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:** 0.9.258 - **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 inspected source supports a warning for the Antigravity platform integration, whose setup creates a watcher artifact that can run after separate activation. It does not establish a concrete attack or unconsented install-time mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-24T00:23:02.420Z - **Finished:** 2026-10-24T00:23:43.346Z - **Download time:** 1019 ms - **Static scan time:** 2033 ms - **AI review time:** 37874 ms - **Total time:** 40926 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 concrete attack was identified. The inspected source shows setup-time agent configuration changes and an Antigravity sync artifact that could create residual lifecycle risk if activated. - **Trigger:** A user runs setup for an editor; Antigravity synchronization requires the launch agent to be activated separately. - **Impact:** An activated watcher can run the sync script when Antigravity state changes; the inspected excerpts do not establish malicious behavior. - **Evidence paths:** lib/editors/antigravity.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-24T00:23:43.346Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup writes editor MCP configuration. The Antigravity adapter prepares a script and launch-agent file under the user's home directory. - **Rationale:** The inspected source supports a warning for the Antigravity platform integration, whose setup creates a watcher artifact that can run after separate activation. It does not establish a concrete attack or unconsented install-time mutation. - **Files touched:** lib/editors/codex.mjs, lib/editors/cursor.mjs, lib/setup.mjs, lib/editors/antigravity.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a CLI and has no install lifecycle hook., The editor adapters write MCP configuration, and the setup source shows a configuration write; these are setup-time changes., The Antigravity adapter uses the user's home directory and prepares a sync script and launch-agent path., The uninstall behavior is reached through a CLI command, and the source describes dry-run and purge behavior. - **Evidence against:** The Antigravity adapter says it does not load the launch agent; its watcher requires a separate activation step., No inspected source established an automatic install-time change, credential disclosure, or other concrete attack. ## Affected versions and remediation This report applies to @theronap/cortex-mcp@0.9.258. - Review the evidence and your use of @theronap/cortex-mcp@0.9.258 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.
