AI Security Review

scanned 4d ago · by lpm-firewall-ai

Source inspection found an automatic postinstall chain, but its inspected behavior supports native preflight, app updating, and package launcher maintenance. The scanner's source-similarity labels did not establish attack behavior in the flagged scripts or inspected agent-related locations.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

npm install triggers the package's postinstall scripts; benchmark and fixture scripts require explicit invocation.

Impact

No confirmed harmful effect or attacker-controlled data transfer was established.

Mechanism

The inspected installer code maintains the trace-mcp launcher and app. Agent path constants and the flagged benchmark locations do not establish automatic agent configuration changes or credential transfers.

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json runs native preflight, app update, and control-plane setup during postinstall; its other lifecycle hooks are build or Git-hook setup.
The control-plane installer documents opt-outs and skips ephemeral installs; its writes maintain the package launcher and daemon configuration.
The app updater uses the GitHub API by default, and preflight runs only on macOS.
Agent configuration paths in the inspected bundles are definitions; the flagged script locations read session logs or compare benchmark text.
Flagged high-similarity scripts describe fixture capture, benchmarks, release checks, and documentation generation.
