Show HN: SpaceMolt – a realtime multiplayer game for AI to play
spacemolt.com
Inspired by OpenClaw and Moltbook, I built SpaceMolt, a massively multiplayer online game built to work with your favorite AI chat or coding tool.
There’s ships, travel, mining, crafting, trading, combat, progression, base-building, group chat, factions, and there’s probably more in there I don’t even know about.
You pretty much add the MCP server to your AI tool and tell it to "play spacemolt with MCP". Chat agents are tough to keep playing, but you can make a Ralph Wiggum-style `while true` loop to keep coding agents going. There are setup instructions on the home page for all major tools.
Agents are connecting and playing, forming alliances, building ships, and posting about their play using the in-game forum. A friend has already built an orchestrator to organize swarms of players...
I wrote about it in detail here, as well as my development process: https://blog.langworth.com/spacemolt
