mikrotik_move_nat_rule · MikroTik MCP: Risk & Policy

WHAT IT DOES

What mikrotik_move_nat_rule does on MikroTik MCP

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

WHY IT NEEDS A POLICY

Why mikrotik_move_nat_rule needs a policy

Moving a NAT rule reorders firewall rules, changing network packet routing behavior. This is a write operation (modifies configuration state) rather than destructive (the rule itself is not deleted, just repositioned). However, it carries medium severity because incorrect NAT rule ordering can disrupt network traffic flows, affect security posture, and impact multiple connected systems.

From the tool's definition Tool name contains 'move' and description states it 'Moves a NAT rule to a different position in the chain' — this modifies the order/configuration of firewall NAT rules, which is a reversible change to network policy.
