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 7d ago · by lpm-firewall-ai

The scanner’s credential-redirection claim is not supported by the inspected source: login is explicit and pairs with the package’s worker API, while worker keys authenticate requests to the configured API. The postinstall is limited to PATH setup, and the inspected agent configuration paths include approval gates.

Static reason

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

Trigger

Package installation triggers the postinstall PATH setup; login and agent configuration operations require user action.

Impact

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

Mechanism

The postinstall adds the CLI binary directory to shell PATH when needed. Login pairs with the configured worker API, while project hooks and servers have approval flows.

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 postinstall runs install-path.mjs to help users find the CLI by adding its global binary directory to shell PATH.
Login is an explicit CLI action; device pairing uses the package’s worker API, and its flow asks the user to approve the pairing in a browser.
Worker keys are sent to the configured worker API as authentication for worker routes; the inspected source does not show transfer to an unrelated recipient.
Project hooks are run only when approved, and the agent hook settings location is a path helper rather than an automatic install-time mutation.
Project MCP server approval is an explicit configuration operation; the inspected MCP location is a path helper.
The inspected MongoDB, provider URL, proxy, and agent-stop code implements local service probing, provider URL vetting, per-request proxying, and stopping ended jobs.
