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 29d ago · by lpm-firewall-aiInspected source explains the scanner flags through package-local setup, notebook execution capabilities, fixed resource probes, and bundled library code. No concrete malicious chain or unresolved warning-worthy behavior was established.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installation invokes a guarded setup hook; an explicit CLI invocation starts the server.
Impact
No confirmed credential exfiltration, remote payload execution, or install-time foreign agent control mutation was found.
Mechanism
The hook skips node_modules installations, while runtime code launches local helpers and uses authentication guards. No malicious mechanism was established.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json invokes a postinstall hook that exits under node_modules; otherwise it installs dependencies within package subdirectories. No runtime self-dependency was found.
- The CLI launches the bundled Node server and passes through user arguments.
- The resource service executes fixed GPU inspection commands with bounded timeouts.
- The flagged browser bundle contains translation plural-expression compilation, Jupyter configuration loading, and schema-validation code.
- The update checker fetches package version metadata from the npm registry and reports availability without executing downloaded code.
- The server applies authentication middleware, and explicit no-auth mode requires a loopback bind address.
