WHAT IT DOES

What postgresql_change_privileges does on 1Panel MCP Server

AI agents use postgresql_change_privileges to create or update resources in 1Panel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 1Panel MCP Server environment.

RISK

Why postgresql_change_privileges is rated Medium

Changing privileges modifies database permissions, which is a Write operation (reversible via GRANT/REVOKE). However, it carries high severity because privilege escalation or incorrect privilege assignment could expose sensitive data or allow unauthorized access to the PostgreSQL database.

From the tool's definition 'PostgreSQL: Change privileges' — modifies database access control settings
