AI agents call ssh_show_routing 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.
This tool only reads and displays routing information; it has no side effects, does not modify network configuration, and does not execute arbitrary commands. It is a straightforward informational query similar to running 'route' or 'netstat' commands for viewing purposes only.
From the tool's definition Tool name 'ssh_show_routing' with description 'Show routing table via SSH' indicates a query operation that retrieves and displays the existing routing table without modification.
Documented attack patterns abuse exactly the kind of access ssh_show_routing 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_show_routing:
{
"version": "1",
"default": "deny",
"tools": {
"ssh_show_routing": {}
}
}ssh_show_routing is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show routing table via SSH. 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 ssh_show_routing: 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.
ssh_show_routing 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 ssh_show_routing 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 ssh_show_routing. 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.
ssh_show_routing 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.
