Implementation Reference

• src/server.ts:941-952 (registration)

  Registration of the 'get_router_info' tool in the ListToolsRequestSchema handler, including its name, description, and input schema.

  name: 'get_router_info',
  description: 'Get detailed information about a specific router',
  inputSchema: {
    type: 'object',
    properties: {
      routerId: {
        type: 'string',
        description: 'The ID of the router to retrieve'
      }
    },
    required: ['routerId']
  }

• src/server.ts:943-951 (schema)

  Input schema definition for the get_router_info tool.

  inputSchema: {
    type: 'object',
    properties: {
      routerId: {
        type: 'string',
        description: 'The ID of the router to retrieve'
      }
    },
    required: ['routerId']

• src/server.ts:1742-1764 (handler)

  The main handler logic for executing the get_router_info tool within the CallToolRequestSchema handler. It validates credentials, extracts routerId from arguments, fetches data from Sakura Cloud API endpoint `/internet/${routerId}`, and returns the JSON response.

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

• src/server.ts:20-72 (helper)

  Core helper function fetchFromSakuraCloud used by get_router_info to make HTTPS requests to Sakura Cloud API, handling authentication, JSON parsing, and errors.

  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();
    });
  }

• src/server.ts:125-129 (helper)

  Helper function validateCredentials called by get_router_info handler to ensure API credentials are set.

  function validateCredentials(): void {
    if (!SACLOUD_API_TOKEN || !SACLOUD_API_SECRET) {
      throw new Error('Missing API credentials. Set SACLOUD_API_TOKEN and SACLOUD_API_SECRET environment variables.');
    }
  }
