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

The source shows application-aligned credential forwarding to the configured service and bounded setup behavior. The scanner’s credential-redirection and agent-configuration signals were not substantiated as malicious behavior in the inspected paths.

Static reason

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

Trigger

User runs the CLI or explicitly configures a provider or MCP server.

Impact

These inspected actions support ordinary CLI operation and setup; no unrelated credential recipient or unconsented agent-control mutation was established.

Mechanism

The CLI uses its configured API base for worker requests and user-entered coding keys; the local API defaults to loopback. The postinstall helper adjusts PATH for eligible global installs.

AI rationale

Evidence

~/.gonext/worker.env~/.gonext/mcp.json

Network endpoints1

Decision evidence

public snapshot

AI called this Clean at 83.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

The postinstall runs a PATH setup helper; that helper avoids shell-profile changes for local installs.
Worker credentials are read from local configuration and sent to the configured API base; coding keys are posted to that same API.
The MCP configuration helper reads user configuration and writes it atomically when invoked.
The local API uses loopback by default, and MongoDB process setup supports the package’s local service workflow.

Evidence against

The flagged gateway is the CLI’s configured default service endpoint; source shows worker credentials and user-provided coding keys being sent to its API as part of the application workflow.
No inspected source showed credential collection for an unrelated recipient, unsolicited foreign agent configuration mutation, or destructive behavior.
