Web Analytics & Tracking MCP Server

A production-ready Model Context Protocol (MCP) server for Google Tag Manager (GTM), Google Analytics 4 (GA4) Measurement Protocol, DataLayer schema validation, Meta CAPI auditing, and tracking code snippet generation.

📌 Features

• 🎯 DataLayer Schema Validator: Automatically validates GTM dataLayer.push objects against GA4 e-commerce schemas (purchase, add_to_cart, lead, etc.).

• 🚀 GA4 Measurement Protocol Event Transmitter: Transmits server-side events directly to Google Analytics 4 via Measurement Protocol API.

• 🛠️ Tracking Code Snippet Generator: Generates production-ready code snippets for GTM window.dataLayer.push, GA4 gtag.js, and React tracking hooks.

• 📊 Tracking Quality & EMQ Auditor: Audits tracking event payloads for GA4 and Meta Conversions API (CAPI), scoring readiness from 0-100 and providing recommendations.

• 📑 Built-in Specification Resource: Exposes static GA4 e-commerce standard schemas as an MCP resource (ga4://spec/ecommerce).
