Implementation Reference

• src/gcp/auth.ts:38-131 (handler)

  The core handler function for the 'gcp_auth_status' tool. It checks GCP authentication using checkGcloudAuth, fetches config and accounts if needed, and returns formatted output in text or JSON.

  export async function gcpAuthStatus(args: GcpAuthStatusArgs) {
    try {
      const authStatus = await checkGcloudAuth();
  
      if (!authStatus.authenticated) {
        return {
          content: [
            {
              type: 'text',
              text: formatError(authStatus.error),
            },
          ],
          isError: true,
        };
      }
  
      // Get additional configuration
      const configResult = await executeGcloud('config list --format=json', 10000);
      let config: any = {};
      try {
        config = JSON.parse(configResult.stdout || '{}');
      } catch {
        config = {};
      }
  
      // Get all accounts if requested
      let allAccounts: string[] = [];
      if (args.show_all_accounts) {
        try {
          const accountsResult = await executeGcloud('auth list --format="value(account)"', 10000);
          allAccounts = accountsResult.stdout.trim().split('\n').filter(Boolean);
        } catch {
          // Ignore errors
        }
      }
  
      const result = {
        authenticated: true,
        activeAccount: authStatus.account,
        project: authStatus.project,
        region: config.compute?.region || 'not set',
        zone: config.compute?.zone || 'not set',
        allAccounts: args.show_all_accounts ? allAccounts : undefined,
      };
  
      if (args.format === 'json') {
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify(result, null, 2),
            },
          ],
        };
      }
  
      const lines = [
        '🔑 GCP 인증 상태',
        '',
        `✅ 인증됨`,
        `👤 계정: ${result.activeAccount}`,
        `📁 프로젝트: ${result.project || '(설정 안됨)'}`,
        `🌍 리전: ${result.region}`,
        `📍 존: ${result.zone}`,
      ];
  
      if (args.show_all_accounts && allAccounts.length > 1) {
        lines.push('', '📋 모든 인증된 계정:');
        allAccounts.forEach((account) => {
          const isActive = account === result.activeAccount;
          lines.push(`  ${isActive ? '→' : ' '} ${account}${isActive ? ' (활성)' : ''}`);
        });
      }
  
      return {
        content: [
          {
            type: 'text',
            text: lines.join('\n'),
          },
        ],
      };
    } catch (error: any) {
      return {
        content: [
          {
            type: 'text',
            text: formatError(error),
          },
        ],
        isError: true,
      };
    }
  }

• src/gcp/auth.ts:4-36 (schema)

  Tool schema definition including name, description, annotations, and input schema for parameters show_all_accounts and format. Also defines the TypeScript interface for function arguments.

  export const gcpAuthStatusDefinition = {
    name: 'gcp_auth_status',
    description: '인증 상태|로그인 확인|계정 정보|auth status|whoami - GCP 인증 상태와 계정 정보를 확인합니다',
    annotations: {
      title: 'GCP 인증 상태 확인',
      readOnlyHint: true,
      destructiveHint: false,
      idempotentHint: true,
      openWorldHint: true,
    },
    inputSchema: {
      type: 'object' as const,
      properties: {
        show_all_accounts: {
          type: 'boolean',
          description: '모든 인증된 계정 표시 (기본: false)',
          default: false,
        },
        format: {
          type: 'string',
          enum: ['text', 'json'],
          description: '출력 형식 (기본: text)',
          default: 'text',
        },
      },
      required: [],
    },
  };
  
  interface GcpAuthStatusArgs {
    show_all_accounts?: boolean;
    format?: 'text' | 'json';
  }

• src/index.ts:77-89 (registration)

  Adds gcpAuthStatusDefinition to the tools array returned by ListToolsRequestHandler, registering the tool with the MCP server.

  const tools = [
    gcpSetupDefinition,
    gcpLogsReadDefinition,
    gcpRunStatusDefinition,
    gcpRunLogsDefinition,
    gcpSqlQueryDefinition,
    gcpSqlProxyDefinition,
    gcpStorageListDefinition,
    gcpSecretListDefinition,
    gcpAuthStatusDefinition,
    gcpServicesListDefinition,
    gcpBillingInfoDefinition,
  ];

• src/index.ts:227-228 (registration)

  In the CallToolRequestHandler switch statement, dispatches calls to the gcp_auth_status tool by invoking the gcpAuthStatus handler function.

  case 'gcp_auth_status':
    return await gcpAuthStatus(args as any) as CallToolResult;
