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 automatic lifecycle hook is guarded to exit for normal package installations, and the inspected executable behavior is user-invoked server launching. No concrete malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
No malicious trigger was identified; the server launcher is activated by an explicit command invocation.
Impact
No confirmed unconsented mutation, credential export, remote payload execution, or persistence was established.
Mechanism
The install hook exits for node_modules installations, while the launcher starts the packaged server and the browser bundle opens configured WebSocket connections.
AI rationale
The automatic lifecycle hook is guarded to exit for normal package installations, and the inspected executable behavior is user-invoked server launching. 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 manifest registers a postinstall script and separate explicit MCP setup commands.
- The postinstall script exits when installed under node_modules, so its repository convenience commands do not run for a normal dependency installation.
- The command-line launcher starts the packaged server only when the user invokes the package executable.
- The browser bundle uses a token only when opening its configured WebSocket connection.
