# MongoDB
ToolJet can connect to MongoDB to read and write data.
## Connection
Please make sure the host/ip of the database is accessible from your VPC if you have self-hosted ToolJet. If you are using ToolJet cloud, please whitelist our IP.
To add a new MongoDB, click on the `+` button on data sources panel at the left-bottom corner of the app editor. Select MongoDB from the modal that pops up.
ToolJet requires the following to connect to your MongoDB.
- **Host**
- **Port**
- **Username**
- **Password**
It is recommended to create a new MongoDB user so that you can control the access levels of ToolJet.
Click on 'Test connection' button to verify if the credentials are correct and that the database is accessible to ToolJet server. Click on 'Save' button to save the data source.
## Querying MongoDB
Click on `+` button of the query manager at the bottom panel of the editor and select the database added in the previous step as the data source. Select the operation that you want to perform and click 'Save' to save the query.
Click on the 'run' button to run the query. NOTE: Query should be saved before running.
:::tip
Query results can be transformed using transformations. Read our transformations documentation to see how: [link](/docs/tutorial/transformations)
