Installing the package automatically creates package-owned launcher files and, on macOS, a persistent launchd daemon. It also performs a package-aligned desktop-app update from GitHub release assets. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-29T11:42:50.336Z - **Finished:** 2026-08-29T11:43:53.170Z - **Download time:** 758 ms - **Static scan time:** 3415 ms - **AI review time:** 58659 ms - **Total time:** 62834 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically creates package-owned launcher files and, on macOS, a persistent launchd daemon. It also performs a package-aligned desktop-app update from GitHub release assets. - **Trigger:** npm postinstall; the desktop application's pending-update path for the nested npm refresh. - **Impact:** A global install can start or refresh a persistent local service and replace the package's desktop application without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, scripts/apply-pending-update.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T11:43:53.170Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time daemon persistence and remote application update. - **Rationale:** The package has real automatic persistence and remote-update behavior that merits a warning. Source inspection found no concrete malicious payload, exfiltration, foreign AI-agent control-surface mutation, or manifest-declared lifecycle self-dependency. - **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:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The automatic postinstall chain runs a control-plane installer., On macOS, installation writes and bootstraps a persistent user launch agent that starts the package daemon., The postinstall updater downloads a release archive and replaces an existing desktop application., A bundled runtime updater can run npm install for another trace-mcp version. - **Evidence against:** package.json has no dependency on trace-mcp itself., AI-client configuration and hook installation are exposed through the explicit trace-mcp init command., The inspected lifecycle scripts contain no credential collection or secret exfiltration., The updater checks a SHA-256 release checksum and keeps the update within the package's own application paths. ## Public findings ### 1.
