Why zabbix_delete_media_types needs a policy

This tool irreversibly removes media type configurations from Zabbix. Deleting media types could break alerting infrastructure by removing notification channels (email, SMS, webhooks, etc.) that alert rules depend on. This is an unrecoverable action that would require manual reconfiguration to restore. While not as critical as deleting hosts or events, it is still destructive infrastructure configuration removal.

From the tool's definition Tool name explicitly uses 'delete' and description states 'Delete media types from Zabbix'. Media types define notification channels and cannot be easily recreated without reconfiguration.

POLICY

How to control zabbix_delete_media_types

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_delete_media_types:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "zabbix_delete_media_types"
  ]
}

zabbix_delete_media_types disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
