It can also update an existing trace-mcp desktop app. - **Trigger:** npm install, including postinstall execution - **Impact:** A package service can continue running after installation; the updater can replace the package's existing desktop app. - **Evidence paths:** package.json, scripts/preflight-native.mjs, scripts/postinstall-app.mjs, scripts/postinstall-control-plane.mjs, .claude-plugin/hooks/hooks.json, .codex-plugin/hooks/hooks.json, hooks/trace-mcp-guard.sh, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T14:55:54.054Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Package-owned launcher installation, launchd bootstrap, and guarded GitHub app update - **Rationale:** The package has a real install-time persistence and update surface, so it warrants a warning. The reviewed source aligns that behavior to trace-mcp itself and does not establish malicious intent or a concrete theft or hijacking chain. - **Files touched:** scripts/preflight-native.mjs, scripts/postinstall-app.mjs, scripts/postinstall-control-plane.mjs, hooks/trace-mcp-launcher.sh, ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist - **Network endpoints:** https://api.github.com/repos/${GITHUB\_REPO}/releases/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Postinstall runs three package scripts automatically., The control-plane postinstall writes a user launcher and can create a persistent macOS launch agent., The launch agent uses RunAtLoad and KeepAlive, so it starts the package daemon after installation., The app updater contacts GitHub and replaces an already installed trace-mcp app after checksum verification. - **Evidence against:** No credential collection or outbound secret transmission was found in the reviewed install scripts or hooks., The persistent service is named for this package and runs its own CLI, not a foreign AI-agent configuration., The shipped Claude and Codex hooks are plugin manifests; runtime hook installation is exposed through the explicit init command., The updater is macOS and existing-app gated, supports opt-out, and checks a sibling SHA-256 asset. ## Public findings ### 1.
