WHAT IT DOES

What mikrotik_move_nat_rule does on MikroTik Cursor MCP

AI agents use mikrotik_move_nat_rule to create or update resources in MikroTik Cursor MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MikroTik Cursor MCP environment.

WHY IT NEEDS A POLICY

Why mikrotik_move_nat_rule needs a policy

Moving a NAT rule changes the order of packet processing in MikroTik's firewall chain, which modifies network behavior and routing. This is a reversible configuration change (the rule can be moved back), so it qualifies as Write rather than Destructive. However, reordering NAT rules can have significant side effects on network traffic flow and security posture if misapplied by an agent, justifying medium severity.

From the tool's definition Tool name 'mikrotik_move_nat_rule' and description 'Moves a NAT rule to a different position in the chain' indicate reordering/modification of firewall configuration without deletion.
