AI agents call firewall_policy_list to retrieve information from FortiOS 7 6 X MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates firewall policies without modifying, deleting, or executing actions. The lack of description is noted, but the naming convention and context from sibling tools provide sufficient evidence. Severity is low because listing policies is informational only, though it could expose security configuration details to an unauthorized agent.
From the tool's definition Tool name 'firewall_policy_list' indicates retrieval/enumeration of firewall policies. The '_list' suffix conventionally denotes query operations with no side effects.
Documented attack patterns abuse exactly the kind of access firewall_policy_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FortiOS 7 6 X MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for firewall_policy_list:
{
"version": "1",
"default": "deny",
"tools": {
"firewall_policy_list": {}
}
}firewall_policy_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
