Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_interfaces safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OPNsense MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_interfaces, this is the rule to start with:

get_interfaces Allowed

get_interfaces is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect OPNsense MCP Server, apply this rule, and every get_interfaces call is checked against it from then on.
