It also downloads a package-aligned application update for detected legacy app bundles. - **Trigger:** npm installation runs the postinstall lifecycle script. - **Impact:** A user-level service can persist and run the package CLI; legacy application bundles can be replaced after a network download. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, .codex-plugin/hooks/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T23:54:29.355Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall updater and launchd service bootstrap. - **Rationale:** The package performs automatic persistence and remote application replacement at install time, which is a meaningful lifecycle risk. The actions are limited to trace-mcp-owned paths and an explicit plugin manifest, with no confirmed malicious payload or exfiltration. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/Applications/trace-mcp.app, /Applications/trace-mcp.app - **Network endpoints:** api.github.com, 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The registry postinstall chain runs three package scripts automatically., The postinstall control-plane script writes and bootstraps a per-user macOS LaunchAgent., The postinstall updater downloads a release archive and checksum before replacing legacy app bundles., The bundled Codex plugin registers a Bash PreToolUse guard command. - **Evidence against:** No runtime dependency on trace-mcp itself is declared., The updater compares the downloaded archive with a SHA-256 value from a sibling release asset., The plugin hook is declared in a plugin manifest; the inspected postinstall code does not write Codex or Claude configuration., No credential collection or outbound secret transmission was found in the inspected lifecycle and hook sources. ## Public findings ### 1.
