# MongoDB Source Connector

MongoDB Source Connector allows you to capture any changes in your MongoDB and
store them as messages on your Kafka topics. In this guide, we will walk you
through creating MongoDB Source Connector with MongoDB database to Upstash
Kafka.

## Get Started

### Create a Kafka Cluster

<Info>
  If you do not have a Kafka cluster and/or topic already, follow [these
  steps](../overall/getstarted) to create one.
</Info>

### Create the Connector

Go to the Connectors tab, and create your first connector by clicking the **New
Connector** button.

Choose **MongoDB Connector Source**

</Frame>

Enter a connector name and MongoDB URI(connection string). Other configrations
are optional. We will skip them for now.

The advanced screen is for any other configuration that the selected connector
supports. At the top of this screen, you can find a link to related
documentation. We can proceed with what we have and click the **Connect** button
directly.

Congratulations! You have created your MongoDB Source Connector to Kafka. Note
that no topics will be created until some data is available on the MongoDB
database.

You can go to **Messages** section of your topic to see latest events as they
are coming from Kafka.
