Why arr_get_system_status needs a policy

This tool retrieves system status information from media automation services (Sonarr, Radarr, Prowlarr, etc.) without modifying, executing commands against external systems, or deleting data. It is purely informational querying, fitting the Read category. Severity is low because status information alone poses minimal risk even if misused by an agent.

From the tool's definition Tool name is 'arr_get_system_status' and description states 'Get system status for all configured arr services' — uses 'Get' verb indicating data retrieval with no modification or deletion.

POLICY

How to control arr_get_system_status

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

policy.json

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

arr_get_system_status 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 Arr Suite 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.
