WHAT IT DOES

What create_postgresql_user does on cPanel MCP Server

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

RISK

Why create_postgresql_user is rated Medium

This tool creates a new PostgreSQL user, which is a reversible Write operation that modifies the database user registry. While reversible (the user can be deleted), it establishes authentication credentials and access control configurations on the database system.

From the tool's definition Tool name 'create_postgresql_user' and description 'Create a new PostgreSQL user' directly indicate creation of a database user account, a persistent data modification.

RECOMMENDED RULE

The rule that runs create_postgresql_user safely

PolicyLayer is an MCP gateway: it sits between your AI agents and cPanel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_postgresql_user, this is the rule to start with:

create_postgresql_user Rate-limited

create_postgresql_user stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
