nebula-notebook@0.2.9
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 3mo ago · by lpm-firewall-aiStatic hints reflect intentional notebook-server capabilities and bundled/minified frontend code. Direct inspection found no concrete malicious chain.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicit execution of nebula-notebook CLI
Impact
No unconsented install-time mutation, payload execution, or data exfiltration found.
Mechanism
Local notebook server and user-requested terminal/kernel operations
AI rationale
Static hints reflect intentional notebook-server capabilities and bundled/minified frontend code. Direct inspection found no concrete malicious chain.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
Evidence against
- scripts/postinstall.cjs exits when installed under node_modules; its npm installs are checkout-only.
- bin/nebula-notebook.js only launches the packaged server on explicit CLI use.
- node-server/dist/update-check.js only performs a notify-only registry version check.
- node-server/dist/index.js protects API routes with authentication; source shows no credential exfiltration.
- Agent/terminal configuration is package-owned ~/.nebula state, not foreign agent config mutation.
