Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.9.124 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. This is an explicit, first-party AI-agent extension with persistent hook capabilities and remote session ingestion, so it warrants a warning. No lifecycle trigger or concrete malicious chain was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-04T14:57:33.756Z - **Finished:** 2026-09-04T14:58:49.289Z - **Download time:** 513 ms - **Static scan time:** 1062 ms - **AI review time:** 73957 ms - **Total time:** 75533 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:** No automatic install-time attack surface was found. Explicit setup can register agent hooks that capture session content and send derived data to the Cortex service; an optional adapter can create inactive launchd artifacts. - **Trigger:** The user runs the setup or install CLI command; the configured Stop hook later runs during an agent session. - **Impact:** A user who elects to configure the package grants it access to configured agent-session content and a token-backed remote ingest channel. - **Evidence paths:** lib/setup.mjs, lib/capture.mjs, lib/editors/antigravity.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-04T14:58:49.289Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent configuration, hook registration, transcript capture, and optional launchd artifact creation. - **Rationale:** This is an explicit, first-party AI-agent extension with persistent hook capabilities and remote session ingestion, so it warrants a warning. No lifecycle trigger or concrete malicious chain was found. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.cortex/antigravity-sync.sh, ~/Library/LaunchAgents/com.cortex.antigravity-sync.plist - **Network endpoints:** https://cortex-console.vercel.app/api/ingest ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Explicit setup writes MCP configuration and a Stop hook into AI-agent settings., The hook reads session transcripts, resolves a stored token, and sends an ingest request to the Cortex service., The Antigravity adapter writes a launchd plist and executable sync script when its explicit wiring method is called. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare lifecycle hook., The configuration and hook changes are reachable through named CLI setup or install commands, not package installation., No hidden payload, credential theft, destructive action, or unconsented install-time mutation was found. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.124. - Review the evidence and your use of @theronap/cortex-mcp@0.9.124 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.
