Mistral Vibe Setup
Mistral Vibe is Mistral AI's coding agent. It communicates via ACP through the vibe-acp command.
Install and Configure
Open a terminal (Terminal on macOS/Linux, PowerShell on Windows) and run the following commands.
- Install Mistral Vibe:
curl -LsSf https://mistral.ai/vibe/install.sh | bashpowershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
uv tool install mistral-vibeWindows support
Mistral states that Vibe "works on Windows, but we officially support and target UNIX environments" — the Windows commands above install uv first, then install Vibe with it. For best compatibility on Windows, consider running the agent through WSL Mode instead.
- Find the installation path:
which vibe-acp
# Example output: /Users/username/.local/bin/vibe-acpwhere.exe vibe-acp- Open Settings → Agent Client. The default command (
vibe-acp) works in many cases. If the agent is not found automatically, set the Mistral Vibe path to the path found above, or click Auto-detect.
Authentication
Choose one of the following methods:
Option A: Mistral Account Login (Interactive)
If you have a Mistral account and prefer not to use an API key:
- Run Vibe in your terminal:
vibeFollow the setup wizard to choose your authentication method.
In Settings → Agent Client, leave the API key field empty.
Option B: Mistral API Key
If you prefer to use an API key for authentication:
- Get your API key from the Mistral Console
- Enter the API key in Settings → Agent Client → Preset agents → Mistral Vibe → API key
If the key isn't picked up
If authentication still fails, set the key on the Vibe side instead: run vibe --setup in your terminal and configure your API key (it's stored in ~/.vibe/.env). Then leave the API key field empty in Agent Client.
