PowerShell, Microsoft’s automation framework, provides powerful tools for managing databases. This guide demonstrates two methods for connecting to MongoDB, a popular NoSQL database, using PowerShell: leveraging the simplified Mdbc module and utilizing the MongoDB .NET driver directly.

Connecting to MongoDB with the Mdbc Module
The Mdbc module offers a user-friendly interface for interacting with MongoDB. Its streamlined commands simplify common database operations.
1. Installation:
Open PowerShell as an administrator and run:
Install-Module -Name Mdbc
If you encounter errors, adjust your execution policy:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
2. Connection:
Construct your connection string (e.g., mongodb://localhost:27017 for a local instance or mongodb://<username>:<password>@<host>:<port>/<database>?authSource=<authdb> for remote access). Then connect:
$connection = Connect-Mdbc -ConnectionString "your_connection_string"
3. Basic Operations:
After connecting, perform actions like:
- List Databases:
Get-MdbcDatabase -Connection $connection - List Collections:
Get-MdbcCollection -Connection $connection -Database "your_database_name" - Insert a Document:
$document = @{ Name = "Example"; Value = 123 }
Insert-MdbcDocument -Connection $connection -Database "your_database_name" -Collection "your_collection_name" -Document $document
Get-MdbcDocument -Connection $connection -Database "your_database_name" -Collection "your_collection_name" -Query @{ Name = "Example" }
Remember to replace placeholders with your actual values. Refer to the Mdbc module documentation for advanced commands.
Connecting to MongoDB with the .NET Driver
For more complex scenarios or fine-grained control, use the official MongoDB .NET driver. This requires more coding but offers greater flexibility.
1. Installation:
Install the MongoDB .NET driver via NuGet Package Manager (within a .NET project) or download the DLLs and reference them in your PowerShell script.
2. Connection and Operations:
This involves using the driver’s classes directly. While a complete example is beyond this article’s scope, the general process includes creating a MongoClient object, accessing databases and collections, and using methods like InsertOneAsync or FindAsync. This method requires a deeper understanding of the driver’s API.
Conclusion
Both methods provide valid ways to connect to MongoDB using PowerShell. Mdbc offers simplicity, while the .NET driver provides advanced control. Select the approach best suited for your needs and expertise. Always prioritize secure connection string handling and exception management.
