+## 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
+3. Configuration file
+4. Default values
+
+### Configuration Options
+
+| Option             | Description                                                                 |
+| ------------------ | --------------------------------------------------------------------------- |
+| `apiClientId`      | Atlas API client ID for authentication                                      |
+| `apiClientSecret`  | Atlas API client secret for authentication                                  |
+| `stateFile`        | Path to store application state (default ~/.mongodb/mongodb-mcp/state.json) |
+| `connectionString` | MongoDB connection string for direct database connections                   |
+
+### 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 [cloud.mongodb.com](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"
+
+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 (Optional but recommended):**
+
+   - 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
+
+#### Configuration File
+
+Create a JSON configuration file at one of these locations:
+
+- Linux/macOS: `/etc/mongodb-mcp.conf`
+- Windows: `%LOCALAPPDATA%\mongodb\mongodb-mcp\mongodb-mcp.conf`
+
+Example configuration file:
+
+```json
+{
+  "apiClientId": "your-atlas-client-id",
+  "apiClientSecret": "your-atlas-client-secret",
+  "connectionString": "mongodb+srv://username:[email protected]/myDatabase"
+}
+```
+
+#### Environment Variables
+
+Set environment variables with the prefix `MDB_MCP_` followed by the option name in uppercase with underscores:
+
+```shell
+# Set Atlas API credentials
+export MDB_MCP_API_CLIENT_ID="your-atlas-client-id"
+export MDB_MCP_API_CLIENT_SECRET="your-atlas-client-secret"
+
+# Set a custom MongoDB connection string
+export MDB_MCP_CONNECTION_STRING="mongodb+srv://username:[email protected]/myDatabase"
+```
+
+#### Command-Line Arguments
+
+Pass configuration options as command-line arguments when starting the server:
+
+```shell
+node dist/index.js --apiClientId="your-atlas-client-id" --apiClientSecret="your-atlas-client-secret" --connectionString="mongodb+srv://username:[email protected]/myDatabase"
+```
