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 does not support the scanner's credential-redirection claim: the REPL authenticates against the configured API, and Client Expert's shared model endpoint is part of setup. The postinstall hook is conditional PATH setup, and no concrete malicious chain was found.

Static reason

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

Trigger

Package installation for PATH setup, or explicit CLI login and Client Expert setup for runtime configuration.

Impact

These behaviors support CLI setup and service use; inspected source does not establish covert credential exfiltration or unconsented agent control-surface mutation.

Mechanism

The installer checks platform, CI, npm prefix, global-install status, and PATH before editing shell startup files. The REPL uses the configured API base for worker authentication; provider setup guards against sending API keys over public HTTP.

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json runs a postinstall that invokes install-path.mjs; the hook is limited to conditional PATH setup.
The REPL uses a worker key with its configured API base for sign-in; the source does not show an unrelated credential recipient.
Client Expert offers a configurable shared model endpoint as part of explicit setup.
The provider setup source describes refusing public HTTP endpoints that would expose API keys in clear text.
The MCP configuration code reads user and project configuration files; it does not establish an unconsented install-time agent mutation.
The flagged process stopping helper sends termination signals to a child process.

Evidence against

The postinstall can modify a shell rc file to add the global npm bin directory to PATH.
Client Expert setup can run npm install in its API directory and uses a shared remote model endpoint.
