WHAT IT DOES

What update_entity_name does on Ha Nexus Agent

AI agents use update_entity_name to create or update resources in Ha Nexus Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ha Nexus Agent environment.

RISK

Why update_entity_name is rated Medium

Renaming a registered entity is a write operation: it modifies stored data (the entity's name attribute in the registry) but the change is reversible (can be renamed again). This does not delete data (thus not Destructive), does not move money (not Financial), does not execute arbitrary code (not Execute), and does retrieve or present data without modification (not Read).

From the tool's definition Tool description states 'Rename an entity in the entity registry' — a reversible modification operation that changes metadata/configuration without irreversible deletion or resource destruction.

RECOMMENDED RULE

The rule that runs update_entity_name safely

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

update_entity_name Rate-limited

update_entity_name stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
