Duo Agent Platformの[MCP](https://about.gitlab.com/topics/ai/model-context-protocol/)サポートにより、JiraをはじめMCPに対応したあらゆるツールを、AIを活用した開発環境に直接接続できるようになりました。課題の照会、チケットの更新、ワークフローの同期——すべて自然言語で、IDEを離れることなく実行できます。\n\n## この記事で学べること\n\nこのチュートリアルでは、以下の内容を解説します。\n\n* **Jira/Atlassian OAuthアプリケーションのセットアップ** — セキュアな認証の設定\n* **GitLab Duo Agent PlatformのMCPクライアントとしての設定** — 接続の構成\n* **3つの実践的なユースケース** — 実際のワークフローのデモ\n\n## 前提条件\n\n開始する前に、以下の要件を満たしていることをご確認ください。\n\n| 要件 | 詳細 |\n| ---- | ----- |\n| **GitLabインスタンス** | Duo Agent Platformが有効なGitLab 18.8以降 |\n| **Jiraアカウント** | OAuthアプリケーションを作成できる管理者権限を持つJira Cloudインスタンス |\n| **IDE** | GitLab Workflow拡張機能がインストールされたVisual Studio Code |\n| **MCPサポート** | GitLabでMCPサポートが有効化済み |\n\n\n## アーキテクチャの概要\n\nGitLab Duo Agent Platformは**MCPクライアント**として機能し、Atlassian MCPサーバーに接続してJiraのプロジェクト管理データにアクセスします。Atlassian MCPサーバーは認証を処理し、自然言語のリクエストをAPI呼び出しに変換して、構造化されたデータをGitLab Duo Agent Platformに返します。このプロセス全体を通じて、セキュリティと監査管理が維持されます。\n\n## パート1：Jira OAuthアプリケーションの設定\n\nGitLab Duo Agent PlatformをJiraインスタンスに安全に接続するには、Atlassian Developer ConsoleでOAuth 2.0アプリケーションを作成する必要があります。これにより、GitLabのMCPサーバーにJiraデータへの認可されたアクセス権が付与されます。\n\n### セットアップ手順\n\n手動で設定する場合は、以下の手順に従ってください。\n\n1. **Atlassian Developer Consoleにアクセス**\n\n   * [developer.atlassian.com/console/myapps](https://developer.atlassian.com/console/myapps)にアクセスします。\n\n   * Atlassianアカウントでサインインします。\n\n2. **新しいOAuth 2.0アプリを作成**\n\n   * **Create** → **OAuth 2.0 integration** をクリックします。\n\n   * アプリ名を入力します（例：「gitlab-dap-mcp」）。\n\n   * 利用規約に同意し、**Create** をクリックします。\n\n3. **権限の設定**\n\n   * 左サイドバーの **Permissions** に移動します。\n\n   * **Jira API** を追加し、以下のスコープを設定します。\n\n     * `read:jira-work` — 課題、プロジェクト、ボードの読み取り\n\n     * `write:jira-work` — 課題の作成と更新\n\n     * `read:jira-user` — ユーザー情報の読み取り\n\n4. **認可の設定**\n\n   * 左サイドバーの **Authorization** に移動します。\n\n   * お使いの環境のコールバックURLを追加します（`https://gitlab.com/oauth/callback`）。\n\n   * 変更を保存します。\n\n5. **認証情報の取得**\n\n   * **Settings** に移動します。\n\n   * **Client ID** と **Client Secret** をコピーします。\n\n   * これらの認証情報はMCP設定に必要なため、安全な場所に保管してください。\n\n\n### インタラクティブウォークスルー：Jira OAuthのセットアップ\n\n以下の画像をクリックして開始してください。\n\n\n[![Jira OAuth setup tour](https://res.cloudinary.com/about-gitlab-com/image/upload/v1772644850/wnzfoq43nkkfmgdqldmr.png)](https://gitlab.navattic.com/jira-oauth-setup)\n\n\n## パート2：GitLab Duo Agent PlatformのMCPクライアントの設定\n\nOAuth認証情報の準備ができたら、GitLab Duo Agent PlatformをAtlassian MCPサーバーに接続するための設定を行います。\n\n### MCP設定ファイルの作成\n\nGitLabプロジェクトの `.gitlab/duo/mcp.json` にMCP設定ファイルを作成します。\n\n\n```json\n{\n  \"mcpServers\": {\n    \"atlassian\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.atlassian.com/v1/mcp\",\n      \"auth\": {\n        \"type\": \"oauth2\",\n        \"clientId\": \"YOUR_CLIENT_ID\",\n        \"clientSecret\": \"YOUR_CLIENT_SECRET\",\n        \"authorizationUrl\": \"https://auth.atlassian.com/oauth/authorize\",\n        \"tokenUrl\": \"https://auth.atlassian.com/oauth/token\"\n      },\n      \"approvedTools\": true\n    }\n  }\n}\n```\n\n`YOUR_CLIENT_ID` と `YOUR_CLIENT_SECRET` は、パート1で生成した認証情報に置き換えてください。\n\n### GitLabでMCPを有効化\n\n1. **グループ設定** → **GitLab Duo** → **Configuration** に移動します。\n2. 「Allow external MCP tools」にチェックが入っていることを確認します。\n\n### 接続の確認\n\nVS CodeでプロジェクトをひらいてGitLab Duo Agent Platformのチャットで次のように入力してください。\n\n```text\nWhat MCP tools do you have access to?\n```\n\n次に\n\n```text\nTest the MCP JIRA configuration in this project\n```\n\nこの時点で、IDEからAtlassian MCPウェブサイトにリダイレクトされ、アクセスの承認を求められます。\n\n![Redirect to MCP Atlassian website](https://res.cloudinary.com/about-gitlab-com/image/upload/v1772643461/z5acqjgguh0damnnde9g.png

MCPダッシュボードによる確認\n\nGitLabは、IDEに組み込みの**MCPダッシュボード**も提供しています。\n\nVS CodeまたはVSCodiumで、コマンドパレット（macOSでは `Cmd+Shift+P`、Windows/Linuxでは `Ctrl+Shift+P`）をひらいて **「GitLab: Show MCP Dashboard」** を検索してください。ダッシュボードは新しいエディタータブで表示され、以下の情報を確認できます。\n\n* 設定済みの各MCPサーバーの**接続ステータス**\n* サーバーが公開している**利用可能なツール**（例：`jira_get_issue`、`jira_create_issue`）\n* **サーバーログ** — リアルタイムで呼び出されているツールを確認可能\n\n![MCP
