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:** 0.9.117 - **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 not malicious by the stated boundary because the control-surface writes require explicit user commands and no npm lifecycle hook performs them. It warrants a warning because it persists hooks and permissions in multiple AI-editor control surfaces and transmits session-derived data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-27T23:45:08.772Z - **Finished:** 2026-08-27T23:46:20.605Z - **Download time:** 754 ms - **Static scan time:** 1129 ms - **AI review time:** 69950 ms - **Total time:** 71833 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:** Explicit setup or install changes AI-editor configuration, hooks, and MCP permissions. Hook execution can upload redacted session-derived data to the package's Cortex service. - **Trigger:** The user runs login, setup, install, or repair; configured editor hook events then invoke the package. - **Impact:** The package can persist within configured editor workflows, grant its MCP tools permissions, and send captured session information to its service. - **Evidence paths:** package.json, bin/cortex-mcp.mjs, lib/setup.mjs, lib/install.mjs, lib/editors/claude.mjs, lib/editors/codex.mjs, lib/editors/antigravity.mjs, lib/capture.mjs, lib/diagnose.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-27T23:46:20.605Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked AI-editor extension setup with session capture and context injection. - **Rationale:** This is not malicious by the stated boundary because the control-surface writes require explicit user commands and no npm lifecycle hook performs them. It warrants a warning because it persists hooks and permissions in multiple AI-editor control surfaces and transmits session-derived data. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.cursor/mcp.json, ~/.cortex/editors.json, ~/.cortex/antigravity-sync.sh, ~/Library/LaunchAgents/com.cortex.antigravity-sync.plist - **Network endpoints:** https://cortex-console.vercel.app, https://cortex-console.vercel.app/api/ingest ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The explicit install command wires detected AI editors and records a local capability manifest., Claude setup adds a prompt-time hook and pre-authorizes the package's MCP tools., Codex setup writes an MCP server entry and a Stop hook., The capture hook posts session-derived data to the Cortex API., The Antigravity option writes a launchd plist and executable wrapper. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Configuration changes require an explicit setup, install, repair, or login command., The capture path redacts credential-shaped transcript content before upload., No source evidence shows credential theft, destructive behavior, hidden remote code loading, or an unconsented install-time mutation. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.117. - Review the evidence and your use of @theronap/cortex-mcp@0.9.117 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.
