRET="your-atlas-service-accounts-client-secret" \
  mongodb/mongodb-mcp-server:latest

Configuration

The MongoDB MCP Server can be configured using multiple methods, with the following precedence (highest to lowest):

1. Command-line arguments
2. Environment variables

Configuration Options

Log Path

Default log location is as follows:

• Windows: %LOCALAPPDATA%\mongodb\mongodb-mcp\.app-logs
• macOS/Linux: ~/.mongodb/mongodb-mcp/.app-logs

Disabled Tools

You can disable specific tools or categories of tools by using the disabledTools option. This option accepts an array of strings, where each string can be a tool name, operation type, or category.

The way the array is constructed depends on the type of configuration method you use:

• For environment variable configuration, use a comma-separated string: export MDB_MCP_DISABLED_TOOLS="create,update,delete,atlas,collectionSchema".
• For command-line argument configuration, use a space-separated string: --disabledTools create update delete atlas collectionSchema.

Categories of tools:

• atlas - MongoDB Atlas tools, such as list clusters, create cluster, etc.
• mongodb - MongoDB database tools, such as find, aggregate, etc.

Operation types:

• create - Tools that create resources, such as create cluster, insert document, etc.
• update - Tools that update resources, such as update document, rename collection, etc.
• delete - Tools that delete resources, such as delete document, drop collection, etc.
• read - Tools that read resources, such as find, aggregate, list clusters, etc.
• metadata - Tools that read metadata, such as list databases, list collections, collection schema, etc.

Read-Only Mode

The readOnly configuration option allows you to restrict the MCP server to only use tools with "read" and "metadata" operation types. When enabled, all tools that have "create", "update" or "delete" operation types will not be registered with the server.

This is useful for scenarios where you want to provide access to MongoDB data for analysis without allowing any modifications to the data or infrastructure.

You can enable read-only mode using:

• Environment variable: export MDB_MCP_READ_ONLY=true
• Command-line argument: --readOnly

When read-only mode is active, you'll see a message in the server logs indicating which tools were prevented from registering due to this restriction.

Telemetry

The telemetry configuration option allows you to disable telemetry collection. When enabled, the MCP server will collect usage data and send it to MongoDB.

You can disable telemetry using:

• Environment variable: export MDB_MCP_TELEMETRY=disabled
• Command-line argument: --telemetry disabled
• DO_NOT_TRACK environment variable: export DO_NOT_TRACK=1

Atlas API Access

To use the Atlas API tools, you'll need to create a service account in MongoDB Atlas:

1. Create a Service Account:

   • Log in to MongoDB Atlas at https://cloud.mongodb.com
   • Navigate to Access Manager > Organization Access
   • Click Add New > Applications > Service Accounts
   • Enter name, description and expiration for your service account (e.g., "MCP, MCP Server Access, 7 days")
   • Select appropriate permissions (for full access, use Organization Owner)
   • Click "Create"

To learn more about Service Accounts, check the https://www.mongodb.com/docs/atlas/api/service-accounts-overview/.

2. Save Client Credentials:

   • After creation, you'll be shown the Client ID and Client Secret
   • Important: Copy and save the Client Secret immediately as it won't be displayed again

3. Add Access List Entry:

   • Add your IP address to the API access list

4. Configure the MCP Server:

   • Use one of the configuration methods below to set your apiClientId and apiClientSecret

Configuration Methods

Environment Variables

Set environment variables with the prefix MDB_MCP_ followed by the option name in uppercase with underscores:

shell
# Set Atlas API credentials (via Service Accounts)
export MDB_MCP_API_CLIENT_ID="your-atlas-service-accounts-client-id"
export MDB_MCP_API_CLIENT_SECRET="your-atlas-service-accounts-client-secret"

# Set a custom MongoDB connection string
export MDB_MCP_CONNECTION_STRING="mongodb+srv://username:password@cluster.mongodb.net/myDatabase"

export MDB_MCP_LOG_PATH="/path/to/logs"
