nebula-notebook@0.2.56
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 install hook is inert for normal node_modules installation, and inspected runtime behavior is consistent with a local notebook service. No concrete malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user invokes the CLI or runs the local server.
Impact
No unconsented installation-time mutation, credential export, remote payload execution, or destructive behavior was established.
Mechanism
The launcher starts the packaged server; GPU checks run fixed local diagnostic commands, and the update checker queries the npm registry.
AI rationale
The install hook is inert for normal node_modules installation, and inspected runtime behavior is consistent with a local notebook service. No concrete malicious behavior was found.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The lifecycle hook exits when installed under node_modules, so its recursive install code does not run for normal package installation.
- The CLI starts the packaged local server with inherited standard input and output.
- Resource collection uses fixed GPU diagnostic commands.
- Session-token fallback is restricted to loopback, non-browser requests and excludes another operating-system user.
- The browser bundle requests settings through its configured server connection.
- The only fixed external endpoint found is the package's npm registry update check.
