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 only install hook exits for node_modules installations, and the reviewed runtime behavior is consistent with a local notebook server. No concrete malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
No malicious trigger was identified; the reviewed behaviors activate during normal installation or explicit server use.
Impact
No confirmed exfiltration, persistence, destructive action, or foreign agent-control mutation was established.
Mechanism
The registry-installed postinstall path exits, while the launcher starts the local server and resource helper performs bounded local probes.
AI rationale
The only install hook exits for node_modules installations, and the reviewed runtime behavior is consistent with a local notebook server. No concrete malicious behavior was found.
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package lifecycle hook invokes the local postinstall script.
- The command-line launcher starts the packaged server with the user's supplied arguments.
- Resource probing runs commands through a timeout-limited helper.
- The postinstall script exits when installed under node_modules.
- The browser bundle opens a terminal WebSocket using its configured connection.
- The server registers authentication middleware for protected API routes.
