Why monitor_firewall_session_close needs a policy

Closing firewall sessions is not a read or write operation — it actively terminates live network connections. This cannot be undone (the session is gone and must be re-established by the client). The description is empty, so confidence is reduced, but the name strongly implies destructive/irreversible session termination with potentially high blast radius (could disrupt active traffic).

From the tool's definition Tool name: monitor_firewall_session_close — 'close' applied to firewall sessions implies terminating active network sessions, which is an irreversible action (sessions must be re-established).

POLICY

How to control monitor_firewall_session_close

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 monitor_firewall_session_close:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "monitor_firewall_session_close"
  ]
}

monitor_firewall_session_close disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
