Lists all port forwarding rules (dstnat dst-nat rules)
AI agents call mikrotik_list_port_forwards to retrieve information from MikroTik Cursor MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing port forwarding configuration from the MikroTik router and returns information. It does not create, modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker would only gain visibility into the current NAT rules, which while informative about network topology, does not directly compromise systems or enable unauthorized actions without additional tools.
From the tool's definition The tool name contains 'list' and the description explicitly states it 'Lists all port forwarding rules'. This is a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists all port forwarding rules (dstnat dst-nat rules). It is categorised as a Read tool in the MikroTik Cursor MCP MCP Server, which means it retrieves data without modifying state.
Register the MikroTik Cursor MCP server in PolicyLayer and add a rule for mikrotik_list_port_forwards: 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 MikroTik Cursor MCP. Nothing to install.
mikrotik_list_port_forwards 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 mikrotik_list_port_forwards 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 mikrotik_list_port_forwards. 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.
mikrotik_list_port_forwards is provided by the MikroTik Cursor MCP server (kevinpez/mikrotik-cursor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
