Package Track

Security checks across malware telemetry and agentic risk

Overview

This appears to be a courier-tracking skill that discloses its external API use, with privacy considerations around tracking numbers and optional phone verification data.

Install only if you are comfortable sending package tracking numbers, carrier identifiers, and for some carriers limited verification data such as the last four digits of a phone number to Kdniao. Confirm the skill or platform clearly exposes its network/API requirement before use.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill advertises and relies on outbound network access to a third-party courier API, but does not declare permissions accordingly. This creates a transparency and policy-enforcement gap: users or the hosting platform may invoke the skill without realizing it can transmit package identifiers and potentially customer verification data off-box.
