AI Security Review
scanned 24d ago · by lpm-firewall-aiSource inspection found a consent-gated install telemetry ping and a locally launched MCP server. No source evidence established credential theft, unauthorized mutation, or another attack surface.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package runs its postinstall hook; the hook sends only when its consent and environment guards pass.
Impact
No concrete attack impact was established; the observed behavior is consent-gated install telemetry.
Mechanism
The hook reads the Extenshi configuration and posts package version, runtime platform details, and an anonymous identifier to the telemetry host.
AI rationale
Source inspection found a consent-gated install telemetry ping and a locally launched MCP server. No source evidence established credential theft, unauthorized mutation, or another attack surface.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes the server through dist/index.js and runs scripts/postinstall.cjs during installation.
- The postinstall hook exits unless telemetry consent is recorded as true; it also honors opt-out and CI guards.
- The hook sends install metadata and an anonymous identifier to the configured telemetry host; it does not read or transmit an API session credential.
- dist/development-guide.js contains developer documentation URLs and service descriptions, with no reviewer-directed instructions in the inspected excerpt.
- The runtime entrypoint loads configuration and initializes telemetry before registering MCP tools.
