Gu CLI — the gu terminal plus the local worker that runs agent / OCR / PDF / embedding jobs on your Mac (Ollama / MLX / OpenAI-compatible).

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Inspected source supports ordinary CLI setup and interactive account pairing. The scanner's credential-redirect claim is not established by the inspected flow, and project MCP commands are gated on approval.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Installing the package globally with npm can trigger its postinstall; interactive CLI use can start account pairing.

Impact

The installer makes the CLI available in new shells; pairing configures the user's account. The inspected behavior does not establish an attack surface.

Mechanism

The installer may add the global npm bin directory to the user's shell configuration. Pairing communicates with the configured API base and stores the worker key in the user's configuration.

Decision evidence

public snapshot

AI called this Clean at 85.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall invokes a dedicated PATH setup script.
Install-time PATH changes are limited to global npm installs and skipped when the bin directory is already on PATH.
MCP project servers are runnable only when approved for that project.
The CLI exposes commands for the local worker and obtains missing account configuration through an interactive first-run flow.
Device pairing uses the package's configured API base and saves the resulting worker key in the user's configuration file.
The flagged API helper imports process and filesystem utilities as part of local API setup; the inspected source does not establish malicious behavior.

Evidence against

No inspected source establishes credential theft, an unrelated credential recipient, or malicious persistence.
The postinstall behavior updates shell PATH for global installs; it does not mutate a broad AI-agent control surface.
