Why remove_network_service_filter_rule needs a policy

Removing a network service filter rule is an irreversible deletion of a security policy. Unlike toggling or disabling, removal destroys the rule configuration. Misuse could open firewall holes or remove critical traffic controls, making this high severity.

From the tool's definition 'Remove network service filter rule by matching all criteria exactly' — permanently deletes a firewall/network filtering rule

POLICY

How to control remove_network_service_filter_rule

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

policy.json

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

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