WHAT IT DOES

What list_postgresql_users does on cPanel MCP Server

AI agents call list_postgresql_users to retrieve information from cPanel MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_postgresql_users is rated Low

This tool performs a read-only operation to enumerate existing PostgreSQL users. It has no side effects, does not modify data, execute commands, or delete anything. The blast radius is minimal—exposing a list of database users is an information disclosure risk but not immediately dangerous without additional tools to modify those users or access their accounts.

From the tool's definition Tool name 'list_postgresql_users' and description 'List all PostgreSQL users' indicate a query operation that retrieves information without modification or execution of code.
