WHAT IT DOES

What update_drive does on Huly

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

RISK

Why update_drive is rated Medium

The tool modifies Drive metadata fields (name, description, privacy settings, archive status, auto-join flag) which are all reversible changes. This qualifies as Write rather than Read (it modifies state), Destructive (not irreversible), Execute (not triggering external code), or Financial (no monetary impact).

From the tool's definition Tool description states 'Update safe metadata on an existing Drive: name, description, private, archived, or autoJoin.' These are reversible modifications to Drive properties without destructive deletion or irreversible overwrites.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_drive safely

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

update_drive Rate-limited

update_drive 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.
