AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo npm lifecycle hook or covert install-time execution was found. The package nevertheless performs explicit-user-command AI-agent configuration, automated capture, and network transfer, so it warrants a warning for dangerous extension capability.
Static reason
No blocking static signals were detected.
Trigger
A user runs cortex-mcp setup or install, then an installed editor hook fires.
Impact
Session-derived content and an authentication token are sent to the configured Agnoclast API; editor behavior is extended persistently until removed.
Mechanism
AI-editor MCP and hook wiring with transcript ingestion.
AI rationale
No npm lifecycle hook or covert install-time execution was found. The package nevertheless performs explicit-user-command AI-agent configuration, automated capture, and network transfer, so it warrants a warning for dangerous extension capability.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit install command wires every selected AI editor and records a capability manifest.
- Claude settings receive automatic Stop, SessionStart, and prompt-submission commands that run this package through npx.
- The capture hook reads a session transcript, builds an ingest body, and posts it with the configured token.
- The Antigravity adapter writes a launchd plist and executable watcher script, though it does not load the agent.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The configuration and hook changes are reachable through explicit CLI setup or install commands, not package installation or import.
- The observed network destination is the package-aligned Agnoclast service; no unrelated exfiltration endpoint or opaque payload loader was found.
- The launchd artifact is not activated by the package and its generated script exits if its local prerequisite is absent.
