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 3d ago · by lpm-firewall-ai

Source inspection shows a PATH-focused postinstall and user-invoked CLI setup against the package’s worker API. The reviewed agent configuration requires approval, and the flagged process and network behavior has a normal product role; no concrete attack behavior was found.

Static reason

One or more suspicious static signals were detected.

Trigger

Package installation runs the postinstall PATH setup; other reviewed behavior requires a CLI operation such as login or explicit agent configuration.

Impact

No credential theft, unauthorized account action, or unconsented agent control change was established.

Mechanism

The reviewed code adds a PATH block, pairs the CLI with its worker API through browser approval, gates project hooks on approval, and routes requests through a per-request proxy check.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest exposes the two CLI entrypoints and runs a postinstall PATH setup script; that script appends a marker-wrapped shell PATH block.
Login is an explicit CLI or REPL action. It uses the package’s worker API for device pairing and saves the resulting worker key after browser approval.
Agent hook configuration is gated by project approval; the MCP helper changes Claude configuration through an explicit approval command.
The MongoDB helper selects install or start actions for a local database, and the agent-stop helper terminates child processes.
The coding-provider default is OpenAI’s API, and proxy routing is checked per request.
