nebula-notebook@0.2.63
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 inspected source shows a notebook runtime with guarded installation behavior and package-aligned execution capabilities. No concrete malicious chain or unresolved attack surface was established.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installation invokes the guarded postinstall hook; running the CLI starts the notebook server.
Impact
No malicious credential export, foreign agent configuration mutation, or hidden payload execution was established.
Mechanism
Local dependency setup, server launching, GPU diagnostics, and notebook widget loading are package-aligned behaviors.
AI rationale
The inspected source shows a notebook runtime with guarded installation behavior and package-aligned execution capabilities. No concrete malicious chain or unresolved attack surface was established.

Decision evidence
public snapshotAI called this Clean at 89.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook exits under node_modules; otherwise it installs and builds local subpackages.
- The CLI launches the bundled notebook server with the user's arguments.
- Resource collection runs fixed GPU diagnostic commands with timeouts.
- The browser bundle contains notebook authentication and widget loading code; its request helper checks the configured notebook base URL.
- Explicit no-auth mode defaults to loopback and rejects non-loopback binding.
- The update checker reads version metadata from the npm registry without installing or executing updates.
