Get the ARP table (IP-to-MAC address mappings).
AI agents call monitor_network_arp_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 network ARP table information (IP-to-MAC address mappings) without any capability to modify, delete, or execute operations. It is a read-only query of existing network state data. The blast radius of misuse is minimal—an attacker could gain visibility into network topology but cannot alter configurations, execute commands, or cause damage.
From the tool's definition Tool name contains 'monitor' and 'list', and description states 'Get the ARP table'. The word 'Get' and 'list' indicate data retrieval with no modification capability.
Documented attack patterns abuse exactly the kind of access monitor_network_arp_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 monitor_network_arp_list:
{
"version": "1",
"default": "deny",
"tools": {
"monitor_network_arp_list": {}
}
}monitor_network_arp_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the ARP table (IP-to-MAC address mappings). It is categorised as a Read tool in the FortiOS 7 6 X MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FortiOS 7 6 X MCP Server MCP server in PolicyLayer and add a rule for monitor_network_arp_list: 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 FortiOS 7 6 X MCP Server. Nothing to install.
monitor_network_arp_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the monitor_network_arp_list 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.
Set action: deny in the PolicyLayer policy for monitor_network_arp_list. 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.
monitor_network_arp_list is provided by the FortiOS 7 6 X MCP Server MCP server (paoloamato2/fortinet-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FortiOS 7 6 X MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
