WHAT IT DOES

What get_entity_versions does on Enhanced Knowledge Graph Memory Server

AI agents call get_entity_versions to retrieve information from Enhanced Knowledge Graph Memory 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 get_entity_versions is rated Low

This is a straightforward data retrieval operation that queries the knowledge graph to fetch version history of an entity. It has no side effects—it only reads and returns existing version information. The mention of 'contradiction detection' is a passive analytical feature, not an active operation that modifies state. This clearly falls under the Read category with low severity and high confidence.

From the tool's definition Tool name 'get_entity_versions' and description 'Get the latest version of an entity' indicates retrieval of existing data. The function returns information about entity versions without modifying, deleting, or executing any operations.

RECOMMENDED RULE

The rule that runs get_entity_versions safely

get_entity_versions Allowed

get_entity_versions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
