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 2d ago · by lpm-firewall-aiThe flagged install hook skips normal npm dependency installations and only performs setup for repository subpackages when run from a checkout. The launcher and shell execution support the package’s notebook server and resource discovery; the foreign-host match is in a vendored-code comment, and no malicious credential flow was identified.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
npm installation, launching the server, or requesting resource information.
Impact
No malicious data collection, unrelated network contact, or unauthorized account action was identified in the reviewed paths.
Mechanism
The install hook skips when installed under node_modules; repository-local setup installs existing subpackage dependencies. The launcher starts the bundled server, whose resource service runs timed system queries.
AI rationale
The flagged install hook skips normal npm dependency installations and only performs setup for repository subpackages when run from a checkout. The launcher and shell execution support the package’s notebook server and resource discovery; the foreign-host match is in a vendored-code comment, and no malicious credential flow was identified.
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 exposes a launcher that starts its bundled server entry point.
- The postinstall script exits when its directory is under node_modules.
- Outside node_modules, postinstall installs dependencies for repository subpackages that exist beside the package and may build autocomplete.
- The resource service runs timed system commands to collect resource information, including GPU details.
- The server disables authentication only when explicit no-auth flags or environment settings are present.
Evidence against
- The reviewed install and process execution behavior is consistent with the advertised notebook server, repository setup, and resource discovery features.
- The foreign-host pointer in the bundled asset lands in a comment identifying vendored terminal-emulator code, not a credential transmission path.
