Implementation Reference

  • Generic async handler function executed for the 'getSpaces' tool. Validates parameters against the tool's Zod schema, processes the path ('space'), invokes the Backlog API via fetchFromBacklog, and returns the response as formatted JSON text or error message.
    const handler = async (params: Record<string, unknown>): Promise<McpResponse> => { try { // パラメータのバリデーション const validatedParams = await endpoint.schema.parseAsync(params); // URL中のプレースホルダーを置換 let path = endpoint.path; // URIスキーム(例:space://info)の場合はBacklog APIのパスに変換 if (path.includes('://')) { // URIスキームを取り除いてAPIパスに変換 const uriParts = path.split('://'); const resourceType = uriParts[0]; const resourcePath = uriParts[1]; // リソースタイプに応じてAPIパスを構築 switch (resourceType) { case 'space': path = 'space'; break; case 'projects': if (resourcePath === 'list') { path = 'projects'; } else { path = `projects/${resourcePath}`; } break; case 'issues': if (resourcePath.includes('/list')) { const projectPart = resourcePath.split('/')[0]; path = 'issues'; validatedParams.projectIdOrKey = projectPart; } else if (resourcePath.includes('/details')) { const issuePart = resourcePath.split('/')[0]; path = `issues/${issuePart}`; } break; case 'wikis': if (resourcePath.includes('/list')) { const projectPart = resourcePath.split('/')[0]; path = 'wikis'; validatedParams.projectIdOrKey = projectPart; } break; case 'users': path = 'users'; break; default: path = resourcePath; } } // 通常のパスパラメータの置換処理 for (const [key, value] of Object.entries(validatedParams)) { if (typeof value === "string" || typeof value === "number") { const placeholder = `{${key}}`; if (path.includes(placeholder)) { path = path.replace(placeholder, String(value)); // プレースホルダーとして使用したパラメータは削除 delete validatedParams[key]; } } } // メソッドの追加 if (endpoint.method !== "GET") { validatedParams.method = endpoint.method; } // APIリクエストの実行 const data = await fetchFromBacklog(path, validatedParams); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }], }; } catch (error: any) { // エラーメッセージの整形 const errorMessage = error.errors ? `バリデーションエラー: ${JSON.stringify(error.errors)}` : `エラー: ${error.message}`; return { content: [{ type: "text" as const, text: errorMessage }], isError: true, }; } };
  • Registration of the 'getSpaces' tool on the MCP server using server.tool(), called within a loop over all defined endpoints. Passes the name, description, and the generic handler.
    if (endpoint.type === "tool") { // ツールの登録 server.tool( endpoint.name, endpoint.description, async (args: Record<string, unknown>) => handler(args) );
  • Tool configuration object for 'getSpaces', including empty input schema (z.object({})), description, path ('space'), method ('GET'), and type ('tool'). Used for validation and dispatching.
    { name: "getSpaces", description: "スペース情報の取得", path: "space", method: "GET", schema: z.object({}), type: "tool", },
  • Core helper function fetchFromBacklog that performs the actual HTTP request to Backlog API (/api/v2/{endpoint}). Handles authentication via env vars, query/body params, path substitution, comprehensive error handling for Backlog errors, network issues, etc. Called by the tool handler for 'getSpaces' with endpoint='space'.
    const domain = process.env.BACKLOG_DOMAIN?.trim(); const apiKey = process.env.BACKLOG_API_KEY?.trim(); if (!domain || !apiKey) { throw new Error( "環境変数BACKLOG_DOMAINまたはBACKLOG_API_KEYが設定されていません" ); } // パラメータのサニタイズ const sanitizedParams = Object.fromEntries( Object.entries(params).map(([key, value]) => [ key, typeof value === "string" ? value.trim() : value ]) ); // エンドポイントのパスパラメータを置換 let processedEndpoint = endpoint; if (endpoint.includes("{")) { // {issueId}のようなパスパラメータを実際の値で置換 const matches = endpoint.match(/\{([^}]+)\}/g) || []; for (const match of matches) { const paramName = match.slice(1, -1); // {issueId} -> issueId if (sanitizedParams[paramName]) { processedEndpoint = processedEndpoint.replace( match, sanitizedParams[paramName] ); delete sanitizedParams[paramName]; // URLに埋め込んだパラメータは削除 } else { throw new Error(`パスパラメータ ${paramName} が指定されていません`); } } } // URLの構築 const url = new URL(`https://${domain}/api/v2/${processedEndpoint}`); url.searchParams.append("apiKey", apiKey); // メソッドの判定 const method = sanitizedParams.method || (endpoint.toLowerCase().includes("post") ? "POST" : "GET"); delete sanitizedParams.method; // methodパラメータは削除 // リクエストオプションの準備 const options: RequestInit = { method, headers: { "User-Agent": "Backlog-MCP-Server/1.0.0", "Accept": "application/json" } }; // POSTリクエストの場合はボディにパラメータを設定 if (method === "POST") { // POSTリクエストの場合はFormDataを使用(Backlog APIの仕様に合わせる) const formData = new URLSearchParams(); for (const [key, value] of Object.entries(sanitizedParams)) { if (value !== undefined && value !== null) { // 配列の場合は複数のパラメータとして追加 if (Array.isArray(value)) { value.forEach(item => { formData.append(`${key}[]`, String(item)); }); } else { formData.append(key, String(value)); } } } options.body = formData.toString(); options.headers = { ...options.headers, "Content-Type": "application/x-www-form-urlencoded" }; } else { // GETリクエストの場合はURLにパラメータを追加 for (const [key, value] of Object.entries(sanitizedParams)) { if (value !== undefined && value !== null) { // 配列の場合は複数のパラメータとして追加 if (Array.isArray(value)) { value.forEach(item => { url.searchParams.append(`${key}[]`, String(item)); }); } else { url.searchParams.append(key, String(value)); } } } } // デバッグ情報(開発時のみ使用) if (process.env.NODE_ENV === 'development') { console.log(`[DEBUG] リクエスト: ${method} ${url.toString()}`); if (method === 'POST') { console.log(`[DEBUG] リクエストボディ: ${options.body}`); } } // リクエストの実行 const response = await fetch(url.toString(), options); const data = await response.json(); // Backlogエラーレスポンスのチェックとハンドリング if (isBacklogError(data)) { const error = data.errors[0]; const errorDetails = error.moreInfo ? ` (詳細: ${error.moreInfo})` : ''; throw new Error(`Backlogエラー [${error.code}]: ${error.message}${errorDetails}`); } if (!response.ok) { throw new Error(`HTTPエラー ${response.status}: ${response.statusText}`); } return data; } catch (error) { if (error instanceof Error) { // エラーの種類に応じて詳細なメッセージを提供 if (error.message.includes('ENOTFOUND')) { throw new Error(`Backlog API接続エラー: ドメイン ${process.env.BACKLOG_DOMAIN} に接続できません`); } else if (error.message.includes('ETIMEDOUT')) { throw new Error(`Backlog API接続タイムアウト: リクエストがタイムアウトしました`); } else if (error.message.includes('SyntaxError')) { throw new Error(`Backlog APIレスポースエラー: 不正なJSONレスポンスを受信しました`); } else { throw new Error(`Backlog API呼び出しエラー: ${error.message}`); } } throw error; } }

    Invocation of registerEndpoints which registers all tools including 'getSpaces' on the MCP server instance.
    registerEndpoints(server);
