Implementation Reference

• src/server.ts:2171-2193 (handler)

  Handler implementation for the 'get_coupon_info' tool. Validates credentials, retrieves the coupon ID from arguments, fetches coupon details from Sakura Cloud API endpoint `/coupon/{couponId}`, and returns the JSON response.

  } else if (request.params.name === 'get_coupon_info') {
    try {
      validateCredentials();
      
      const couponId = request.params.arguments?.couponId as string;
      if (!couponId) {
        throw new Error('Coupon ID is required');
      }
      
      const couponInfo = await fetchFromSakuraCloud(`/coupon/${couponId}`);
      
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(couponInfo, null, 2)
          }
        ]
      };
    } catch (error) {
      console.error('Error calling tool:', error);
      throw error;
    }

  },

• src/server.ts:20-72 (helper)

  Shared helper function `fetchFromSakuraCloud` used by the tool handler to make authenticated HTTPS requests to Sakura Cloud API.

  async function fetchFromSakuraCloud(path: string, isPublicAPI: boolean = false, zone: string = DEFAULT_ZONE, method: string = 'GET', bodyData?: any): Promise<any> {
    return new Promise((resolve, reject) => {
      const basePath = isPublicAPI ? '/cloud/api/cloud/1.1' : `/cloud/zone/${zone}/api/cloud/1.1`;
      
      const options = {
        hostname: 'secure.sakura.ad.jp',
        port: 443,
        path: `${basePath}${path}`,
        method: method,
        headers: {
          'Accept': 'application/json',
          'Authorization': '',
          'Content-Type': 'application/json'
        }
      };
      
      // Add authorization for non-public APIs
      if (!isPublicAPI) {
        options.headers['Authorization'] = `Basic ${Buffer.from(`${SACLOUD_API_TOKEN}:${SACLOUD_API_SECRET}`).toString('base64')}`;
      }
  
      const req = https.request(options, (res) => {
        let data = '';
        
        res.on('data', (chunk) => {
          data += chunk;
        });
        
        res.on('end', () => {
          try {
            if (data) {
              const parsedData = JSON.parse(data);
              resolve(parsedData);
            } else {
              resolve({});
            }
          } catch (err) {
            reject(new Error(`Failed to parse response: ${err}`));
          }
        });
      });
      
      req.on('error', (error) => {
        reject(error);
      });
      
      if (bodyData && (method === 'POST' || method === 'PUT')) {
        req.write(JSON.stringify(bodyData));
      }
      
      req.end();
    });
  }
