  • lawNum (必須): 法令番号

インストール

npm経由でインストール(推奨)

npx hourei-mcp-server

ローカル開発

git clone 
cd hourei-mcp-server
npm install

使用方法

MCPクライアントでの設定

Claude Desktopなどのクライアントの設定ファイル(~/Library/Application Support/Claude/claude_desktop_config.json)に以下を追加:

{
"mcpServers": {
"hourei": {
"command": "npx",
"args": ["-y", "hourei-mcp-server"]
}
}
}

設定後、Claude Desktopを再起動してください。

Cursor AI での設定

Cursorの設定ファイル(.cursor/mcp_config.json または設定画面)に以下を追加:

{
"mcpServers": {
"hourei": {
"command": "npx",
"args": ["-y", "hourei-mcp-server"]
}
}
}

ChatGPT Desktop での設定

ChatGPTでは、MCPサーバーのURLを指定する形式で設定します。

オプション1: npxコマンドで実行(他のクライアントと同じ)

{
"mcpServers": {
"hourei": {
"command": "npx",
"args": ["-y", "hourei-mcp-server"]
}
}
}

オプション2: URL形式で指定(SSEサーバー経由)

SSE対応サーバーを別途立ち上げた場合:

{
"mcpServers": {
"hourei": {
"url": "http://localhost:3000/sse"
}
}
}

または、リモートサーバーにデプロイした場合:

{
"mcpServers": {
"hourei": {
"url": "https://your-server.com/sse"
}
}
}

注意: 現在のバージョン(v1.0.5)はstdio接続のみ対応しています。URL形式で使用する場合は、別途SSE対応のラッパーサーバーが必要です。
