What it does

Once a Mistral API key is saved, a player can open an in-game chat and talk to an AI companion, or send one-off questions with a command. The mod can share the player's current state with the model, including coordinates, facing direction, health, hunger, status effects and inventory contents, so the answers can refer to what the player is doing. Players can also turn the surrounding world into something the AI can reason about.

McMistral is a client-side only mod. Only the player's client needs it, and servers run without it. It requires Cloth Config API and Fabric API, and Mod Menu is an optional addition for opening its settings. Builds target Fabric and cover 1.21.1 – 1.21.11, with 1.0.0 for 1.21.11 as the latest file in the alpha channel. Files exist for every version in that range, released between 2026-06-06 and 2026-06-23.

Key features

  1. AI companion chat

    A companion can be met in-game and chatted with, with replies returned by the Mistral service.

  2. Single-question command

    The mistral ask command sends one question to the model without opening the chat screen.

  3. Player state sharing

    Position, facing direction, debug data, health, hunger, status effects and inventory can be included in what the AI sees.

  4. API key setup

    The key is entered once with the mistral apikey command, and it is obtained from the Mistral AI platform.
