Why zabbix_login needs a policy

This tool performs authentication and session establishment rather than reading, writing, executing, or destroying data. It obtains a session token that enables subsequent API calls. While not destructive or financial, misuse (e.g., credential theft or session hijacking) carries medium severity since the resulting token grants access to a broad monitoring infrastructure with 90+ tools.

From the tool's definition Authenticate with Zabbix server and obtain session token. Required before using other tools.

POLICY

How to control zabbix_login

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_login:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "zabbix_login": {
      "limits": [
        {
          "counter": "zabbix_login_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

zabbix_login gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Zabbix 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.
