pt_fix_plan · MCP Packet Tracer MCP: Risk & Policy

WHAT IT DOES

What pt_fix_plan does on MCP Packet Tracer

AI agents invoke pt_fix_plan to trigger actions in MCP Packet Tracer. 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
