Get system resource usage including CPU, memory, and disk statistics.
AI agents call get_system_resource_usage 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.
This tool retrieves system resource metrics (CPU, memory, disk) from FortiManager without modifying any configuration or state. It is a pure read operation with no destructive, executable, or financial implications. The potential blast radius of misuse is minimal—an agent could only gather system information, which poses minimal risk.
From the tool's definition Tool name is 'get_system_resource_usage' and description states it 'Get[s] system resource usage including CPU, memory, and disk statistics.' The verb 'get' and the read-only nature of querying statistics indicate no data modification or side effects.
Documented attack patterns abuse exactly the kind of access get_system_resource_usage 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_system_resource_usage:
{
"version": "1",
"default": "deny",
"tools": {
"get_system_resource_usage": {}
}
}get_system_resource_usage 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 system resource usage including CPU, memory, and disk statistics. 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_system_resource_usage: 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_system_resource_usage 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_system_resource_usage 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_system_resource_usage. 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_system_resource_usage 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.
Free to start. No card required.
