AI agents call opn_ipsec_status to retrieve information from OPNsense MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Status queries are read-only operations that retrieve current state of IPsec connections on the OPNsense firewall. No data modification, deletion, or external execution occurs. Even if status information could inform policy decisions, the tool itself performs no side effects. Low severity reflects minimal blast radius from querying operational status.
From the tool's definition Tool name 'opn_ipsec_status' indicates a status query operation. The suffix '_status' conventionally retrieves system state information without modification. Description is empty, limiting precision.
Documented attack patterns abuse exactly the kind of access opn_ipsec_status 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 opn_ipsec_status:
{
"version": "1",
"default": "deny",
"tools": {
"opn_ipsec_status": {}
}
}opn_ipsec_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

opn_ipsec_status. It is categorised as a Read tool in the OPNsense MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OPNsense MCP Server MCP server in PolicyLayer and add a rule for opn_ipsec_status: 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.
opn_ipsec_status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the opn_ipsec_status 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.
Set action: deny in the PolicyLayer policy for opn_ipsec_status. 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.
opn_ipsec_status is provided by the OPNsense MCP Server MCP server (lucamarien/opnsense-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OPNsense MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
