AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package’s licensing and rule-feed traffic appears purpose-related, and the scanner’s credential-exfiltration claim is not supported by the source. However, paid-use failures trigger undisclosed runtime telemetry to the vendor, so this warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A paid CLI or MCP operation encounters a missing or invalid license key in an interactive terminal or MCP session.
Impact
The vendor learns that this package encountered a license paywall and whether it ran through the CLI or MCP.
Mechanism
The package sends the event type, package slug, session source and reason to the vendor endpoint; two environment-variable settings suppress it.
AI rationale
The package’s licensing and rule-feed traffic appears purpose-related, and the scanner’s credential-exfiltration claim is not supported by the source. However, paid-use failures trigger undisclosed runtime telemetry to the vendor, so this warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- When a license key is missing or rejected, the code calls a paywall event sender; it sends only from an interactive terminal or MCP session unless a telemetry opt-out is set.
- The event includes the package slug, CLI/MCP source and a reason, and is POSTed to getreadystack.com/api/ev.
- The README describes the paid features and license setup but does not disclose this runtime event.
Evidence against
- The event does not include paths, file contents, environment values or other user credentials.
- Telemetry is limited to interactive terminal or MCP sessions and can be disabled with DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY.
- License keys are sent to Polar for validation and to getreadystack.com for the package’s license feed, which are license-related uses.
