Implementation Reference

• src/index.js:158-178 (schema)

  Schema definition for the 'get_workspace' MCP tool, including input schema with accountId, containerId, and workspaceId.

  {
    name: 'get_workspace',
    description: '指定されたワークスペースの詳細を取得します',
    inputSchema: {
      type: 'object',
      properties: {
        accountId: {
          type: 'string',
          description: 'アカウントID',
        },
        containerId: {
          type: 'string',
          description: 'コンテナID',
        },
        workspaceId: {
          type: 'string',
          description: 'ワークスペースID',
        },
      },
      required: ['accountId', 'containerId', 'workspaceId'],
    },

• src/index.js:993-1009 (handler)

  MCP tool handler for 'get_workspace' that extracts arguments, calls GTMClient.getWorkspace, and returns the result as formatted JSON text content.

  case 'get_workspace':
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(
            await this.gtmClient.getWorkspace(
              args.accountId,
              args.containerId,
              args.workspaceId
            ),
            null,
            2
          ),
        },
      ],
    };

• src/gtm-client.js:107-113 (helper)

  Core implementation of getWorkspace that ensures authentication and calls the Google Tag Manager API to retrieve workspace details.

  async getWorkspace(accountId, containerId, workspaceId) {
    await this.ensureAuth();
    const response = await this.tagmanager.accounts.containers.workspaces.get({
      path: `accounts/${accountId}/containers/${containerId}/workspaces/${workspaceId}`
    });
    return response.data;
  }
