WHAT IT DOES

What list_drives does on Huly

AI agents call list_drives to retrieve information from Huly without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_drives is rated Low

This tool retrieves or queries information about drive spaces without creating, modifying, or deleting any data. It is a pure read operation used for information discovery. The blast radius of misuse is minimal—an attacker could enumerate drives but cannot alter or access unauthorized data through this tool alone.

From the tool's definition Tool name 'list_drives' and description 'List Huly Drive spaces' indicate a retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_drives safely

list_drives Allowed

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