WHAT IT DOES

What delete_entity does on Daniel LightRAG MCP Server

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

RISK

Why delete_entity is rated Critical

Deletion of knowledge graph entities cannot be undone and represents permanent data loss. While not as critical as financial operations, the irreversible nature and potential cascading effects on dependent relations and queries in the knowledge graph justify 'high' severity. Confidence is high because the intent is unambiguous from both the name and description.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete an entity from the knowledge graph' — this is an irreversible removal operation.

RECOMMENDED RULE

The rule that runs delete_entity safely

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

delete_entity Hidden

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