WHAT IT DOES

What postgresql_list_databases does on 1Panel MCP Server

AI agents call postgresql_list_databases to retrieve information from 1Panel 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 postgresql_list_databases is rated Low

This tool performs a read-only operation on PostgreSQL to list existing databases. It has no side effects, does not modify data, and does not execute arbitrary commands. The blast radius of misuse is minimal—an AI agent could at most discover database names, which is informational only. This is a standard diagnostic/inspection tool typical of infrastructure management systems.

From the tool's definition Tool name 'postgresql_list_databases' and description 'PostgreSQL: List databases' indicate a query operation that retrieves and enumerates database names without modifying any data.
