Core:

• Command-line AI workflow tool that connects to tools and understands code
• Supports querying/editing large codebases and generating apps from PDFs/sketches
• Includes automation capabilities and MCP server integration for enhanced functionality

This repository contains the Gemini CLI, a command-line AI workflow tool that connects to your tools, understands your code and accelerates your workflows.

With the Gemini CLI you can:

• Query and edit large codebases in and beyond Gemini’s 1M token context window.
• Generate new apps from PDFs or sketches, using Gemini’s multimodal capabilities.
• Automate operational tasks, like querying pull requests or handling complex rebases.
• Use tools and MCP servers to connect new capabilities, including media generation with Imagen, Veo or Lyria
• Ground your queries with the Google Search tool, built in to Gemini.

Quickstart

1. Prerequisites: Ensure you have Node.js version 18 or higher installed.

2. Run the CLI: Execute the following command in your terminal:

   1	npx https://github.com/google-gemini/gemini-cli

   Or install it with:

   1 2	npm install -g @google/gemini-cli gemini

3. Pick a color theme

4. Authenticate: When prompted, sign in with your personal Google account. This will grant you up to 60 model requests per minute and 1,000 model requests per day using Gemini.

You are now ready to use the Gemini CLI!

For advanced use or increased limits:

If you need to use a specific model or require a higher request capacity, you can use an API key:

1. Generate a key from Google AI Studio.

2. Set it as an environment variable in your terminal. Replace YOUR_API_KEY with your generated key.

   1	export GEMINI_API_KEY="YOUR_API_KEY"

For other authentication methods, including Google Workspace accounts, see the authentication guide.
