THE RISK

Low Risk

Why get_nagios_process_info needs a policy

This tool queries monitoring system state and returns status information. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal — an attacker gains visibility into Nagios process health but cannot alter configuration, trigger actions, or affect monitored systems. Classification as Read is appropriate.

From the tool's definition Retrieves the Nagios Core program status from `statusjson.cgi` — the verb 'Retrieves' and the read-only endpoint `statusjson.cgi` indicate data querying with no side effects.

POLICY

How to control get_nagios_process_info

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

policy.json

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

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