Installation

1. Clone this repository:

git clone https://github.com/montumodi/mongodb-atlas-mcp-server.git
cd mongodb-atlas-mcp-server

2. Install dependencies:

npm install

Configuration

Before using the server, you need to set up environment variables with your MongoDB Atlas API credentials:

Required Environment Variables

• MONGODB_ATLAS_PUBLIC_KEY - Your MongoDB Atlas API public key
• MONGODB_ATLAS_PRIVATE_KEY - Your MongoDB Atlas API private key
• MONGODB_ATLAS_PROJECT_ID - Your MongoDB Atlas project/group ID

Optional Environment Variables

• MONGODB_ATLAS_BASE_URL - Atlas API base URL (defaults to https://cloud.mongodb.com/api/atlas/v1.0)

Getting Atlas API Keys

1. Log in to MongoDB Atlas
2. Go to Organization Settings → Access Manager → API Keys
3. Click Create API Key
4. Assign appropriate permissions (Project Read/Write access recommended)
5. Copy the public and private keys
6. Find your Project ID in the project settings

Example Configuration

export MONGODB_ATLAS_PUBLIC_KEY="your-public-key"
export MONGODB_ATLAS_PRIVATE_KEY="your-private-key" 
export MONGODB_ATLAS_PROJECT_ID="your-project-id"

Or create a .env file:

MONGODB_ATLAS_PUBLIC_KEY=your-public-key
MONGODB_ATLAS_PRIVATE_KEY=your-private-key
MONGODB_ATLAS_PROJECT_ID=your-project-id

Usage

Running the Server

npm start

Using with MCP Clients

This server implements the Model Context Protocol and can be used with any MCP-compatible client. The server communicates over stdin/stdout.

Example Tool Usage

Get All Clusters

{
  "name": "cluster_get_all",
  "arguments": {
    "options": {
      "itemsPerPage": 10
    }
  }
}

Create a Database User

{
  "name": "user_create", 
  "arguments": {
    "body": {
      "username": "newuser",
      "password": "securepassword123",
      "roles": [
        {
          "databaseName": "myapp",
          "roleName": "readWrite"
        }
      ],
      "databaseName": "admin"
    }
  }
}

Get Project Events

Get Data Lake Logs (example)

Note: The logs are returned as base64-encoded gzip data in the text response. Decode base64 and then gunzip to read.

{
  "name": "datalake_get_logs_stream",
  "arguments": { "dataLakeName": "MyDataLake" }
}

{
  "name": "events_get_all",
  "arguments": {
    "options": {
      "itemsPerPage": 20,
      "eventType": ["CLUSTER"]
    }
  }
}
