WHAT IT DOES

What import_zone_file does on Vultr MCP

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

RISK

Why import_zone_file is rated Medium

Importing a zone file creates or modifies DNS records in bulk, which is a reversible write operation. While not destructive on its own, it has high severity due to potential blast radius: misconfigured DNS imports could redirect traffic, disrupt services, or enable DNS hijacking.

From the tool's definition Tool name 'import_zone_file' indicates importing DNS zone file data. Sibling tools include 'add_export' and 'analyze_dns_records', confirming DNS management context. Zone file imports create or modify DNS records.

RECOMMENDED RULE

The rule that runs import_zone_file safely

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

import_zone_file Rate-limited

import_zone_file 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.
