@tiens.nguyen/gu-cli@1.0.780

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 inspected source supports a package-aligned CLI and worker flow, with credentials directed through the configured worker API setting. The static hints do not establish credential theft or malicious agent configuration behavior.

Static reason

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

Trigger

npm installation runs the declared postinstall helper; worker requests occur when the user runs the CLI.

Impact

No confirmed malicious impact was identified in the reviewed excerpts.

Mechanism

The inspected source identifies local worker configuration, a configured API base, and local MongoDB availability checks.

AI rationale

Evidence

package.jsoninstall-path.mjsgu-repl.mjsmcp-config.mjsmongo-native.mjsclient-expert-api.mjs

Decision evidence

public snapshot

AI called this Clean at 72.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json defines a postinstall hook that runs the package's install-path helper.
gu-cli exposes an explicit --api-base option for configuring the worker service.
gu-repl loads the worker key and API base from local user configuration.
mcp-config maps user and project MCP configuration paths; the required target excerpt shows JSON reading behavior.
mongo-native.mjs sends a MongoDB protocol hello to the configured host and port.
client-expert-api starts a local API process using the package's configured local directory.

Evidence against

The reviewed credential flow uses the configured worker API base rather than showing a separate hidden credential recipient.
The inspected MongoDB code performs a protocol availability check; it does not show credential collection or exfiltration.
The provided MCP target location shows configuration reading, not an agent-control write.
