nebula-notebook@0.2.32
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 a registry postinstall guard, a user-invoked server launcher, and protected API routing. No concrete malicious behavior was identified.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User invocation of the nebula-notebook command.
Impact
No unconsented mutation, credential collection, or confirmed exfiltration behavior was found.
Mechanism
The launcher starts the packaged local server; its protected API routes use authentication middleware.
AI rationale
Static inspection found a registry postinstall guard, a user-invoked server launcher, and protected API routing. No concrete malicious behavior was identified.

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 declares a postinstall handler.
- The postinstall handler exits when running from node_modules, so it does not run its checkout setup during registry installation.
- The command-line launcher starts the packaged server only when the user invokes the command.
- The server applies authentication middleware to protected API routes.
- The browser bundle contains a Jupyter widget CDN default, not a package-controlled collection endpoint.
Evidence against
- The server can invoke OpenSSL to create a local self-signed certificate during server startup.
- The browser bundle references the public jsDelivr CDN for widget assets.
