Why zabbix_get_usergroups needs a policy

The tool retrieves and queries user group information from Zabbix. It has no side effects, does not execute operations, does not modify or delete data, and does not involve financial transactions. This is a straightforward read operation with minimal blast radius if misused by an AI agent — at worst, it would leak non-sensitive organizational structure information about user groups.

From the tool's definition Tool name contains 'get_usergroups' and description states 'Get user groups from Zabbix with filtering and output options' — this is a retrieval operation with no modification or deletion of data.

How to control zabbix_get_usergroups

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "zabbix_get_usergroups": {}
  }
}

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

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