Installing the package automatically creates package-owned launcher and daemon state, including a macOS launchd service. Running the package can also download and force-install a newer release and emit limited usage telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-28T20:46:59.684Z - **Finished:** 2026-08-28T20:48:12.336Z - **Download time:** 1266 ms - **Static scan time:** 3400 ms - **AI review time:** 67984 ms - **Total time:** 72652 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically creates package-owned launcher and daemon state, including a macOS launchd service. Running the package can also download and force-install a newer release and emit limited usage telemetry. - **Trigger:** npm installation triggers postinstall; normal CLI or daemon startup triggers update checks and telemetry. - **Impact:** It can persist a local daemon, replace the associated app, globally reinstall itself, and disclose limited installation metadata. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, dist/cli.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T20:48:12.336Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Package-owned persistence with automatic self-update and usage telemetry. - **Rationale:** The package is not clean because it persists a service and automatically reinstalls its own latest release. The inspected source does not establish concrete malicious behavior under the stated policy, so this is a warning rather than a block. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/.trace-mcp/telemetry-state.json - **Network endpoints:** https://api.github.com/repos/${GITHUB\_REPO}/releases/latest, https://registry.npmjs.org/trace-mcp/latest, https://www.google-analytics.com/mp/collect ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The install hook automatically runs three scripts., The install hook writes a persistent launchd service that starts the package daemon., The install hook downloads and replaces an installed desktop app from release assets., Normal package startup can fetch the latest version and run a forced global install of the same package., Runtime telemetry sends an install identifier, version, platform, and Node major version to Google Analytics by default. - **Evidence against:** The persistence targets the package's own trace-mcp service rather than a foreign agent configuration., Claude hook changes are exposed through an explicit setup-hooks command., The app-update script verifies a downloaded archive against a sibling SHA-256 manifest before replacement., No source evidence showed secret harvesting or transmission of project file contents in the automatic lifecycle path. ## Public findings ### 1.
