## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 3.6.0
- **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 install-time persistence and update surface, but the inspected source does not establish credential theft, third-party agent-control mutation, or other concrete malicious behavior. It warrants a warning as a first-party lifecycle risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-09-14T06:31:57.859Z

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 activates a postinstall hook that persists a trace-mcp launchd daemon on macOS. It can also download a same-vendor application release and replace an existing trace-mcp app.

- **Trigger:** npm installation; subsequent macOS app update and restart for the nested global reinstall.

- **Impact:** A background trace-mcp service can start automatically and package-controlled releases can refresh its application and CLI.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-14T06:33:23.169Z

### AI review details

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

- **Mechanism:** Install-time daemon persistence and remote application update.

- **Rationale:** This is a real install-time persistence and update surface, but the inspected source does not establish credential theft, third-party agent-control mutation, or other concrete malicious behavior. It warrants a warning as a first-party lifecycle risk.

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

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The package runs three scripts automatically in postinstall., The postinstall hook writes a per-user launcher configuration and executable shim., On macOS it creates a launchd job with RunAtLoad and KeepAlive, starting a persistent local daemon., The install hook fetches a release from GitHub and can replace an installed application; its updater can reinstall trace-mcp globally.

- **Evidence against:** No dependency on trace-mcp itself appears in package.json., The app update path requires an existing macOS app and checks a release checksum., No source evidence shows secret collection, exfiltration, or mutation of third-party AI-client settings during install.

## Affected versions and remediation

This report applies to trace-mcp@3.6.0.

- Review the evidence and your use of trace-mcp@3.6.0 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.
