Why netdata_alarms needs a policy

This tool retrieves alarm status information from Netdata monitoring infrastructure. It performs a read-only query operation with no side effects—it does not modify alarms, execute commands, or trigger external operations. The blast radius of misuse is minimal: an AI agent could only view alarm states, not alter system configurations or trigger destructive actions.

From the tool's definition Tool name 'netdata_alarms' combined with description 'List Netdata alarms' indicates a retrieval operation. The phrase 'returns only raised alarms' confirms it queries and retrieves monitoring/alarm data without modification or execution.

POLICY

How to control netdata_alarms

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

policy.json

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

netdata_alarms 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 Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
