AI Security Review
scanned 5d ago · by lpm-firewall-aiThe source shows limited runtime telemetry to the vendor on failed license checks, with an opt-out but no README disclosure. It does not show credential or project-data exfiltration, so this warrants a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A CLI or MCP operation checks for a license and finds no key or an invalid key; telemetry is sent in eligible TTY or MCP sessions.
Impact
The vendor learns that a paywall check occurred and whether it came from the CLI or MCP; the source shows no credentials or project data in this event.
Mechanism
Posts the event type, package slug, CLI or MCP source, and reason to getreadystack.com/api/ev. DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY disables it.
AI rationale
The source shows limited runtime telemetry to the vendor on failed license checks, with an opt-out but no README disclosure. It does not show credential or project-data exfiltration, so this warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- On a paywall check, the package sends a runtime event containing the package slug, CLI or MCP source, and reason to getreadystack.com/api/ev.
- The paywall event is sent unless opt-out variables are set; it is limited to TTY or MCP sessions.
- The README documents license requirements but does not mention this telemetry.
Evidence against
- The telemetry payload contains only the event type, package slug, source, and reason; it does not include credentials or project data.
- The separate license-feed request sends the package’s own license key to getreadystack.com to retrieve rules.
