Either the `sqlcmd` or `mssql-cli` command-line clients should be available in `PATH` in order to be able to connect. `tsh` attempts to run `sqlcmd` first and, if it's not present on the `PATH`, runs `mssql-cli`. If you have neither command-line clients available on your system, you can run the following command to start a local proxy server that you can connect to with your SQL Server client: ```code $ tsh proxy db --db-user=teleport --tunnel sqlserver ``` Read the [Database GUI Clients](../../connect-your-client/gui-clients.mdx#sql-server-with-azure-data-studio) guide for how to connect your DB GUI client to the local proxy.
