nebula-notebook@0.2.30
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 2mo ago · by lpm-firewall-aiThe install hook is explicitly disabled for npm dependency installs, while the flagged process and file operations are runtime features of the notebook application. Source inspection found no concrete malicious chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user runs the nebula-notebook command and interacts with its local server.
Impact
It can operate on files and shells selected through the running notebook service; no unconsented install-time or covert exfiltration behavior was found.
Mechanism
User-invoked notebook, filesystem, and terminal service.
AI rationale
The install hook is explicitly disabled for npm dependency installs, while the flagged process and file operations are runtime features of the notebook application. Source inspection found no concrete malicious chain.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines a postinstall hook.
- The runtime server can create user-facing terminal sessions and manage notebook files.
Evidence against
- The postinstall script exits when installed under node_modules, so published dependency installation does not run its nested npm installs.
- The command-line launcher only starts the bundled local server and forwards user-supplied arguments.
- The only fixed outbound endpoint found is the npm registry version check; it reads a version and logs an update notice.
- No credential harvesting, external payload download, obfuscated loader, or foreign AI-agent configuration mutation was found.
