WHAT IT DOES

What mikrotik_add_blackhole_route does on MikroTik Cursor MCP

AI agents use mikrotik_add_blackhole_route 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.

RISK

Why mikrotik_add_blackhole_route is rated Medium

This tool creates a new routing rule that will affect network traffic flow. It is reversible (the route can be deleted), making it Write rather than Destructive. However, severity is high because misconfigured blackhole routes can disrupt network connectivity and cause service outages affecting multiple users/systems.

From the tool's definition Tool name explicitly states 'add' (creates/modifies), and description confirms it 'Adds a blackhole route'. Blackhole routes are network configuration changes that redirect traffic to a null destination, modifying router behavior.
