It performs no side effects, makes no changes to infrastructure or data, and poses minimal security risk if misused by an AI agent. The only information exposed is metadata about subscription offerings, which is typically non-sensitive product information.

From the tool's definition Tool name is 'list_longview_subscriptions' and description states it 'Get a list of all Longview subscription plans' — a pure retrieval operation with no modification, deletion, or execution capability.

POLICY

How to control list_longview_subscriptions

PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_longview_subscriptions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_longview_subscriptions": {}
  }
}

list_longview_subscriptions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Linode MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
