THE RISK

Low Risk

Why list_service_alert_definitions needs a policy

This tool retrieves metadata about alert configurations for a service, analogous to querying or viewing existing settings. It produces no side effects, does not modify infrastructure, and poses minimal risk even if misused by an AI agent, as it only exposes read-only alert definition data.

From the tool's definition Tool name contains 'list' and description states it 'List alert definitions' — a retrieval operation with no modification, deletion, or execution of code/commands. Returns information about existing alert thresholds.

POLICY

How to control list_service_alert_definitions

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_service_alert_definitions:

policy.json

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

list_service_alert_definitions 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.
