## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 24 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Persistence
- **Selected version:** 3.22.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

This is a real, automatic lifecycle attack surface rather than a scanner-only signal. The behavior is package-aligned but still dangerous because it persists a daemon and replaces executable application code from a mutable remote release channel.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-09-07T09:53:21.427Z
- **Finished:** 2026-09-07T09:54:29.407Z
- **Download time:** 2028 ms
- **Static scan time:** 6061 ms
- **AI review time:** 59889 ms
- **Total time:** 67980 ms

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically creates and starts a persistent per-user macOS daemon. The same lifecycle hook downloads a latest-release archive and can replace installed trace-mcp application bundles.

- **Trigger:** npm postinstall, including a global installation or upgrade

- **Impact:** A package installation can start software on login and replace local application code with a network-fetched release outside the npm artifact.

- **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-07T09:54:29.407Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Lifecycle-driven persistence and remote application replacement

- **Rationale:** This is a real, automatic lifecycle attack surface rather than a scanner-only signal. The behavior is package-aligned but still dangerous because it persists a daemon and replaces executable application code from a mutable remote release channel.

- **Files touched:** ~/.trace/launcher.env, ~/.trace/bin/trace, ~/Library/LaunchAgents/com.trace-mcp.server.plist, trace-mcp.app

- **Network endpoints:** api.github.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The automatic postinstall chain runs two scripts that alter user-level state., On macOS, postinstall writes and bootstraps a persistent LaunchAgent with RunAtLoad and KeepAlive., The installer fetches a latest GitHub release and replaces installed application bundles with its downloaded archive., The checksum is downloaded from the same release source as the archive, so it does not establish an independent trust boundary.

- **Evidence against:** The remote update path is limited to macOS and targets trace-mcp application bundles., The code has opt-out environment variables and checks a daemon-disabled marker., No credential harvesting or secret exfiltration was found in the inspected lifecycle scripts.

## Affected versions and remediation

This report applies to trace-mcp@3.22.0.

- Review the evidence and your use of trace-mcp@3.22.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
