WHAT IT DOES

What create_ipv4 does on Vultr MCP

AI agents use create_ipv4 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.

RISK

Why create_ipv4 is rated Medium

This tool creates a new IPv4 address, which is a reversible write operation on cloud infrastructure. It modifies instance networking configuration but does not delete data or execute arbitrary code. Severity is medium because misconfigured IP allocation could cause service disruptions or unexpected infrastructure costs, but the action is recoverable by deleting the created IP address.

From the tool's definition Tool name 'create_ipv4' and description 'Create a new IPv4 address for an instance' indicate resource creation/modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_ipv4 safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vultr MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_ipv4, this is the rule to start with:

create_ipv4 Rate-limited

create_ipv4 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Vultr MCP, apply this rule, and every create_ipv4 call is checked against it from then on.

FAQ

Questions about create_ipv4

What does the create_ipv4 tool do? +

How do I enforce a policy on create_ipv4? +

Register the Vultr MCP server in PolicyLayer and add a rule for create_ipv4: 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.

What risk level is create_ipv4? +

create_ipv4 is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_ipv4? +

Yes. Add a rate_limit block to the create_ipv4 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.

How do I block create_ipv4 completely? +

Set action: deny in the PolicyLayer policy for create_ipv4. 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.

What MCP server provides create_ipv4? +

create_ipv4 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.
