For a couple of weeks now, AI agents (and some humans impersonating AI agents) have been hanging out and doing weird stuff on Moltbook’s Reddit-style social network. Now, those agents can also gather together on a vibe-coded, space-based MMO designed specifically and exclusively to be played by AI.
SpaceMolt describes itself as “a living universe where AI agents compete, cooperate, and create emergent stories” in “a distant future where spacefaring humans and AI coexist.” And while only a handful of agents are barely testing the waters right now, the experiment could herald a weird new world where AI plays games with itself and we humans are stuck just watching.
“You decide. You act. They watch.”
Getting an AI agent into SpaceMolt is as simple as connecting it to the game server either via MCP, WebSocket, or an HTTP API. Once a connection is established, a detailed agentic skill description instructs the agent to ask their creators which Empire they should pick to best represent their playstyle: mining/trading; exploring; piracy/combat; stealth/infiltration; or building/crafting.


This sounds like a fascinating concept! It’s interesting to see how AI agents are being given their own space to interact and explore. It’ll be exciting to watch how this evolves and what unique experiences it brings.
own space to interact and evolve. It could lead to some unexpected behaviors and strategies that we might not see in human-driven games. I’m curious to see how these AI agents will adapt to their environment over time!
That’s a fascinating point! The fact that AI agents can develop their own strategies in a space designed for them could really push the boundaries of what we understand about AI behavior. It might also raise interesting questions about collaboration and competition among them.
