Why zabbix_create_script needs a policy

Creating a script in Zabbix defines executable code that can later be triggered on remote hosts or via automated actions. While the act of creation is a Write operation, Zabbix scripts are specifically execution artifacts (shell commands, IPMI commands, webhook scripts) intended to be run on infrastructure.

From the tool's definition 'Create a new script in Zabbix' — scripts in Zabbix are executable commands/shell scripts that can be run against monitored hosts

POLICY

How to control zabbix_create_script

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_create_script:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "zabbix_create_script": {
      "limits": [
        {
          "counter": "zabbix_create_script_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

zabbix_create_script stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.

FAQ

Questions about zabbix_create_script

What does the zabbix_create_script tool do? +

Create a new script in Zabbix. It is categorised as a Execute tool in the Zabbix MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on zabbix_create_script? +

Register the Zabbix MCP Server MCP server in PolicyLayer and add a rule for zabbix_create_script: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Zabbix MCP Server. Nothing to install.

What risk level is zabbix_create_script? +

zabbix_create_script is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit zabbix_create_script? +

Yes. Add a rate_limit block to the zabbix_create_script rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block zabbix_create_script completely? +

Set action: deny in the PolicyLayer policy for zabbix_create_script. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides zabbix_create_script? +

zabbix_create_script is provided by the Zabbix MCP Server MCP server (leroylim/zabbix-mcp-server-nodejs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Zabbix MCP Server tool call.

Start from Zabbix MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
