Implementation Reference

• src/index.js:1430-1447 (handler)

  The handler function for the 'get_trigger' MCP tool. It extracts parameters from the request, calls gtmClient.getTrigger, stringifies the result as JSON, and returns it as text content.

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

• src/index.js:379-403 (schema)

  The schema definition for the 'get_trigger' tool, including name, description, and input schema requiring accountId, containerId, workspaceId, and triggerId.

  {
    name: 'get_trigger',
    description: '指定されたトリガー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',
        },
        triggerId: {
          type: 'string',
          description: 'トリガーID',
        },
      },
      required: ['accountId', 'containerId', 'workspaceId', 'triggerId'],
    },

• src/gtm-client.js:229-235 (helper)

  The core helper method in GTMClient that performs the actual API call to retrieve trigger details using the Google Tag Manager API.

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