## About

A `clickhouse-list-tables` tool lists all available tables in a specified
ClickHouse database. It's compatible with the
[clickhouse](../../sources/clickhouse.md) source.

This tool executes the `SHOW TABLES FROM <database>` command and returns a list
of all tables in the specified database that are accessible to the configured
user, making it useful for schema exploration and table discovery tasks.

## Return Value
