# DuckDB UI
> DuckDB UI is a local SQL interface for DuckDB. You can use it with MotherDuck when you want a lightweight SQL workspace backed by the DuckDB CLI and an md: connection.
## How it works with MotherDuck

1. Install and start DuckDB UI from a DuckDB environment that can authenticate to MotherDuck.
2. Store your MotherDuck token in the `motherduck_token` environment variable or use another supported MotherDuck authentication method.
3. Connect to MotherDuck with an `md:` database path and validate the session with a small query.

## Example

```sql
ATTACH 'md:' AS motherduck;
SELECT current_database();
```
