# sdb-toolbox-config

The `sdb-toolbox-config` tool is primarily used to register and unregister hosts in your cluster. Hosts have to be registered and known before you can run other tools, such as `sdb-deploy` and `sdb-admin` against your cluster.

Some commands like `sdb-deploy setup-cluster` will register the hosts as part of the `setup-cluster` command.

The following is a complete list of operations you can do with `sdb-toolbox-config`:

* [describe-host](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-toolbox-config-commands/describe-host.md)
* [list-hosts](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-toolbox-config-commands/list-hosts.md)
* [register-host](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-toolbox-config-commands/register-host.md)
* [state](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-toolbox-config-commands/state.md)
* [unregister-host](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-toolbox-config-commands/unregister-host.md)
