routing_fix_all

THE RISK

High Risk

This tool automatically modifies firewall/routing configuration to fix inter-VLAN routing issues. It triggers operational changes to network routing rules and firewall settings, which is an Execute-level action. The blast radius is high because misconfigured routing changes on a firewall could disrupt network connectivity across VLANs or expose network segments.

From the tool's definition "Automatically fix all detected inter-VLAN routing issues"

HOW TO CONTROL ROUTING_FIX_ALL

PolicyLayer is an MCP gateway — it sits between your AI agents and OPNSense MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for routing_fix_all:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "routing_fix_all": {
      "limits": [
        {
          "counter": "routing_fix_all_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

routing_fix_all stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register OPNSense MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
