Get the IP whitelist for a user.
AI agents call get_ip_whitelist 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/queries existing security configuration data (IP whitelist) without creating, modifying, or deleting any resources. It is a read-only operation with minimal blast radius if misused—an attacker learning which IPs are whitelisted could inform social engineering or reconnaissance, but cannot directly compromise systems or access restricted resources.
From the tool's definition Tool name 'get_ip_whitelist' and description 'Get the IP whitelist for a user' indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_ip_whitelist 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 get_ip_whitelist:
{
"version": "1",
"default": "deny",
"tools": {
"get_ip_whitelist": {}
}
}get_ip_whitelist is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the IP whitelist for a user. 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 get_ip_whitelist: 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.
get_ip_whitelist 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 get_ip_whitelist 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 get_ip_whitelist. 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.
get_ip_whitelist 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.
Free to start. No card required.
