nebula-notebook@0.2.11
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-aiThe flagged lifecycle behavior is explicitly checkout-only and exits in node_modules. Source inspection supports a user-invoked notebook/terminal application, not malicious execution or exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs nebula-notebook and authenticates to its server.
Impact
User-invoked commands can run within the notebook environment; no unconsented install-time or remote attack chain was found.
Mechanism
authenticated local notebook, terminal, and kernel service
AI rationale
The flagged lifecycle behavior is explicitly checkout-only and exits in node_modules. Source inspection supports a user-invoked notebook/terminal application, not malicious execution or exfiltration.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines postinstall, and scripts/postinstall.cjs invokes npm install in checkout subpackages.
- Runtime server intentionally exposes authenticated notebook, kernel, and PTY capabilities.
Evidence against
- scripts/postinstall.cjs exits before any install work when located under node_modules.
- bin/nebula-notebook.js only launches the packaged server with user-provided CLI arguments.
- Terminal and agent state writes are package-owned ~/.nebula files and occur only through the running authenticated service.
- node-server/dist/update-check.js only fetches the package's npm latest endpoint and never installs code.
- No credential harvesting, arbitrary remote payload download, obfuscated loader, or foreign AI-agent config mutation found.
