WHAT IT DOES

What delete_postgresql_instance does on Linode MCP Server

AI agents call delete_postgresql_instance to permanently remove resources in Linode MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_postgresql_instance is rated Critical

Deleting a database instance is irreversible and destroys all data stored within it. This action cannot be undone and represents complete data loss, making it the most severe risk category. The blast radius is critical because an agent error or prompt injection could result in permanent loss of production data, backups, and associated configurations.

From the tool's definition Tool name is 'delete_postgresql_instance' and description states 'Delete a PostgreSQL database instance' — the word 'Delete' indicates irreversible removal of a database.
