The running daemon later installs newer releases of the same package without an explicit update command. - **Trigger:** npm postinstall, then normal daemon runtime while automatic updates remain enabled - **Impact:** A later registry release can execute its postinstall and replace application or user-level launcher state automatically. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T01:26:57.430Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** self-updating lifecycle chain with LaunchAgent persistence - **Attack narrative:** The package invokes its postinstall automatically. That hook writes user-level launcher state and bootstraps a LaunchAgent. Once the daemon runs, it checks the npm registry and executes a forced global install of a newer trace-mcp release. That nested install re-enters the same postinstall chain, which can refresh persistence and download or replace installed application bundles. This gives a future package release an automatic path to execute install-time code and alter persistent local state without a user issuing an update command. - **Rationale:** The package implements a complete automatic self-update and lifecycle re-entry chain alongside persistent user-level service installation and application replacement. This is concrete install-hook abuse, not ordinary user-invoked setup. - **Files touched:** ~/.trace/, ~/.trace-mcp/, ~/Library/LaunchAgents/com.trace-mcp.server.plist, installed trace-mcp application bundles - **Network endpoints:** https://registry.npmjs.org/trace-mcp/latest, https://api.github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Its automatic postinstall runs two package scripts that alter user-level state., The postinstall writes and bootstraps a persistent macOS LaunchAgent., At runtime the daemon fetches the latest version and silently runs a forced global install of its own package., The install hook downloads release assets and can replace installed application bundles. - **Evidence against:** The release download code checks a sibling SHA-256 asset before applying the downloaded bundle., No direct credential harvesting or secret exfiltration was identified in the inspected paths. ## Affected versions and remediation This report applies to trace-mcp@3.25.1. - Avoid installing trace-mcp@3.25.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
