WHAT IT DOES

What set_dnssec_nsec3 does on cPanel MCP Server

AI agents use set_dnssec_nsec3 to create or update resources in cPanel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your cPanel MCP Server environment.

RISK

Why set_dnssec_nsec3 is rated Medium

This tool modifies DNS security configuration for a domain by enabling NSEC3 hashing, which is a reversible configuration change. It does not delete or destroy data (not Destructive), does not execute arbitrary code (not Execute), and has no financial impact (not Financial). While DNSSEC misconfigurations could cause DNS resolution failures and broad service disruption, the action itself is Write-category.

From the tool's definition set_dnssec_nsec3 tool enables DNSSEC NSEC3 feature for a domain—'Enable NSEC3 for a DNSSEC domain'

RECOMMENDED RULE

The rule that runs set_dnssec_nsec3 safely

PolicyLayer is an MCP gateway: it sits between your AI agents and cPanel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_dnssec_nsec3, this is the rule to start with:

set_dnssec_nsec3 Rate-limited

set_dnssec_nsec3 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.
