Google's open-source terminal agent that brings Gemini to your command line.
Gemini CLI reads codebases, edits files, runs commands and calls MCP tools from your terminal, signing in with a Google account or API key.
Known restrictions apply, or some features are unavailable in Hong Kong.
Basis: official supported-region list
The code is freely available on GitHub, but the model service relies on the Gemini API, and Google's official Gemini API / AI Studio region list excludes Hong Kong. Whether the free Google-account sign-in works in Hong Kong is unverified.
