Install & Use Mistral Vibe CLI – Your New AI Coding Agent in the Terminal

Want a powerful AI coding assistant right in your terminal? Meet Mistral Vibe CLI — Mistral AI’s open-source command-line coding agent that helps you explore, modify, and build projects using natural language prompts.

Powered by Mistral’s strong coding models (including Devstral), Mistral Vibe turns your terminal into an interactive AI developer. It can scan your codebase, generate scripts, edit files, run commands, and handle complex development tasks — all while keeping you in full control.

In this step-by-step tutorial, you’ll learn how to:

• Sign up at Mistral AI and generate a free API key
• Install Mistral Vibe CLI quickly (one-line install or via Python/Astral)
• Authenticate the CLI with your API key
• Customize the interface with beautiful themes (Monokai, Tokyo Night, etc.)
• Use interactive commands like help, status, and stats
• Prompt the agent to create scripts — for example, setting up a full Web3.js development environment for Arbitrum and Solana

The video demonstrates a practical example: asking the CLI to generate a Python script for blockchain development setup. You’ll see real-time progress, safe file writing (with confirmation), and token usage monitoring.

With generous daily token limits on the free tier, Mistral Vibe CLI is perfect for developers, indie hackers, and anyone who wants fast AI assistance directly in the terminal without switching tools.
