AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package’s flagged credential flow sends proof to the configured Cortex service; `https://api.openai.com/auth` is parsed as a JWT claim namespace, not contacted. Persistence-related artifacts require an explicit install command and the launchd job is not loaded automatically.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The MCP server contacts Cortex during normal operation; confidential-account proof is used when the server checks for confidential seats or a tool names a confidential brain. Editor configuration writes require an explicit install or setup command.
Impact
No automatic credential transfer to a foreign host or unrequested persistence was found. Explicit setup can modify agent configuration and create an inactive watcher.
Mechanism
The package sends account proof to its configured Cortex API base. The Antigravity adapter writes a script and plist but does not activate the launchd job.
AI rationale
The package’s flagged credential flow sends proof to the configured Cortex service; `https://api.openai.com/auth` is parsed as a JWT claim namespace, not contacted. Persistence-related artifacts require an explicit install command and the launchd job is not loaded automatically.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI and lists only release, promote, and rollback scripts; it declares no install lifecycle hook.
- The confidential-session proof is sent to the configured Cortex API endpoint, and the OpenAI URL string is used to parse a JWT claim locally, not as a network destination.
- The Antigravity watcher artifacts are written only through the explicit install path; the adapter does not load the launchd job and tells the user to activate it manually.
