The same lifecycle flow can download and replace application bundles, and a bundled updater can reinstall the package globally. - **Trigger:** npm installation or upgrade runs postinstall; later application update handling can invoke a global npm install. - **Impact:** The package gains automatic execution through a LaunchAgent and can replace local application code outside the npm package directory. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, scripts/apply-pending-update.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T01:16:54.569Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall persistence, remote application replacement, and recursive global package installation. - **Attack narrative:** Installing the package automatically runs code that writes a launcher under the user's home directory and creates a launchd service configured with RunAtLoad and KeepAlive. That service executes the package CLI independently of the install command. The postinstall path also contacts GitHub for a release archive and can swap existing application bundles. A bundled update helper then invokes npm to globally install trace-mcp again, re-entering the lifecycle path. - **Rationale:** This is unconsented install-time persistence for an MCP control service, combined with remote code delivery and a self-reinstallation path. Integrity checks on the downloaded archive do not remove the broad automatic mutation and persistence behavior. - **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 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall chain automatically., Postinstall writes a user-home launcher configuration and installs an executable shim., On macOS it creates and bootstraps a persistent LaunchAgent that starts the package server at login and keeps it alive., The lifecycle updater downloads a release archive and replaces installed application bundles., A bundled updater can invoke npm to globally install trace-mcp again. - **Evidence against:** The updater verifies a SHA-256 value supplied alongside the downloaded release., Child-process calls use argument arrays rather than a shell in the inspected lifecycle code. ## Public findings ### 1.
