WHAT IT DOES

What vps_scripts_update does on Hostinger

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

RISK

Why vps_scripts_update is rated Medium

The tool modifies an existing post-install script on a VPS, which is a Write operation (creates or modifies data reversibly). It is not Destructive because updates are typically reversible (previous versions may be recoverable). It is not Execute because the tool itself performs the update rather than executing arbitrary code—though the script being updated may later be executed.

From the tool's definition Tool name 'vps_scripts_update' and description 'Update an existing post-install script' indicate modification of existing data (scripts) in a reversible manner.

vps_scripts_update Rate-limited

vps_scripts_update 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.
