WHAT IT DOES

What delete_relations does on Enhanced Knowledge Graph Memory Server

AI agents call delete_relations to permanently remove resources in Enhanced Knowledge Graph Memory Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_relations is rated Critical

This tool permanently removes relations from a knowledge graph that is explicitly described as having 'persistent knowledge graph storage'. Deletion operations that cannot be undone fall into the Destructive category. The severity is high because deleting relations in a knowledge graph can break important data connections and dependencies, and the operation cannot be reversed.

From the tool's definition Tool name is 'delete_relations' with description 'Delete multiple relations from the knowledge graph'. The verb 'delete' combined with 'multiple' indicates irreversible removal of data from persistent storage.

RECOMMENDED RULE

The rule that runs delete_relations safely

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

delete_relations Hidden

delete_relations is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
