WHAT IT DOES

What create_vpc_subnet does on Linode MCP Server

AI agents use create_vpc_subnet to create or update resources in Linode MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Linode MCP Server environment.

RISK

Why create_vpc_subnet is rated Medium

This tool creates a new network subnet, which modifies cloud infrastructure configuration. It is reversible (the subnet can be deleted), so it falls under Write rather than Destructive. However, it has high severity because misuse could create network segments that expose or isolate resources unexpectedly, potentially affecting application availability or security posture.

From the tool's definition Tool name is 'create_vpc_subnet' and description states 'Create a new subnet in a VPC', indicating creation of a new networking resource.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_vpc_subnet safely

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

create_vpc_subnet Rate-limited

create_vpc_subnet 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 Linode MCP Server, apply this rule, and every create_vpc_subnet call is checked against it from then on.

FAQ

Questions about create_vpc_subnet

What does the create_vpc_subnet tool do? +

Create a new subnet in a VPC. It is categorised as a Write tool in the Linode MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_vpc_subnet? +

Register the Linode MCP Server MCP server in PolicyLayer and add a rule for create_vpc_subnet: 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 Linode MCP Server. Nothing to install.

What risk level is create_vpc_subnet? +

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

Can I rate-limit create_vpc_subnet? +

Yes. Add a rate_limit block to the create_vpc_subnet 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_vpc_subnet completely? +

Set action: deny in the PolicyLayer policy for create_vpc_subnet. 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_vpc_subnet? +

create_vpc_subnet is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
