AI agents call get_policy_usage_stats 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 retrieves policy usage statistics from FortiManager without performing any modifications, deletions, or external operations. The 'get_' prefix is a strong indicator of a read-only operation. Empty description lowers confidence slightly, but the naming pattern is unambiguous. Read operations present minimal risk as they have no side effects on system state.
From the tool's definition Tool name 'get_policy_usage_stats' uses the 'get' prefix, which typically indicates a read operation that retrieves usage statistics without modifying data. The tool description is empty, but the naming convention strongly suggests a query operation.
Documented attack patterns abuse exactly the kind of access get_policy_usage_stats gives an agent:
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 get_policy_usage_stats:
{
"version": "1",
"default": "deny",
"tools": {
"get_policy_usage_stats": {}
}
}get_policy_usage_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_policy_usage_stats. 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 get_policy_usage_stats: 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.
get_policy_usage_stats 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 get_policy_usage_stats 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 get_policy_usage_stats. 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.
get_policy_usage_stats 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.
