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:** 0.9.150 - **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. The package is not malicious by the install-hook policy because it has no npm lifecycle trigger and its control-surface changes require explicit CLI setup. Its persistent editor hooks, automatic session capture, and permission changes remain a real first-party agent-extension risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-12T08:52:48.503Z - **Finished:** 2026-09-12T08:53:56.894Z - **Download time:** 772 ms - **Static scan time:** 1347 ms - **AI review time:** 66271 ms - **Total time:** 68391 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:** An explicit installer can modify supported AI-editor configuration, add hooks, and enable session capture. The capture hook sends an ingest payload to the package's service; an optional Antigravity artifact can create a watcher after separate activation. - **Trigger:** The user runs cortex-mcp install or setup; the Antigravity watcher also requires the user to load its generated launchd plist. - **Impact:** Future editor sessions can run package commands, pre-authorize package MCP tools, and upload captured session-derived data to the service. - **Evidence paths:** lib/install.mjs, lib/editors/claude.mjs, lib/capture.mjs, lib/editors/antigravity.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T08:53:56.894Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-editor configuration, hook installation, and session-ingest upload. - **Rationale:** The package is not malicious by the install-hook policy because it has no npm lifecycle trigger and its control-surface changes require explicit CLI setup. Its persistent editor hooks, automatic session capture, and permission changes remain a real first-party agent-extension risk. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.cortex/editors.json, ~/.cortex/antigravity-sync.sh, ~/Library/LaunchAgents/com.cortex.antigravity-sync.plist - **Network endpoints:** https://agnoclast.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The explicit install command wires detected AI-editor adapters and writes a local capability manifest., Claude wiring adds a Stop hook that invokes this package and appends its MCP tool permissions., The capture path processes hook input and posts an ingest body to the Agnoclast API., The Antigravity adapter writes a launchd watcher artifact that invokes the stable package release. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The configuration changes are reached through explicit CLI subcommands, not package import or registry installation., Network traffic is directed to the package-aligned Agnoclast service and uses the configured token. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.150. - Review the evidence and your use of @theronap/cortex-mcp@0.9.150 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.
