login_cainiao · Parcel Pilot MCP: Risk & Policy

WHAT IT DOES

What login_cainiao does on Parcel Pilot MCP

AI agents invoke login_cainiao to trigger actions in Parcel Pilot 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 login_cainiao needs a policy

This tool launches a browser session (an external operation with side effects) to open the Cainiao platform and capture a screenshot. It is not a simple read — it actively starts a persistent browser process and triggers an authentication flow. This falls under Execute as it runs browser actions whose effects depend on the external service interaction.
