Installing the package runs code that establishes and starts a package-owned background service on macOS. Its separately installed plugin can control agent Bash-tool decisions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-27T18:03:01.117Z - **Finished:** 2026-08-27T18:04:09.218Z - **Download time:** 766 ms - **Static scan time:** 2919 ms - **AI review time:** 64414 ms - **Total time:** 68101 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs code that establishes and starts a package-owned background service on macOS. Its separately installed plugin can control agent Bash-tool decisions. - **Trigger:** npm installation, with the LaunchAgent behavior limited to macOS; plugin hooks run only after explicit plugin installation. - **Impact:** A user can receive an automatically persistent trace-mcp daemon, and an explicitly installed plugin can constrain agent tool use. No credential theft or foreign agent-control mutation was confirmed. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs, .codex-plugin/hooks/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-08-27T18:04:09.218Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall creates a trace-mcp launcher and persistent LaunchAgent; plugin hook emits agent permission decisions. - **Rationale:** This is not malicious by source evidence, but unconsented install-time persistence and a package-owned agent extension are meaningful lifecycle risk. The package policy calls for a warning for this first-party setup rather than a block. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist - **Network endpoints:** https://api.github.com/repos/${GITHUB\_REPO}/releases/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The npm postinstall chain runs a control-plane script automatically., On macOS, postinstall writes and bootstraps a persistent trace-mcp LaunchAgent with RunAtLoad and KeepAlive., The package ships an opt-in Codex plugin hook that can deny Bash tool calls., Postinstall also fetches and replaces an already installed trace-mcp desktop app from GitHub releases. - **Evidence against:** The LaunchAgent and files are named for trace-mcp, not a foreign agent configuration., The Codex hook is declared in a plugin manifest and requires explicit plugin installation., The app updater checks a sibling SHA-256 asset and does not run shell commands for extraction., No source evidence showed credential harvesting, secret exfiltration, or remote code evaluation. ## Public findings ### 1.
