AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package has no install lifecycle hook, and the flagged credential flow sends account proof with a user token to the Cortex confidential-session endpoint for seat authorization. The persistence hint describes artifacts created by an editor wiring operation that are not activated automatically.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The MCP server contacts Cortex during use; setup, install, and channel operations require explicit CLI commands.
Impact
No unauthorized credential transfer, account action, or active persistence was found in the inspected paths.
Mechanism
Confidential-session proof accompanies the user’s Cortex token to the Cortex service for account and seat approval. Antigravity wiring writes configuration artifacts but does not activate its watcher.
AI rationale
The package has no install lifecycle hook, and the flagged credential flow sends account proof with a user token to the Cortex confidential-session endpoint for seat authorization. The persistence hint describes artifacts created by an editor wiring operation that are not activated automatically.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines a CLI and no lifecycle scripts; its stated purpose is connecting an AI assistant to Cortex.
- The flagged confidential-session flow sends account proof with a user token to the confidential agent-session endpoint on the configured Cortex service.
- The server checks for confidential seats and account proof as part of opening a named confidential brain; the package describes approval and account dedication requirements.
- Antigravity wiring writes a shell script and launch-agent plist, but says a person must run launchctl load to activate the watcher.
- The service’s canonical base URL is agnoclast.com.
Evidence against
- The apparent api.openai.com credential match is an OpenAI ID-token claim used to identify the signed-in account, not a request sending that token to OpenAI.
- The channel configuration is written by an explicit channel command, and the setup/install branches are explicit CLI commands.
