The Workbench is DBHub's built-in web interface for interacting with your database tools. It provides a visual way to execute queries and test custom tools without requiring an MCP client.

## Starting the Workbench
The Workbench is available when running DBHub with HTTP transport:
```bash
npx @bytebase/dbhub --transport http --port 8080 --dsn "postgres://..."
```
Then open `http://localhost:8080` in your browser.
<Tip>
Try demo mode to explore the Workbench without setting up a database:
```bash
npx @bytebase/dbhub --transport http --port 8080 --demo
```
