mikrotik_flush_route_cache · MikroTik MCP: Risk & Policy

WHAT IT DOES

What mikrotik_flush_route_cache does on MikroTik MCP

AI agents invoke mikrotik_flush_route_cache to trigger actions in MikroTik MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why mikrotik_flush_route_cache needs a policy

Flushing a route cache is an operational action that clears cached routing information, forcing the router to recompute routes. This is not a simple read, nor does it permanently delete configuration data (the cache is transient and will be repopulated), but it does trigger an external operation on the network device that can momentarily disrupt routing decisions.
