Mistral Vibe, also documented as Vibe Code, is Mistral AI's open-source CLI coding assistant. It supports interactive terminal use, non-interactive programmatic mode, VS Code, Vibe Code Web, MCP, skills, custom agents, hooks, and ACP.
Key capabilities
CLI and programmatic mode - The vibe CLI supports interactive mode and non-interactive use through vibe --prompt, including JSON and streaming output options.
MCP support - MCP servers are configured in config.toml under mcp_servers, with http, streamable-http, and stdio transports.
Extensions - Vibe supports skills, custom agents, hooks, and ACP through vibe-acp.
Multiple surfaces - Mistral positions Vibe across CLI, VS Code extension, and Vibe Code Web. The web surface is cloud sandboxed and should not be used for tasks requiring local files, secrets, or services.
Autonomy level
Level 3 (supervised agent): terminal coding workflows with programmatic modes and extension points.
Strengths
- Open-source Mistral-backed CLI coding assistant
- Can work with local models or compatible API keys
- MCP, skills, custom agents, hooks, and ACP make it extensible
Limitations
- Windows works, but Mistral officially targets Unix environments
- Vibe Code Web is cloud sandboxed and not suitable for local-file or secret-dependent work
- DevThrottle still needs empirical terminal-mode and transcript testing
