AI agents use create_record to create or update resources in Vultr MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vultr MCP environment.
The 'create_record' tool creates new records within Vultr's infrastructure (most likely DNS records given the presence of DNS-related tools). This is a Write operation as it creates new data that can be modified or deleted later. Severity is high because misconfigured DNS records could disrupt service availability or enable security attacks like domain hijacking.
From the tool's definition Tool name 'create_record' indicates creation of a new record, likely DNS or database record based on sibling tools 'analyze_dns_records' showing this server manages DNS infrastructure.
Documented attack patterns abuse exactly the kind of access create_record 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 create_record:
{
"version": "1",
"default": "deny",
"tools": {
"create_record": {
"limits": [
{
"counter": "create_record_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_record stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

create_record. It is categorised as a Write tool in the Vultr MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Vultr MCP server in PolicyLayer and add a rule for create_record: 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.
create_record is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_record 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 create_record. 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.
create_record 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.
