nebula-notebook@0.2.12
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 inspection found an intentionally capable notebook server, not a malicious chain. Scanner signals stem from a guarded checkout-only postinstall hook and expected terminal/filesystem/server functionality.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm installation or explicit nebula-notebook CLI launch
Impact
No unconsented payload execution, credential exfiltration, or foreign AI-agent configuration mutation found.
Mechanism
guarded checkout dependency setup; user-invoked local notebook server
AI rationale
Static inspection found an intentionally capable notebook server, not a malicious chain. Scanner signals stem from a guarded checkout-only postinstall hook and expected terminal/filesystem/server functionality.

Evidence for AI clean decision
Evidence against
- package.json postinstall runs scripts/postinstall.cjs.
- scripts/postinstall.cjs exits immediately when installed under node_modules.
- The guarded helper only installs/builds checkout subpackages.
- bin/nebula-notebook.js only launches the bundled server on explicit CLI use.
- Runtime network use is a notify-only npm registry update check.
- Server file, terminal, and kernel features are authenticated notebook functionality.
