Retrieves a list of DNS records created for a domain name
AI agents call list_dns_records to retrieve information from Vercel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS records for informational purposes only. The verb 'retrieves' and the read-only nature of querying DNS records without side effects clearly categorizes this as a Read operation. The severity is low because accessing DNS record information does not enable unauthorized data modification, deletion, or financial harm—it is purely informational metadata about domain configuration.
From the tool's definition Tool name 'list_dns_records' and description 'Retrieves a list of DNS records created for a domain name' indicate a query operation with no modification or deletion of data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_dns_records:
{
"version": "1",
"default": "deny",
"tools": {
"list_dns_records": {}
}
}list_dns_records is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
