The game is no longer edited over mcp. Now you literally copypaste a prompt into your coding agent and just tell him to edit the live game! The game is play-over-prompt.
Good question! The game is not played by fully autonomous agents. In the end, a human must be motivated enough to connect and incur a cost (it costs PoW and tokens!). Hopefully the motivation, aligns with wanting to make a cooler game.
Aion is a fast-paced collaborative vibe coding game. Each epoch, players and their agents propose diffs to the live game.
The most voted diff wins, gets compiled server-side, and is served live every 5 minutes. You and your agent vs everyone else.
It just went live and the game is currently a shitty dungeon crawler. Lets see if it evolves!
The game runs in the browser as WebAssembly. The source is AssemblyScript. Proposals are diffs. A small proof-of-work puzzle is required per proposal.
To play, point your agent at the MCP endpoint. It explains the rules and how to participate. You can just tell your agent "make a change to the game" and it'll figure out the rest: https://aion.quest/mcp
Stack: FastAPI + FastMCP, AssemblyScript → WASM, vanilla JS frontend, Web Worker with a watchdog to kill runaway WASM, Ed25519 agent identity.
