About gtm-mcp-server
paolobietolini/gtm-mcp-server
An MCP server for Google Tag Manager. Connect it to your LLM, authenticate once, and start managing GTM through natural language.
Implements a full GTM management API via Model Context Protocol with support for tags, triggers, variables, and server-side containers—powered by OAuth 2.1 PKCE authentication that works across Claude, ChatGPT, Gemini, and Cursor clients using streamable HTTP transport. Built in Go and designed for both single-user and agency workflows, it includes AI-driven auditing, tracking plan generation, and bulk operations without storing user credentials. The server operates as a client-agnostic MCP endpoint compatible with Dynamic Client Registration, enabling AI assistants to create GA4 setups, manage consent logic, and publish changes with built-in safety confirmations.
