Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source establishes an explicit user-command agent extension that persists hooks, permissions, and skill content and transmits session-derived data. There is no automatic npm lifecycle trigger or concrete covert malware behavior, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-08-30T00:49:34.473Z - **Finished:** 2026-08-30T00:52:01.403Z - **Download time:** 506 ms - **Static scan time:** 1034 ms - **AI review time:** 145388 ms - **Total time:** 146930 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The user-run setup installs persistent MCP configuration, hooks, permissions, and managed skills. The hook can send captured session content to the package service. - **Trigger:** The user runs the setup or install command; installed hooks then run during agent sessions. - **Impact:** It changes global agent control surfaces, pre-authorizes package tools, and transmits session-derived data to the service. - **Evidence paths:** package.json, lib/setup.mjs, lib/editors/claude.mjs, lib/capture.mjs, lib/skills.mjs, lib/diagnose.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-30T00:52:01.403Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent agent configuration and authenticated session capture. - **Rationale:** The source establishes an explicit user-command agent extension that persists hooks, permissions, and skill content and transmits session-derived data. There is no automatic npm lifecycle trigger or concrete covert malware behavior, so this warrants a warning rather than a block. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.claude/skills, ~/.codex/skills, ~/.cortex/org-skills-cache.json - **Network endpoints:** https://cortex-console.vercel.app/api/ingest, https://cortex-console.vercel.app/api/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Explicit setup rewrites Claude and Codex agent configuration and installs hooks., The Claude configuration pre-authorizes package namespaces, including authoring tools., A stop hook reads session data and posts an ingest body with the wired bearer token., Session-start repair fetches and installs server-provided skills into agent skill directories. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The configuration changes require the user to run setup or install., Network use targets the package service and the capture path redacts credential-shaped strings., No hidden payload, unrelated endpoint, or destructive behavior was found in the inspected source. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.123. - Review the evidence and your use of @theronap/cortex-mcp@0.9.123 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
