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 execution path. The remaining network and dynamic-configuration behavior is package-aligned and not evidence of an attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The CLI is explicitly launched by the user; the version check runs when the server starts.
Impact
No confirmed credential theft, data exfiltration, persistence, destructive action, or foreign agent-control mutation was found.
Mechanism
The launcher starts the package server. Resource collection invokes fixed local GPU utilities, while the update checker contacts the npm registry.
AI rationale
Static inspection found no concrete malicious execution path. The remaining network and dynamic-configuration behavior is package-aligned and not evidence of an attack.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest’s only install hook invokes the packaged postinstall script.
- The CLI starts the packaged server entry with caller-supplied arguments and inherited standard I/O.
- The postinstall script exits when running from node_modules, preventing its checkout dependency-install actions during normal package installation.
- The resource service runs fixed GPU-query commands rather than caller-provided shell input.
- The bundled dynamic require is conditional on an explicit Jupyter configuration flag or environment setting.
Evidence against
- The server performs an opt-out, daily version check against the npm registry.
- The browser bundle retains a dynamic local configuration require.
