I just saw a pic-to-Braille conversion bot on Reddit, and your comment made me wonder if something similar could be built for blind Minecraft players. So far, I'm not aware of open source Minecraft-alikes that exposes the game purely through an API, though an open modding API like Minetest's [2] could probably be leveraged.
Googling around for this information leads to a lot of dead ends talking about the in-game Blindness effect, and I'm not a domain expert in what blind gamers would want to see, anyways. But it would be really cool to see the blind community add new dimensions to current game genres through game interaction APIs (though managing that and botting using the APIs would be an open problem).
