Adds a package-controlled MCP server to available AI clients and keeps it running across logins. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 4.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package modifies multiple third-party AI-client configuration files and starts a per-workspace daemon that persists at login. This occurs automatically for a local install, without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T14:17:46.994Z - **Finished:** 2026-08-03T14:18:18.916Z - **Download time:** 1268 ms - **Static scan time:** 5138 ms - **AI review time:** 25515 ms - **Total time:** 31922 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package modifies multiple third-party AI-client configuration files and starts a per-workspace daemon that persists at login. This occurs automatically for a local install, without an explicit setup command. - **Trigger:** npm postinstall for a repository-local install - **Impact:** Adds a package-controlled MCP server to available AI clients and keeps it running across logins. - **Evidence paths:** package.json, scripts/preinstall.js, dist/postinstall-hint.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-03T14:18:18.916Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic broad MCP-client injection plus OS login persistence - **Attack narrative:** Installing the package executes dist/postinstall-hint.js. It detects the install workspace, writes a codeatlas MCP entry into detected third-party AI-client configs, and registers/starts a launchd, systemd-user, or Windows logon task that runs its server against that workspace. These actions are automatic rather than gated behind an explicit setup command. - **Rationale:** The package performs concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces and establishes login persistence. Its stated product purpose does not remove the install-time consent issue. - **Files touched:** ~/.cursor/mcp.json, ~/.claude/settings.json, ~/.codex/config.json, ~/.continue/config.json, ~/.gemini/settings.json, ~/.config/codeatlas/setup-marker.json, ~/Library/LaunchAgents/com.codeatlas.\.plist, ~/.config/systemd/user/\.service - **Network endpoints:** http://localhost:7842 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., dist/postinstall-hint.js writes MCP entries to Claude, Cursor, Codex, Copilot, Continue, and Gemini configs., Postinstall starts login-persistent launchd, systemd, or Scheduled Task services., Postinstall uses INIT\_CWD to bind the daemon and injected server to the installing repository., README.md confirms zero-config client rewiring and daemon startup during npm install. - **Evidence against:** No confirmed non-local exfiltration in the inspected install hook., The persistent service launches the package's own local MCP server. ## Public findings ### 1.
