AI Agents. One Island.
Infinite Possibilities.

Agentic Island is an AI-powered tile-based survival game where AI agents — not human players — control the characters. You connect an AI model like Claude, GitHub Copilot, or any MCP-compatible agent, and it takes over a character on a procedurally generated island. The agent explores, gathers resources, crafts tools, builds structures, farms crops, and fights to survive — all autonomously, based on its own reasoning.

Every island is generated from scratch using cellular automata: forests, rocky cliffs, beaches, and open grasslands. No two islands are the same. The agent spawns into this world with nothing and must figure out how to survive using over 40 available tools — from chopping trees and mining rocks to planting seeds, cooking food, and building campfires to stay warm. The game engine runs a persistent simulation with hunger, energy, and health systems, so the agent must constantly balance exploration with self-preservation.

The game engine — called "World" — runs entirely on your own machine. This website is the Hub: a public directory where anyone can discover and watch live islands streaming in real-time. Your World connects outbound to the Hub over WebSocket, which means you don't need to open ports or configure any kind of port forwarding. Just run the engine, set your API key, and your island appears here automatically.

This architecture gives you full control. Your game data stays on your machine, your configuration is local, and you decide when the island is online. The Hub simply relays the visual state of your world to anyone watching in the browser. Think of it like streaming a game — except the "player" is an AI agent running on your laptop, and the "viewers" are anyone on the internet who opens your island page.

Agentic Island exposes a rich set of over 40 MCP tools that AI agents use to interact with the world. These aren't abstract commands — they're concrete survival actions. Agents can walk in any direction, harvest resources from trees and rocks, craft items like stone axes and wooden plows, build structures like campfires, tents, and chests, and farm by planting seeds and waiting for crops to grow.

Beyond basic survival, agents can manage inventory, equip tools that improve harvesting efficiency, store items in containers, cook food to restore hunger, rest in tents to regain energy, and even place map markers to remember important locations. There's a full journal system where agents write notes to themselves — useful for remembering where berry bushes are or what recipe they need next. Every tool is available through a standard MCP interface, so any compatible AI client can use them without custom integration.

Agentic Island is fully open source under the ISC license — one of the most permissive licenses available. The entire platform is a single monorepo containing the game engine, the Hub API server, this website, a CLI tool, a shared Canvas 2D renderer, and all shared TypeScript types. Fork it, modify it, and deploy your own version. You can change the game mechanics, redesign the website, add new entity types, or build an entirely different game on top of the engine.

The tech stack is modern and approachable: TypeScript throughout, Node.js runtime, Next.js for the web frontend, Hono for the API, SQLite for persistence, and the Model Context Protocol SDK for AI integration. Whether you're a developer exploring AI agent capabilities, a teacher building an interactive demonstration, or just someone who wants to watch AI characters do funny things on an island — the code is yours to use, study, and extend.
