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 22d ago · by lpm-firewall-aiSource inspection found no concrete malicious behavior. The postinstall path exits under node_modules, the shell commands are limited to GPU inventory, and the network check retrieves the package’s latest version for notification.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Package installation or user launch of the notebook server.
Impact
No harmful effect was identified; observed effects are local setup, resource reporting, and an update notice.
Mechanism
The checkout-only postinstall sets up local subpackages; runtime code starts the server, collects hardware resource data, and checks the npm registry for a newer package version.
AI rationale
Source inspection found no concrete malicious behavior. The postinstall path exits under node_modules, the shell commands are limited to GPU inventory, and the network check retrieves the package’s latest version for notification.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest registers a postinstall script; that script exits under node_modules and otherwise targets local subpackages found in a repository checkout.
- The checkout setup runs npm installs and a local build for those subpackages.
- The launcher starts the packaged server and passes through the caller’s arguments and environment.
- GPU resource collection uses fixed NVIDIA and AMD inventory commands with a timeout.
- The background update check fetches this package’s latest npm version and runs as a notify-only check.
- The inspected frontend excerpts use Jupyter server settings and the package’s own server authentication endpoints.
