Installing the package runs code that creates a trace-mcp launcher and, on macOS, a persistent launchd service. It can also download and replace an existing matching desktop app, and its bundled updater can reinstall the package globally. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-28T15:07:56.402Z - **Finished:** 2026-08-28T15:09:20.167Z - **Download time:** 1010 ms - **Static scan time:** 3314 ms - **AI review time:** 79439 ms - **Total time:** 83765 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs code that creates a trace-mcp launcher and, on macOS, a persistent launchd service. It can also download and replace an existing matching desktop app, and its bundled updater can reinstall the package globally. - **Trigger:** npm installation; later restart of the installed desktop app for the recursive global install - **Impact:** A package install can create a continuously restarted local daemon, replace a desktop application, and trigger another lifecycle-enabled global installation. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, scripts/apply-pending-update.mjs, hooks/trace-mcp-launcher.cmd - **Review source:** ai\_review - **Reviewed:** 2026-08-28T15:09:20.167Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic lifecycle persistence and self-update chain - **Rationale:** The package has a concrete automatic persistence and update surface, including a lifecycle-enabled self-install path. The inspected source does not establish secret exfiltration, destructive project mutation, or a foreign AI-agent control-surface takeover, so warning is more proportionate than blocking. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/.trace-mcp/postinstall.log, .trace-mcp-pending.zip - **Network endpoints:** https://api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The install hook automatically runs three package scripts., On macOS it writes and bootstraps a persistent per-user launch agent., The generated service uses RunAtLoad and KeepAlive., Install-time code queries GitHub releases and downloads a desktop-app update., A bundled update helper can globally install another trace-mcp version and re-enable its postinstall., A Windows hook hides its PowerShell window while bypassing execution policy. - **Evidence against:** No credential or environment-secret collection and exfiltration was found in the inspected lifecycle scripts., The update flow checks a SHA-256 release asset and uses explicit executable paths rather than a shell., The app-update path requires macOS and an already installed matching app; the bundled agent plugins require explicit plugin installation., The code provides environment-variable opt-outs for postinstall and app auto-update. ## Public findings ### 1.
