AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis package creates durable AI-agent hooks and can transmit session-derived content after explicit user setup, so it warrants a warning. No lifecycle script, hidden install execution, self-dependency chain, or concrete malicious behavior was found.
Static reason
No blocking static signals were detected.
Trigger
The user runs cortex-mcp setup or install; configured Stop and SessionStart hooks then run during later agent sessions.
Impact
Session-derived content can be sent to the configured Cortex service, and organization-provided skill text can be installed into agent skill directories. No automatic npm install-time trigger was found.
Mechanism
Explicit agent configuration, hook-based session capture, and remote skill synchronization.
AI rationale
This package creates durable AI-agent hooks and can transmit session-derived content after explicit user setup, so it warrants a warning. No lifecycle script, hidden install execution, self-dependency chain, or concrete malicious behavior was found.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit setup writes MCP credentials and recurring hooks into AI-agent configuration.
- The installed Stop hook reads a session transcript and posts a derived digest or fallback transcript tail to the Cortex API.
- Session-start repair fetches organization-provided skills and writes them into installed agent skill directories.
- The Claude setup adds an allowlist for the package's MCP tools, including authoring actions.
- The Antigravity adapter can create a launchd watcher artifact, though it does not load it.
Evidence against
- package.json has no preinstall, install, or postinstall script.
- All configuration changes require an explicit CLI setup or install command; no package import performs them.
- Network use is consistently directed to the package's configured Cortex service and authenticated with its token.
- The capture path redacts credential-shaped text before transmission.
