List all DNS domains in your Vultr account
AI agents call list_dns_domains to retrieve information from Vultr MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries DNS domain information from the Vultr account with no side effects. It performs a non-destructive read operation only, consistent with the 'Read' category definition for list/fetch operations. The blast radius is minimal—an AI agent misusing this tool could only discover domain names already owned by the account.
From the tool's definition Tool name 'list_dns_domains' and description 'List all DNS domains in your Vultr account' indicates data retrieval without modification or execution.
Documented attack patterns abuse exactly the kind of access list_dns_domains gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_dns_domains:
{
"version": "1",
"default": "deny",
"tools": {
"list_dns_domains": {}
}
}list_dns_domains is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all DNS domains in your Vultr account. It is categorised as a Read tool in the Vultr MCP MCP Server, which means it retrieves data without modifying state.
Register the Vultr MCP server in PolicyLayer and add a rule for list_dns_domains: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vultr MCP. Nothing to install.
list_dns_domains is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_dns_domains rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_dns_domains. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_dns_domains is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
