Installing the package automatically creates trace-mcp launcher files and, on macOS, a persistent trace-mcp launchd service. A later GUI update can reinstall the package to match its application version. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 92.0% - **Started:** 2026-08-29T21:45:52.272Z - **Finished:** 2026-08-29T21:46:57.406Z - **Download time:** 769 ms - **Static scan time:** 3457 ms - **AI review time:** 60905 ms - **Total time:** 65134 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically creates trace-mcp launcher files and, on macOS, a persistent trace-mcp launchd service. A later GUI update can reinstall the package to match its application version. - **Trigger:** npm installation triggers postinstall; the running GUI application's update-and-restart path triggers the nested npm install. - **Impact:** It can persistently run the package's daemon and repeat its install lifecycle, but the inspected code does not establish data theft or foreign agent-control hijacking. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, scripts/apply-pending-update.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T21:46:57.406Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic first-party daemon setup and self-reinstallation. - **Rationale:** The package has an automatic persistent service setup and an automatic self-reinstallation path, creating a lifecycle risk. Source inspection found no concrete malicious payload or exfiltration behavior, so blocking is not justified. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/Applications/trace-mcp.app - **Network endpoints:** https://api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Its automatic postinstall runs a control-plane installer., On macOS, installation writes and bootstraps a persistent launchd daemon., A GUI-triggered updater runs npm to install trace-mcp again at a selected version. - **Evidence against:** The lifecycle code targets trace-mcp-owned paths and service names, not third-party agent configuration., The updater verifies downloaded application archives with SHA-256 before replacing the app., No source evidence shows credential harvesting, secret exfiltration, obfuscation, or foreign AI-agent configuration writes. ## Public findings ### 1.
