AI agents call user_group_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 user group data from FortiOS without creating, modifying, or deleting any resources. The 'list' operation is a standard read-only query. The blast radius is minimal—exposing the list of user groups is a low-risk information disclosure that does not enable further privileged actions by itself.
From the tool's definition Tool name 'user_group_list' and description 'List all user groups' indicate a query/retrieval operation with no modification or side effects.

Documented attack patterns abuse exactly the kind of access user_group_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 user_group_list:
{
"version": "1",
"default": "deny",
"tools": {
"user_group_list": {}
}
}user_group_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.
List all user groups. 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 user_group_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.
user_group_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 user_group_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 user_group_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.
user_group_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.
