AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has no npm install lifecycle hook, but explicit setup installs persistent AI-agent hooks and can send session-derived data to its service. That is a real extension lifecycle risk rather than evidence of malicious install-time behavior.
Static reason
No blocking static signals were detected.
Trigger
The user runs cortex-mcp setup or install; later configured editor events invoke its hooks.
Impact
Automatic collection and transmission of session-derived data, plus durable changes to selected AI-editor configuration.
Mechanism
Explicit CLI wiring of MCP servers, hooks, and an optional launchd watcher.
AI rationale
The package has no npm install lifecycle hook, but explicit setup installs persistent AI-agent hooks and can send session-derived data to its service. That is a real extension lifecycle risk rather than evidence of malicious install-time behavior.

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 an MCP server and token into the user's Claude configuration.
- The setup command installs automatic Stop, SessionStart, and UserPromptSubmit hooks that invoke this package through npx.
- A hook reads a local assistant transcript and can POST its derived data to the Agnoclast API.
- The Antigravity adapter writes a launchd watcher and shell script, though activation requires a separate user command.
Evidence against
- package.json has no preinstall, install, or postinstall script.
- Configuration and hooks are reached only through explicit CLI setup or install commands.
- The network host is the package's named Agnoclast service, and capture redacts credential-shaped strings before processing.
- No hidden evaluator, obfuscated payload, arbitrary shell construction, or automatic install-time mutation was found.
