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 has a real, user-invoked agent-control and session-ingestion capability with remotely refreshed instructions. It lacks an npm lifecycle trigger or concrete evidence of malicious execution, so warning is more proportionate than blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-08T09:52:48.181Z - **Finished:** 2026-09-08T09:54:14.530Z - **Download time:** 756 ms - **Static scan time:** 1412 ms - **AI review time:** 84180 ms - **Total time:** 86349 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 setup or install wires MCP servers, agent hooks, and managed skills. Later hooks can transmit captured session content to Agnoclast and can replace skills from the service. - **Trigger:** The user runs setup or install, then starts or ends an enabled agent session. - **Impact:** Future agent sessions can execute package commands, receive remotely supplied skills, and send captured session material to the configured service. - **Evidence paths:** lib/setup.mjs, lib/editors/claude.mjs, lib/capture.mjs, lib/skills.mjs, lib/editors/antigravity.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T09:54:14.530Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent configuration mutation, automatic hooks, remote skill synchronization, and session ingestion. - **Rationale:** The package has a real, user-invoked agent-control and session-ingestion capability with remotely refreshed instructions. It lacks an npm lifecycle trigger or concrete evidence of malicious execution, so warning is more proportionate than blocking. - **Files touched:** ~/.claude.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.claude/skills/\/SKILL.md, ~/.codex/skills/\/SKILL.md, ~/.cortex/antigravity-sync.sh, ~/Library/LaunchAgents/com.cortex.antigravity-sync.plist - **Network endpoints:** https://agnoclast.com/api/ingest, https://agnoclast.com/api/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The explicit setup command adds automatic Claude hooks, including a session-start command that refreshes skills., The capture hook reads session data and posts an ingestion body with its bearer token to Agnoclast., Server-provided skills are installed into detected Claude and Codex skill directories during automatic repair., The Antigravity adapter writes a launchd plist and shell script, although it does not load the agent itself. - **Evidence against:** package.json has no preinstall, install, or postinstall script., The configuration and hook changes require an explicit setup or install command., Network requests use the package-aligned agnoclast.com service and an explicit token., No obfuscation, evaluator use, credential harvesting beyond the configured token, or self-dependency was found. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.137. - Review the evidence and your use of @theronap/cortex-mcp@0.9.137 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.
