AI agents call list_internet_service_groups to retrieve information from Fortimanager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a query/list operation to retrieve internet service group data from FortiManager. This is a read-only action with no side effects, no code execution, no data modification, and no destructive capability. The blast radius of misuse is minimal—an agent could retrieve configuration data but cannot modify, execute, or delete anything.
From the tool's definition Tool name 'list_internet_service_groups' and description 'List internet service groups' indicate a retrieval operation with no modification or execution.

PolicyLayer is an MCP gateway — it sits between your AI agents and Fortimanager, and nothing reaches the server without passing your rules. This is the rule we recommend for list_internet_service_groups:
{
"version": "1",
"default": "deny",
"tools": {
"list_internet_service_groups": {}
}
}list_internet_service_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List internet service groups. It is categorised as a Read tool in the Fortimanager MCP Server, which means it retrieves data without modifying state.
Register the Fortimanager MCP server in PolicyLayer and add a rule for list_internet_service_groups: 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 Fortimanager. Nothing to install.
list_internet_service_groups 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 list_internet_service_groups 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 list_internet_service_groups. 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.
list_internet_service_groups is provided by the Fortimanager MCP server (jmpijll/fortimanager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fortimanager, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
