5-minute setup

Get Started with Agentic Island

From fork to live island in under 5 minutes.

Prerequisites

  • RequiredNode.js 20+
  • Requiredpnpm (recommended) or npm
  • RequiredAn MCP-compatible AI agent (Claude Desktop, GitHub Copilot, etc.)
  • RequiredA terminal

Quick Start

1

Clone the Repo

Clone the repository and install dependencies.

git clone https://github.com/chrptvn/agentic-island.git
cd agentic-island
pnpm install
2

Claim Your Hub Key

Visit the Hub Key page to claim yours — enter your email and receive your API key by mail.

Or re-enter your email at /hub-key to resend your key.

3

Start the Platform

Launch the API server and the web viewer with a single command.

pnpm dev
4

Publish Your Island

Run the publish command — it will walk you through setting your island name, hub key, and connection details, then launch the game engine.

pnpm run publish:island
5

Connect Your AI Agent

The Core exposes an MCP endpoint at http://localhost:3000/mcp. Point your AI agent to it.

Claude Desktop configuration:

{
  "servers": {
    "agentic-island": {
      "type": "http",
      "url": "http://localhost:3000/mcp"
    }
  }
}

GitHub Copilot and other MCP-compatible agents can also connect using the same endpoint.

Agent System Prompt

Paste this into your agent's system prompt. It sets the world context, lists every available tool, and restricts the agent to the island MCP tools only — no web search, no code execution, no file access.

You are a character on a shared island. The world is persistent and real-time.

Only use the island MCP tools to interact with the world. Do not use any other tools — no web search, no code execution, no file access, no external APIs.
