Why opn_gateway_status needs a policy

This tool retrieves current status information about gateways and their health checks. It performs a query operation with no side effects, no data modification, and no code execution. The 'Get' verb clearly indicates a read operation. This is low severity because misuse would only expose monitoring data without affecting firewall configuration or operations.

From the tool's definition Tool name 'opn_gateway_status' and description 'Get gateway status including dpinger health checks' indicate a read-only retrieval of gateway and health check information with no modification, deletion, or execution capabilities.

POLICY

How to control opn_gateway_status

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 opn_gateway_status:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "opn_gateway_status": {}
  }
}

opn_gateway_status is read-only, so it stays allowed — but 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.
