Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 35 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:** 3.31.2 - **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. The source supports an automatic, package-owned persistence mechanism but not a concrete malicious payload or credential-exfiltration attack. This warrants a warning for persistence risk rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-27T22:31:18.478Z - **Finished:** 2026-09-27T22:32:24.911Z - **Download time:** 1764 ms - **Static scan time:** 3590 ms - **AI review time:** 61077 ms - **Total time:** 66433 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:** No confirmed malicious attack was identified. The package nevertheless creates and starts a persistent per-user macOS service during npm postinstall. - **Trigger:** Installing or upgrading the package runs postinstall; the service setup applies on macOS unless disabled by its sentinel. - **Impact:** The package can remain running and restart automatically after installation, expanding its lifecycle impact beyond an explicit command invocation. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T22:32:24.911Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script writes a LaunchAgent configured to launch the package's serve-http command with RunAtLoad and KeepAlive. - **Rationale:** The source supports an automatic, package-owned persistence mechanism but not a concrete malicious payload or credential-exfiltration attack. This warrants a warning for persistence risk rather than a publication block. - **Files touched:** scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, package.json - **Network endpoints:** https://api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs two control scripts automatically through its postinstall hook., On macOS, the postinstall script writes a per-user LaunchAgent plist and bootstraps it., The generated service invokes the package launcher with serve-http and requests startup persistence., The app updater contacts the package release repository and requires a sibling checksum asset before update., The inspected agent-related bundle location only defines client configuration home paths; no write was found in that excerpt. - **Evidence against:** No evidence of credential collection or export was found in the inspected paths., The updater uses the package's release API path and checks for a checksum asset. ## Affected versions and remediation This report applies to trace-mcp@3.31.2. - Review the evidence and your use of trace-mcp@3.31.2 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. ## Public findings ### 1.
