Why dns_dnssec_info needs a policy

This tool retrieves and queries DNSSEC configuration data for a DNS zone. It performs no data modification, deletion, code execution, or financial operations. The blast radius of misuse is minimal—an attacker could only gather information about DNSSEC configurations, which does not compromise the DNS infrastructure itself without further tools. This is a straightforward Read category tool.

From the tool's definition Tool name 'dns_dnssec_info' and description 'Get DNSSEC properties for a zone' indicate a retrieval operation.

POLICY

How to control dns_dnssec_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Technitium MCP Secure, and nothing reaches the server without passing your rules. This is the rule we recommend for dns_dnssec_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "dns_dnssec_info": {}
  }
}

dns_dnssec_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Technitium MCP Secure — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
