Get session statistics for a specific device.
AI agents call get_session_statistics 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 and queries session statistics from a device without creating, modifying, deleting, executing code, or moving money. It is a read-only operation with minimal blast radius if misused by an AI agent—the worst outcome would be unauthorized viewing of session data, which is less severe than Write, Execute, or Destructive actions.
From the tool's definition Tool name 'get_session_statistics' and description 'Get session statistics for a specific device' indicate a retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access get_session_statistics 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_session_statistics:
{
"version": "1",
"default": "deny",
"tools": {
"get_session_statistics": {}
}
}get_session_statistics 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 session statistics for a specific device. 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_session_statistics: 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_session_statistics 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_session_statistics 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_session_statistics. 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_session_statistics 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.
