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 6d ago · by lpm-firewall-ai

Source inspection found a postinstall PATH setup hook and user-configured agent integrations with project approval checks. The scanner’s credential and execution signals were not supported as attack behavior by the inspected source.

Static reason

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

Trigger

Package installation runs the declared postinstall hook; agent hooks and MCP servers are used during turns.

Impact

No confirmed unauthorized credential transfer, agent control-surface mutation, or other attack impact was found.

Mechanism

The installer sets up PATH, while configured project hooks and MCP servers are gated by project approval. The inspected credential-related calls use configured service endpoints.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes CLI entrypoints and a postinstall hook; install-path.mjs uses a marker-wrapped shell configuration block for PATH setup.
The hooks configuration reads agent hooks for turns and includes project hooks only when the current project’s configuration is approved.
MCP configuration checks project server approval before exposing project servers for a turn.
The REPL’s default remote agent endpoint is an Ollama service; the coding-key helper recognizes getmarsic.cc hosts as keyless.
The worker sends its key to the configured API base; the coding-key lookup is a worker API request tied to the current job.
The inspected MongoDB, proxy, and agent-stop helpers support local database setup, per-request proxy routing, and stopping completed jobs.

Evidence against

The postinstall hook modifies shell configuration, but the inspected installer is scoped to PATH setup; no attack behavior was identified.
