WHAT IT DOES

What create_clickhouse_database does on Coolify

AI agents use create_clickhouse_database to create or update resources in Coolify, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Coolify environment.

RISK

Why create_clickhouse_database is rated Medium

This tool creates a new Clickhouse database, which is a write operation that adds infrastructure/data structures. While the action itself is reversible (databases can be deleted), the creation of a database can have significant operational impact on a system, justifying 'high' severity.

From the tool's definition Tool name explicitly states 'create_clickhouse_database' and description confirms it creates a database. The verb 'create' indicates data structure creation, a reversible write operation.
