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-aiStatic inspection found a node_modules-guarded lifecycle script, a local server launcher, bounded local GPU queries, and a package-aligned update check. No concrete malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The launcher runs when the user invokes the package command; the update check runs with the server unless disabled.
Impact
No credential exfiltration, foreign agent-control mutation, destructive action, or remote payload execution was identified.
Mechanism
The launcher starts the bundled server. The update check requests the fixed npm registry endpoint and does not install code.
AI rationale
Static inspection found a node_modules-guarded lifecycle script, a local server launcher, bounded local GPU queries, and a package-aligned update check. No concrete malicious behavior was found.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package declares a postinstall hook, but its script exits when running from node_modules.
- The command-line launcher starts only the packaged server entrypoint.
- GPU inspection invokes fixed local hardware-status commands.
- The browser bundle renders SVG content as a data URL image.
- The only identified fixed external endpoint is the package's npm registry update check.
