AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has no npm install lifecycle hook or self-dependency chain, so the configuration mutation is user-command initiated rather than unconsented install-time behavior. Its persistent hooks, data upload, and remote skill installation still warrant a warning as an agent-extension lifecycle risk.
Static reason
No blocking static signals were detected.
Trigger
A user runs cortex-mcp setup or install; configured AI-agent events then invoke its hooks.
Impact
The package gains continuing access through configured agent hooks and can place server-provided instructions in agent skill directories.
Mechanism
Agent configuration and hook installation with authenticated data upload and skill synchronization.
AI rationale
The package has no npm install lifecycle hook or self-dependency chain, so the configuration mutation is user-command initiated rather than unconsented install-time behavior. Its persistent hooks, data upload, and remote skill installation still warrant a warning as an agent-extension lifecycle risk.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit setup persists a Codex Stop hook that later runs this package through npx.
- The capture hook sends an authenticated session payload to the package service.
- The skill synchronizer fetches server-provided skill content and installs it into AI-agent skill directories.
- The Antigravity adapter writes an executable script and LaunchAgents plist.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
- Configuration changes are reached through explicit login, setup, or install CLI commands.
- No runtime dependency on this package itself is declared.
- No obfuscation, eval-style execution, credential theft, or unrelated endpoint was found.
