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 19d ago · by lpm-firewall-aiSource inspection found that the registry-install postinstall path exits before running package-manager commands. The flagged process, network, and dynamic-code patterns support the package’s source-checkout setup, GPU reporting, update notification, and bundled Jupyter frontend; no concrete attack behavior was established.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installation or normal use of the notebook; the postinstall script exits when the package is installed under node_modules.
Impact
No unconsented installation mutation or other concrete attack effect was established.
Mechanism
The source-checkout postinstall installs subpackage dependencies, the launcher starts the bundled server, and fixed shell commands collect GPU information. The update check retrieves package version information from the npm registry.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares the postinstall script; the script exits when installed under node_modules and only installs subpackage dependencies in a source checkout.
- The launcher starts the package’s bundled server and forwards the caller’s arguments.
- The flagged shell calls use fixed NVIDIA and AMD GPU information commands.
- The update checker contacts the npm registry for version information and is started as a notify-only check outside client mode.
- The frontend’s file write is an application API request, and the other flagged bundle code reads Jupyter configuration through its configured path.
- The shim imports the main frontend bundle and contains bundled utility code.
