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 15d ago · by lpm-firewall-ai

Source inspection found a PATH setup postinstall and ordinary CLI account configuration, with no confirmed malicious chain. The flagged MCP configuration location reads project configuration and does not establish an unconsented agent control-surface mutation.

Static reason

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

Trigger

Package installation invokes the postinstall hook; account requests occur when the user runs the CLI.

Impact

No confirmed malicious effect or attack surface was established.

Mechanism

The postinstall hook runs PATH setup. The REPL reads the worker key and API base from configuration and only enters first-run login through an interactive terminal.

AI rationale

Evidence

Decision evidence

public snapshot

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

Evidence for AI clean decision

The manifest’s postinstall hook invokes the package’s PATH setup script.
The REPL reads its worker key and API base from user configuration; its first-run login path requires an interactive terminal.
The MCP configuration helper targets the project’s .mcp.json file; the inspected location only reads and parses that file.
Client Expert defines its API at loopback, and MongoDB uses a local default URI.
The inspected flagged files show package functionality and setup context, with no confirmed attack behavior.
