WHAT IT DOES

What create_volume does on Linode MCP Server

AI agents use create_volume 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_volume is rated Medium

The tool creates a new persistent storage volume in Linode, which is a reversible write operation. While it allocates cloud resources and incurs potential costs, it does not execute arbitrary code, delete data, or move money directly. The severity is medium because creating volumes consumes resources and could impact infrastructure costs, but the action is reversible (the volume can be deleted).

From the tool's definition Tool name is 'create_volume' and description states 'Create a new volume'. This is a create operation that adds a new resource to the user's Linode infrastructure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_volume 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_volume, this is the rule to start with:

create_volume Rate-limited

create_volume 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

What risk level is create_volume? +

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

Can I rate-limit create_volume? +

Yes. Add a rate_limit block to the create_volume 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_volume completely? +

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