GTM MCP Server

GTM MCP Server is an open-source Model Context Protocol (MCP) server that connects MCP clients to the Google Tag Manager (GTM) API. It enables advanced programmatic access and automation for GTM accounts, containers, workspaces, tags, triggers, variables, folders, zones, environments, and more. The tool supports both individual Google OAuth sign-in and service account authentication for automated, self-hosted workflows, making it suitable for marketers, developers, automation engineers, and anyone needing programmatic or AI-based GTM management, auditing, or customization.
