Samarth Gtm MCP

An open-source Model Context Protocol (MCP) server that lets AI assistants such as Claude Desktop, Claude Code and Cursor work with Google Tag Manager and GA4. It covers the full GTM API v2 surface (100+ tools, including server-side containers), the GA4 Admin and Data APIs, a built-in implementation audit, and a second server that crawls a website to check its tags and Consent Mode v2 setup. Built by Samarth…. Its 40 documented tools cover containers, workspace, tags, triggers.

People who work with containers, workspace and tags and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Code

claude mcp add samarthanalytics-sj-samarth-analytics-mc -- npx -y samarth-gtm-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "samarthanalytics-sj-samarth-analytics-mc": {
      "command": "npx",
      "args": [
        "-y",
        "samarth-gtm-mcp"
