WHAT IT DOES

What dns does on OpenClaw

AI agents call dns to retrieve information from OpenClaw without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why dns is rated Low

DNS helpers typically perform lookups and queries to resolve hostnames or discover services. The description mentions 'discovery' which aligns with read/query operations. No write, execute, or destructive behavior is indicated.

From the tool's definition 'DNS helpers for wide-area discovery' implies querying/resolving DNS records, which is a read operation

RECOMMENDED RULE

The rule that runs dns safely

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

dns Allowed

dns is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect OpenClaw, apply this rule, and every dns call is checked against it from then on.
