nebula-notebook@0.2.54
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 registry-install postinstall path exits before performing its checkout-only commands. Inspected runtime behavior is consistent with a local notebook service and contains no concrete malicious chain.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the command-line launcher or starts the server.
Impact
No confirmed unconsented mutation, credential export, remote payload execution, or destructive behavior was found.
Mechanism
The launcher starts the local server; the install hook does nothing for a registry dependency installation.
AI rationale
The registry-install postinstall path exits before performing its checkout-only commands. Inspected runtime behavior is consistent with a local notebook service and contains 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
- The install hook invokes the included postinstall script, which exits when installed under node_modules.
- The command-line launcher starts the packaged local server using the caller's arguments.
- Resource collection uses bounded GPU-status commands with a timeout.
- The frontend constructs authenticated requests from configured request settings.
- Session-token fallback is restricted to non-browser loopback requests.
- The only inspected outbound request checks this package's latest version at the npm registry.
