Installing the package runs scripts that establish a trace-mcp launcher and, on macOS, a persistent trace-mcp daemon. This is a first-party lifecycle mechanism, but it occurs without a separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-28T04:42:17.223Z - **Finished:** 2026-08-28T04:43:19.275Z - **Download time:** 774 ms - **Static scan time:** 3383 ms - **AI review time:** 57893 ms - **Total time:** 62052 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs scripts that establish a trace-mcp launcher and, on macOS, a persistent trace-mcp daemon. This is a first-party lifecycle mechanism, but it occurs without a separate setup command. - **Trigger:** npm postinstall; macOS launchd then starts the trace-mcp daemon at login. - **Impact:** The package can persist and run its own local service; no confirmed cross-agent configuration takeover or exfiltration is present. - **Evidence paths:** package.json, scripts/postinstall-app.mjs, scripts/postinstall-control-plane.mjs, .claude-plugin/.mcp.json, .codex-plugin/.mcp.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:43:19.275Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes a package-owned launcher, launch-agent plist, and optional GitHub-downloaded app update. - **Rationale:** The package has a real automatic persistence and update surface, so it warrants a warning. The inspected source does not show malicious collection, exfiltration, foreign AI-agent control-surface writes, or concealed payload execution. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/.trace-mcp/daemon.log - **Network endpoints:** https://api.github.com/repos/${GITHUB\_REPO}/releases/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically creates a per-user launcher and, on macOS, a persistent launch agent., The launch agent starts the package daemon at login and keeps it alive., Postinstall also downloads a desktop-app release from GitHub when an installed app is found. - **Evidence against:** The persistence is scoped to trace-mcp paths and its own daemon, not foreign AI-agent settings., The packaged Claude and Codex plugin files declaratively register only the trace-mcp command., No source evidence shows credential harvesting, data exfiltration, or hidden remote command execution. ## Public findings ### 1.
