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 inspected lifecycle hook is inactive for registry dependency installs, and the active code paths are consistent with a local notebook application. No concrete malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
The command-line launcher is explicitly invoked by the user.
Impact
No unconsented persistence, credential export, remote payload execution, or destructive action was identified.
Mechanism
The launcher starts the packaged server; the install hook exits for normal dependency installation.
AI rationale
The inspected lifecycle hook is inactive for registry dependency installs, and the active code paths are consistent with a local notebook application. No concrete malicious behavior was found.
Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package declares a user-invoked command-line launcher.
- The launcher starts the packaged Node server with inherited standard input/output and environment.
- The install hook exits when the package is installed under node_modules.
- GPU collection invokes fixed vendor diagnostic commands with a timeout.
- The browser bundle creates a WebSocket from its configured connection settings.
- Session-token fallback is limited to non-browser loopback callers and rejects other local users.
