AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package performs undisclosed runtime telemetry during ordinary CLI use, which warrants a warning under the review rules. The flagged licence-key traffic is consistent with validation by the package’s own service and Polar, and the telemetry payloads contain only limited event fields.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A free CLI run, or an interactive/MCP run with a missing or invalid licence key.
Impact
The vendor can count package use and paywall events; no sensitive user data is present in the observed payloads.
Mechanism
POSTs tool slug, source, and event reason to `getreadystack.com/api/ev`; terminal and MCP session gates and opt-out environment variables apply.
AI rationale
The package performs undisclosed runtime telemetry during ordinary CLI use, which warrants a warning under the review rules. The flagged licence-key traffic is consistent with validation by the package’s own service and Polar, and the telemetry payloads contain only limited event fields.

Decision evidence
public snapshotAI called this Suspicious at 95.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free CLI run automatically sends a `use` event with the tool slug, source, and `free` reason to `getreadystack.com/api/ev`.
- Paywall events also send the tool slug, source, and reason to that endpoint when a key is missing or invalid; the README does not disclose these analytics pings.
Evidence against
- The analytics payloads contain no credentials, file contents, hostnames, or user identifiers.
- The pings are limited to interactive terminal or MCP sessions and can be disabled with `DO_NOT_TRACK=1` or `READYSTACK_NO_TELEMETRY`.
- Licence validation sends the supplied licence key to Readystack and Polar, the services used for licence checks.
