AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has dangerous agent-extension capabilities and session-data transmission, but they are activated by explicit user commands and are aligned with the package's integration function. No npm install lifecycle hook, covert execution path, or concrete malicious chain was found.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs the cortex-mcp setup or install command; Antigravity also requires the user to load its plist.
Impact
The configured assistants can run this package on hook events and session-derived content can be transmitted to the package service.
Mechanism
Editor configuration, hook installation, session capture, and authenticated API posting.
AI rationale
The package has dangerous agent-extension capabilities and session-data transmission, but they are activated by explicit user commands and are aligned with the package's integration function. No npm install lifecycle hook, covert execution path, or concrete malicious chain was found.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The explicit install command wires MCP entries, hooks, and permissions into detected AI-editor configurations.
- A stop hook reads session transcripts and posts derived content or a fallback transcript to the Agnoclast API.
- The Antigravity adapter writes a launchd plist and a script that invokes this package through npx at a moving stable tag.
- The package can add allow rules for its MCP tools, reducing prompts for those capabilities.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The configuration and hook changes are reached through explicit setup or install commands, not package installation.
- The launchd artifact is not loaded by the package; its code tells the user to load it manually.
- No obfuscated loader, eval-style execution, credential harvesting, or unrelated exfiltration path was found.
