AI-native notebook computing environment — real Jupyter kernels, real filesystem, built to be driven by agents (Claude Code / Codex) via MCP
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe lifecycle hook is explicitly inactive when installed as a dependency, and the inspected runtime behavior is consistent with a local notebook service. No concrete attack behavior was found.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The user runs the package command or requests resource information from the running server.
Impact
No confirmed credential theft, data exfiltration, persistence, destructive behavior, or unconsented agent-control mutation was found.
Mechanism
The launcher starts the bundled server; resource collection runs fixed GPU utility commands with a timeout. The install hook is inactive for node_modules installs.
AI rationale
The lifecycle hook is explicitly inactive when installed as a dependency, and the inspected runtime behavior is consistent with a local notebook service. No concrete attack behavior was found.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- Package metadata defines the published command and its postinstall hook; it has no runtime dependency on its own package name.
- The command starts the packaged local server with the caller's arguments and environment.
- The postinstall script exits when running under node_modules, so registry installation does not run its nested npm installs.
- Resource collection only invokes fixed GPU-information commands with a timeout.
- The bundled client uses Jupyter-style request authentication handling; no package-controlled exfiltration endpoint was found in the inspected paths.
