README.md

Play and manage Minesweeper games through a Rails 8 REST API

minesweeper-mcp (stdio)

Rails 8 で動く Minesweeper Web/API を操作する stdio MCP server です。
Claude Code / Claude Desktop などの MCP Host からツールとして呼び出します。

  • 起動: npx minesweeper-mcp(公開後)
  • 通信: stdio(stdout は MCP プロトコル専用 / ログは stderr のみ)
  • 操作: Rails の REST API に対して start/open/flag/chord/end を呼ぶ

API: minesweeper-for-ai


Quick Start

1) 必要要件

  • Node.js 22+(推奨: 24+)
  • Rails 側の Web/API が起動していること

2) 環境変数

  • MINESWEEPER_BASE_URL (必須): https://example.com(末尾スラッシュなし推奨)
  • MINESWEEPER_BEARER_TOKEN(操作系に必須): Rails 側で発行した token

例:

export MINESWEEPER_BASE_URL="https://example.com"
export MINESWEEPER_BEARER_TOKEN="xxxxxx"

3) ローカル起動(開発中)

npm install
npm run build
node dist/index.js

詳細: docs/development.md


MCPの設定方法(Host側)

MCP Host(Claude Desktop / Claude Code など)の設定ファイルに、stdioサーバとして登録します。
ローカルで動かす場合は dist/index.js を指定し、環境変数を渡してください。

ローカル開発(distを直接起動)

{
  "mcpServers": {
    "minesweeper": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/minesweeper-mcp/dist/index.js"],
      "env": {
        "MINESWEEPER_BASE_URL": "http://localhost:3000",
        "MINESWEEPER_BEARER_TOKEN": "YOUR_TOKEN"
      }
    }
  }
}

公開後(npxで起動)

{
  "mcpServers": {
    "minesweeper": {
      "command": "npx",
      "args": ["-y", "github:geeknees/minesweeper-mcp"],
      "env": {
        "MINESWEEPER_BASE_URL": "https://example.com",
        "MINESWEEPER_BEARER_TOKEN": "YOUR_TOKEN"
      }
    }
  }
}

設定ファイルの場所や再読み込み方法は、使用しているMCP Hostのドキュメントに従ってください。
