create_forwarding_rule
AI agents use create_forwarding_rule 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.
This tool creates a new network forwarding rule, which is a reversible write operation that modifies infrastructure configuration. While the empty description limits certainty, the 'create_' prefix and Vultr context (networking service) clearly indicate it writes/creates new resources rather than reading, executing arbitrary code, or destructively deleting data.
From the tool's definition Tool name 'create_forwarding_rule' indicates creation of a network forwarding rule. The prefix 'create_' explicitly indicates a write operation that adds new configuration to Vultr infrastructure.
Documented attack patterns abuse exactly the kind of access create_forwarding_rule 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_forwarding_rule:
{
"version": "1",
"default": "deny",
"tools": {
"create_forwarding_rule": {
"limits": [
{
"counter": "create_forwarding_rule_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_forwarding_rule 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_forwarding_rule. 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_forwarding_rule: 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_forwarding_rule 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_forwarding_rule 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_forwarding_rule. 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_forwarding_rule 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.
