Return packages delivered today in the configured timezone.
AI agents call get_delivered_today to retrieve information from Parcel Pilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries personal package tracking information and returns a filtered view of delivered packages. It is read-only with no capability to modify, delete, or trigger external operations. The blast radius of misuse is minimal—an attacker could learn delivery history but cannot intercept packages, modify orders, or cause financial harm.
From the tool's definition Tool description states 'Return packages delivered today' — a retrieval operation with no modification, deletion, or execution of external actions. The verb 'Return' indicates querying existing data without side effects.
