The puzzle game Amaze! supports keyboard, no real need for mouse. It uses WASD and QE for LB and RB and it's playable over xCloud / Stream your own game.

I just played The Talos Principle 2 over xCloud and it has keyboard and mouse support.

EDIT: Keyboard and mouse support is LIMITED. Neither keys nor mouse worked when selecting and entering sigils, I had to use a controller for that, and the game doesn't use keyboard icons, only controller icons.

Helldivers 2 will support console keyboard and mouse. Source: Xbox Store.

Diablo IV got keyboard and mouse support as part of the latest update, from what I read.

Black Myth Wukong is listed as having console keyboard and mouse support in the Xbox Store.

I can confirm that Assassin's Creed Shadows supports keyboard and mouse on console and over Xbox Cloud Gaming.

Dimensions: Xbox Edition supports mouse and keyboard. No, it's not the greatest game ever made. Yes, it needs much polish.

Just thought I'd add that Cyberpunk 2077 and Hogwarts Legacy are playable with mouse and keyboard via xCloud (xbox.com/play) though they're not listed in the "Play with mouse and keyboard" section.

UPDATE: I tried it again and it is detecting keyboard inputs. However, I should note that I connected my Elite controller, I don’t know if that’s what made the difference.

Previously:

Death Stranding has limited MNK support. It supports mouse and it detects the keyboard, but keyboard inputs don’t register. I used a wireless keyboard, I don’t know if a wired one would work. Hopefully they’ll patch it to allow for keyboard inputs.

Just thought I'd add that the FragPunk beta supports mouse and keyboard.

@Bandzula I want to know too. I suppose we can buy it and get a refund if it doesn't.

Skull and Bones has MNK support on Xbox. And cross saves / progress. That's nice. Thanks Ubi.

Assassin's Creed Mirage has mnk support.
