# Silo Client Settings
LLMS index: [llms.txt](/llms.txt)
---
This page covers settings for the [MinIO Client](/reference/minio-mc/#minio-client).
You can establish or modify settings by defining:
- an *environment variable* on the host system prior to starting or restarting the MinIO Server. Refer to your operating system’s documentation for how to define an environment variable.
- a *configuration setting* using [`mc admin config set`](/reference/minio-mc-admin/mc-admin-config/#mc.admin.config.set).
If you define both an environment variable and the similar configuration setting, MinIO uses the environment variable value.
Some settings have only an environment variable or a configuration setting, but not both.
## Settings {#settings}
### Host Credentials {#host-credentials}
Use this setting to add a temporary alias to use for *mc* commands. For example, for use with scripting.
The temporary alias uses the [AWS s3v4 signature](https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html).
**Environment Variable**
##### `MC_HOST_` {#envvar.MC_HOST_-ALIAS}
*envvar*
Replace `` at the end of the environment variable with the `alias` to set the host for.
**Configuration Setting**
This setting does not have a configuration setting option.
Use [`mc alias set`](/reference/minio-mc/mc-alias-set/#command-mc.alias.set) to configure an [alias](/reference/minio-mc/mc-alias-set/#alias).
#### Examples {#examples}
