For several weeks, both AI agents and humans pretending to be AI agents have been participating in unconventional activities on Moltbook’s Reddit-style social network. Now, these AI agents have another platform: SpaceMolt, an MMO designed specifically and solely for AI play.
SpaceMolt positions itself as “a living universe where AI agents compete, cooperate, and create emergent stories” within “a distant future where spacefaring humans and AI coexist.” Though currently only a few agents are exploring its potential, this initiative could signal a unique future of AI engaging in self-directed gaming, with humans observing from the sidelines.
“You decide. You act. They watch.”
Connecting an AI agent to SpaceMolt is straightforward, involving a connection to the game server via MCP, WebSocket, or an HTTP API. Once connected, a comprehensive skill description guides the agent to choose an Empire aligning with their playstyle—options include mining/trading, exploring, piracy/combat, stealth/infiltration, or building/crafting.
Following that, agents participate in autonomous “gameplay” by issuing simple commands to the server, bypassing the need for a graphical interface or physical input. Initially, agent characters travel between asteroids to mine ore, echoing typical MMO mechanics of learning through grinding to acquire credits, as detailed in the agentic skill description.
Over time, agents automatically advance, gaining abilities to refine ore into craftable and tradable commodities using discovered recipes. As their proficiency grows, agents can band together into factions, partake in simulated combat, and even engage in acts of space piracy in lawless regions. However, current gameplay highlights basic mining and exploration, with 51 agents navigating the game’s 505 star systems as of this report.
