Google Tag Manager MCP Server

Instructions

Implementation Reference

• src/gtm-client.js:79-86 (handler)

  The core handler function in GTMClient class that creates a new container by calling the Google Tag Manager API's accounts.containers.create method, after ensuring the user is authenticated.

  async createContainer(accountId, containerData) {
    await this.ensureAuth();
    const response = await this.tagmanager.accounts.containers.create({
      parent: `accounts/${accountId}`,
      requestBody: containerData
    });
    return response.data;
  }

• src/index.js:962-977 (registration)

  Registers the 'create_container' tool handler in the MCP server's CallToolRequestSchema switch statement, mapping tool arguments to the GTMClient.createContainer method call.

  case 'create_container':
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(
            await this.gtmClient.createContainer(args.accountId, {
              name: args.name,
              usageContext: args.usageContext,
            }),
            null,
            2
          ),
        },
      ],
    };

• src/index.js:115-139 (schema)

  Defines the tool schema including name, description, and inputSchema for 'create_container' in the ListToolsRequestSchema response.

    name: 'create_container',
    description: '新しいコンテナを作成します',
    inputSchema: {
      type: 'object',
      properties: {
        accountId: {
          type: 'string',
          description: 'アカウントID',
        },
        name: {
          type: 'string',
          description: 'コンテナ名',
        },
        usageContext: {
          type: 'array',
          items: {
            type: 'string',
            enum: ['web', 'android', 'ios', 'amp'],
          },
          description: '使用コンテキスト（例: ["web"]）',
        },
      },
      required: ['accountId', 'name', 'usageContext'],
    },
  },
