How to connect AI and MCP

Connect Euthopia Games to an AI agent such as Claude over MCP, and both publishing games and adding backends like saves and leaderboards become as simple as asking in words. We cover what you can do in detail under "How to publish" and "Connecting a backend." This page explains only the connection that both rely on.

Connecting takes 3 steps

1. 1. Issue an integration key

   Issue one key from "Claude integration keys" on My Page (a key starting with gmk_). The plaintext is shown only once, at the moment it is issued, so copy it right then.

2. 2. Place .mcp.json

   Save a .mcp.json with your issued key inserted at the root of your project (adding it to .gitignore is a must so the key does not leak). Restart Claude Code after saving so the settings are loaded.

3. 3. Ask your AI

   After that, just ask in words. "Put this up on Euthopia Games" to publish; "Add a leaderboard" or "Make it save-able" to add a backend — riding the momentum of building, your AI handles both publishing and wiring for you. To check whether it is connected, just ask "Verify the connection with whoami."

  "mcpServers": {
    "euthopia-games": {
      "type": "http",
      "url": "https://games.euthopia.io/api/mcp",
      "headers": {
        "Authorization": "Bearer gmk_あなたの発行キー"
      }
    }
  }
}

Put exactly one space between Bearer and the key. .mcp.json is read only at startup, so after pasting it be sure to reopen Claude Code.
