What relays_checkDnsPropagation does on Genesis
AI agents call relays_checkDnsPropagation to retrieve information from Genesis without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
domain | string | Yes | Domain to check, e.g. example.com |
Parameters from the server's own tool schema.
Why relays_checkDnsPropagation is rated Low
Even though relays_checkDnsPropagation only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs relays_checkDnsPropagation safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Genesis, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For relays_checkDnsPropagation, this is the rule to start with:
relays_checkDnsPropagation is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Genesis, apply this rule, and every relays_checkDnsPropagation call is checked against it from then on.
