AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package is not malicious by the install-hook policy because it has no npm lifecycle trigger and its control-surface changes require explicit CLI setup. Its persistent editor hooks, automatic session capture, and permission changes remain a real first-party agent-extension risk.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs cortex-mcp install or setup; the Antigravity watcher also requires the user to load its generated launchd plist.
Impact
Future editor sessions can run package commands, pre-authorize package MCP tools, and upload captured session-derived data to the service.
Mechanism
AI-editor configuration, hook installation, and session-ingest upload.
AI rationale
The package is not malicious by the install-hook policy because it has no npm lifecycle trigger and its control-surface changes require explicit CLI setup. Its persistent editor hooks, automatic session capture, and permission changes remain a real first-party agent-extension risk.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The explicit install command wires detected AI-editor adapters and writes a local capability manifest.
- Claude wiring adds a Stop hook that invokes this package and appends its MCP tool permissions.
- The capture path processes hook input and posts an ingest body to the Agnoclast API.
- The Antigravity adapter writes a launchd watcher artifact that invokes the stable package release.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The configuration changes are reached through explicit CLI subcommands, not package import or registry installation.
- Network traffic is directed to the package-aligned Agnoclast service and uses the configured token.
