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 flagged primitives have package-aligned implementations and activation paths, including a registry-install guard and authenticated runtime routes. Source inspection did not establish concrete malicious behavior; scanner labels alone do not justify blocking.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installation invokes a guarded setup hook; explicitly running the CLI starts the notebook server.
Impact
No malicious mutation, credential exfiltration, or remote payload execution was established from inspected source.
Mechanism
The hook skips dependency installations, while runtime code launches the local server, collects GPU status, and checks package version metadata.
AI rationale
The flagged primitives have package-aligned implementations and activation paths, including a registry-install guard and authenticated runtime routes. Source inspection did not establish concrete malicious behavior; scanner labels alone do not justify blocking.

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 invokes scripts/postinstall.cjs; that hook exits under node_modules and otherwise installs fixed subpackage dependencies. No runtime self-dependency is declared.
- The CLI explicitly launches the bundled server with caller arguments; server API requests pass through authentication middleware.
- Resource collection executes fixed NVIDIA and ROCm status commands with timeouts.
- The browser bundle contains notebook server request handling with a configured base URL check and same-origin credentials.
- The update checker fetches this package's npm version metadata and reports availability without installing updates.
- Dynamic function construction in the services shim implements template compilation.
