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-aiStatic inspection found no concrete malicious behavior. The install hook is inactive for normal npm dependency installation, and the inspected network request is a package-aligned version check.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User invocation of the command-line launcher or server startup.
Impact
No confirmed malicious execution, credential collection, exfiltration, persistence, or destructive behavior was found.
Mechanism
The launcher starts the bundled server; the installed postinstall hook exits without performing setup.
AI rationale
Static inspection found no concrete malicious behavior. The install hook is inactive for normal npm dependency installation, and the inspected network request is a package-aligned version check.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package declares a postinstall hook, but its hook immediately exits when installed under node_modules.
- The command-line launcher only starts the bundled local server and forwards user arguments.
- GPU inspection uses fixed local vendor commands rather than user-controlled shell input.
- The bundled browser asset handles Jupyter widget model loading.
- The only inspected outbound endpoint is the package's npm registry update check.
