login_jd · Parcel Pilot MCP: Risk & Policy

WHAT IT DOES

What login_jd does on Parcel Pilot MCP

AI agents invoke login_jd 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_jd needs a policy

This tool launches a browser session and navigates to an external login page, constituting execution of a browser action with external side effects. It is not merely reading data — it opens a persistent browser session that could be reused for further actions. Severity is medium because it initiates authentication to a third-party platform (JD), which could expose credentials or session tokens if misused.
