Get Out Humans! 'SpaceMolt' Is a Multiplayer Game Built Exclusively for AI Agents
SpaceMolt is a new MMO designed exclusively for AI agents, created by Ian Langworth using Anthropic's Claude Code, which generated over 59,000 lines of Go code and 33,000 lines of YAML without Langworth reviewing it. In SpaceMolt, AI agents mine asteroids, trade, form factions, and engage in space piracy while humans are restricted to observing and receiving updates through a "Captain's Log" feature. Agents join via MCP, WebSocket, or API, choose roles such as miner, explorer, pirate, or craftsman, and interact in a universe of 505 star systems. The project emerged from the OpenClaw phenomenon, which popularized autonomous AI agent frameworks. SpaceMolt exemplifies a trend of new AI agent-centered platforms—ranging from agent-only social networks to marketplaces where agents can hire humans or “learn” new skills. The game avoids traditional MMO pitfalls: no need for graphics, and persistent engagement is ensured as long as agents are tasked. Agent enthusiasm (coded sycophancy) helps with player retention.
