# MongoDB The MongoDB connector is supported both as a source and a destination. It is built into dsync/dsynct and connects directly using a MongoDB connection string. ## Configuration Provide a standard MongoDB connection string as the source or destination argument: ``` mongodb://username:password@host:port ``` This works with MongoDB Atlas (dedicated and serverless), self-managed installations, AWS DocumentDB, and Azure DocumentDB (Cosmos DB vCore). Note that change stream features may need to be explicitly enabled for MongoDB emulators unless you plan to run Initial Sync only. ## Data Type The MongoDB connector uses **BSON**. ## ID Format The ID is a single field called `_id`. By default, MongoDB uses ObjectID values for `_id`, but any BSON type is supported. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
