AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package sends undisclosed runtime usage telemetry to its own service during free CLI runs, so it is suspicious under the telemetry rule. The reported fields are limited and the request can be disabled, with no evidence of credential or file exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A free CLI run in a TTY or MCP session, unless telemetry is opted out or CI is detected.
Impact
The vendor learns that the tool was used in a free run; the event does not include file contents or credentials.
Mechanism
Posts a minimal usage event to the package vendor’s endpoint.
AI rationale
The package sends undisclosed runtime usage telemetry to its own service during free CLI runs, so it is suspicious under the telemetry rule. The reported fields are limited and the request can be disabled, with no evidence of credential or file exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free CLI run automatically sends a `use` event to `getreadystack.com/api/ev`.
- That event contains only the package slug, CLI source, and a fixed `free` reason; no file contents or credentials are included.
- The event is suppressed by telemetry opt-out variables and in CI, and is sent only for a TTY or MCP session.
- The README describes the free CLI checks but does not disclose this usage reporting.
Evidence against
- The manifest defines a CLI entry point and no lifecycle scripts.
- License validation sends the user-provided or stored Readystack license key to Polar’s license-validation endpoint, consistent with the paid feature.
- The rules feed uses the license key with Readystack’s own service; feed data is parsed as JSON rules.
- The usage event carries limited tool-use metadata rather than host, user, project, or file data.
