Why vps_set_nameservers is rated Medium
This tool modifies DNS nameserver settings for a VPS, which is a reversible configuration change. It does not delete or create infrastructure (ruling out Destructive/Execute for creation), nor does it move money. However, the impact is high because misconfiguring nameservers can break domain resolution and service availability, affecting critical infrastructure.
From the tool's definition Tool name 'vps_set_nameservers' and description 'Set nameservers for a virtual machine' indicate modification of DNS configuration for infrastructure.
Attacks that exploit this kind of access
The rule that runs vps_set_nameservers safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hostinger, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vps_set_nameservers, this is the rule to start with:
vps_set_nameservers 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Hostinger, apply this rule, and every vps_set_nameservers call is checked against it from then on.
