Restore OPNsense configuration via SSH

How to control ssh_restore_config ↓

AI agents use ssh_restore_config to create or update resources in OPNSense MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OPNSense MCP Server environment.

Medium Risk

This tool restores OPNsense firewall configuration, which modifies network security settings reversibly (a backup can be restored again). While restoration could disrupt network operations if an incorrect config is restored, it is not irreversible (another restore could fix it) and does not permanently delete data, so it is Write rather than Destructive.

From the tool's definition Tool name 'ssh_restore_config' and description 'Restore OPNsense configuration via SSH' indicate the tool restores (reverts/overwrites) firewall configuration state. Restoration is a write operation that modifies system configuration.

Documented attack patterns abuse exactly the kind of access ssh_restore_config gives an agent:

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 ssh_restore_config:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh_restore_config": {
      "limits": [
        {
          "counter": "ssh_restore_config_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

ssh_restore_config stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

What does the ssh_restore_config tool do? +

Restore OPNsense configuration via SSH. It is categorised as a Write tool in the OPNSense MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on ssh_restore_config? +

Register the OPNSense MCP Server MCP server in PolicyLayer and add a rule for ssh_restore_config: 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 OPNSense MCP Server. Nothing to install.

What risk level is ssh_restore_config? +

ssh_restore_config is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit ssh_restore_config? +

Yes. Add a rate_limit block to the ssh_restore_config 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.

How do I block ssh_restore_config completely? +

Set action: deny in the PolicyLayer policy for ssh_restore_config. 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.

What MCP server provides ssh_restore_config? +

ssh_restore_config is provided by the OPNSense MCP Server MCP server (vespo92/opnsensemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every OPNSense MCP Server tool call.
