Determine which authentication method you want to use:
- If you want to connect directly to a MongoDB instance, you’ll need a MongoDB connection string.
- If you want to use MongoDB Atlas tools (for organization, clusters, or database users), you’ll need to create a Service Account API client ID and secret from MongoDB Atlas.
Obtain your MongoDB connection string (for direct database access):
- If you are using MongoDB Atlas:
- Log in to MongoDB Atlas.
- Select your project and cluster.
- Click Connect.
- Choose Connect your application.
- Copy the connection string (looks like
mongodb+srv://username:password@cluster.mongodb.net/myDatabase). - Replace
username,password, andmyDatabasewith your actual database credentials.
- If you are using a self-hosted MongoDB:
- Your connection string will be in the format:
mongodb://username:password@host:port/database.
- Your connection string will be in the format:
- If you are using MongoDB Atlas:
To use Atlas API tools, obtain API credentials:
- Create a Service Account in MongoDB Atlas:
- Log in to MongoDB Atlas.
- Navigate to Access Manager > Organization Access.
- Click Add New > Applications > Service Accounts.
- Enter a name, description, and expiration (e.g., “MCP, MCP Server Access, 7 days”).
- Assign only the minimum necessary permissions for your use case.
- Click Create.
- Save Client Credentials:
- After creation, you’ll see the Client ID and Client Secret.
- Copy and save the Client Secret immediately; it will not be shown again.
- Add your IP address to the Atlas API access list.
- Still in the Atlas dashboard, go to API Access/Access List.
- Add your current IP address or a range to allow API access.
- Assign minimum permissions for required operations:
- For basic reading, “Project Read Only” (Project level) is generally sufficient.
- For advanced tooling, follow the roles table in the README.
- Create a Service Account in MongoDB Atlas:
Fill in values in the FastMCP connection interface:
- Click the Install Now button in your environment.
- Use the FastMCP interface to add your keys:
- For MongoDB connection string: Enter it into the field labeled
MDB_MCP_CONNECTION_STRING. - For Atlas API: Enter your
MDB_MCP_API_CLIENT_IDandMDB_MCP_API_CLIENT_SECRETin the provided fields.
- For MongoDB connection string: Enter it into the field labeled
- Only one method is required: either a connection string (for direct DB access) or API credentials (for Atlas operations).
Finish Setup:
- Save changes in FastMCP.
- The server will now have access to your MongoDB database or Atlas project according to the credentials provided.
Summary Table of Required Information:
| Option | FastMCP Field(s) | Where to get it |
|---|---|---|
| Direct MongoDB | MDB_MCP_CONNECTION_STRING |
MongoDB Atlas UI or self-hosted config |
| Atlas API (recommended) | MDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET |
Atlas Service Account setup in Atlas UI |
