AI agents use firewall_vip_create to create or update resources in FortiOS 7 6 X MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FortiOS 7 6 X MCP Server environment.
This tool creates firewall VIP objects, which is a reversible write operation to network infrastructure. While the description is empty, the tool name and context (FortiOS firewall management) clearly indicate it modifies firewall configuration. VIP creation has high blast radius due to impact on network traffic routing, but it is reversible (can be deleted), so it is Write not Destructive.
From the tool's definition Tool name 'firewall_vip_create' contains 'create', which creates a firewall VIP (Virtual IP) configuration. On a FortiOS device, VIPs are critical network configurations that control traffic routing and NAT behavior.
Documented attack patterns abuse exactly the kind of access firewall_vip_create 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_vip_create:
{
"version": "1",
"default": "deny",
"tools": {
"firewall_vip_create": {
"limits": [
{
"counter": "firewall_vip_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}firewall_vip_create stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

firewall_vip_create. It is categorised as a Write tool in the FortiOS 7 6 X MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the FortiOS 7 6 X MCP Server MCP server in PolicyLayer and add a rule for firewall_vip_create: 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.
firewall_vip_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the firewall_vip_create 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 firewall_vip_create. 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.
firewall_vip_create 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.
