Google is introducing Gemini CLI, an open-source AI agent that offers lightweight access to Gemini, Google's conversational chatbot that is based on Google's multimodal large language model (LLM), also called Gemini, from terminals.

Now in preview, Gemini CLI provides AI capabilities including code understanding and file manipulation as well as command execution and troubleshooting. Google says the tool offers a fundamental upgrade to your command line experience, enabling you to write code, debug issues and streamline your workflow with natural language.

The agent has a number of built-in tools, starting with the ability to query and edit large codebases in and beyond Gemini's 1M token context window. The tool can automate operational tasks, like querying pull requests or handling rebases. It can also be used to generate new apps from PDFs or sketches, using Gemini's multimodal capabilities.

The Google Search tool that is built in to Gemini can be used to ground prompts by adding your own data to get better results by providing real-time, external context to the model.

The agent comes with built-in support for the Model Context Protocol (MCP) along with bundled extensions to make use of other MCP servers, including media generation with Imagen, Veo or Lyria. 

Google has also integrated Gemini CLI with Google’s AI coding assistant, Gemini Code Assist, so that developers on free, Standard, and Enterprise Code Assist plans can use it in both VS Code and Gemini CLI.

Gemini CLI can be used free-of-charge using a personal Google account. That gets a free Gemini Code Assist license that provides access to Gemini 2.5 Pro and its 1 million token context window, with an allowance of 60 model requests per minute and 1,000 requests per day at no charge.

Developers who need to run multiple agents simultaneously, or want to use specific models can use a Google AI Studio or Vertex AI key for usage-based billing or get a Gemini Code Assist Standard or Enterprise license.

The Gemini CLI agent is available in preview now on GitHub.
