On macOS it writes and bootstraps a persistent launchd daemon, and it can fetch application updates from GitHub. - **Trigger:** npm install or npm update, including local installation because the manifest has a postinstall hook. - **Impact:** A package process can be started at login and kept running without an explicit setup command; update code can download a replacement application bundle. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-30T16:55:40.103Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall persistence through a launchd agent and package-owned launcher shim. - **Rationale:** The source establishes automatic package-owned persistence and remote update behavior, but it does not show credential theft, foreign AI-agent configuration changes, or covert exfiltration. This warrants a warning rather than a publication block under the stated lifecycle policy. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist - **Network endpoints:** api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The automatic postinstall chain runs a control-plane installer., That installer writes a user launcher and registers a macOS LaunchAgent., The generated LaunchAgent starts at login and is configured to stay alive., Postinstall can query GitHub releases and download a replacement application bundle. - **Evidence against:** The control-plane files and service are named for this package rather than modifying an AI-agent configuration., The screenshot script's dynamic Electron evaluation is a development screenshot harness., The advertised-tools script starts the local server only when the developer explicitly runs that script. ## Public findings ### 1.
