We make QuerySail, one of the servers on this list. We checked every other server against its own README or website on October 28, 2026. Where a project does not state a fact, we say so. If something here is wrong or out of date, email support@querysail.com and we will fix it.

The servers
Google Analytics MCP server (Google)
Google's own server, with 3,577 stars on GitHub. It has standard, realtime and funnel reports, account and property details, custom dimensions and metrics, Google Ads links and property annotations. Its repository calls it experimental.
- Good fit if you already work in Google Cloud or need funnel reports.
- Check first: Google documents no hosted version. ChatGPT and claude.ai only connect to servers on the internet, so for them you host it and secure it yourself.
QuerySail
Our product. Five tools: standard reports with any GA4 dimension, metric and filter; period comparisons with the top gaining and losing channels, sources or pages; realtime reports; and field lists with your custom definitions and key events. Answers say when Google thresholded or sampled a report.
- Good fit if you want GA4 in ChatGPT or claude.ai without running anything, or you also want Search Console on the same plan.
- Check first: it has no funnel reports, and there is no free plan after the trial.
Windsor.ai
A marketing data platform with more than 350 sources, Search Console among them, behind one connector.
- Good fit if you want GA4 next to many other marketing data sources in one place.
- Check first: the free plan covers one data source, so GA4 and Search Console together need a paid plan.
google-analytics-mcp (surendranb)
Eight tools, 243 stars on GitHub. Besides reports and realtime data, it looks up which dimensions and metrics work together, and it has built-in analysis playbooks that it loads from GitHub.
- Good fit if you use a coding assistant on your computer and want guided analyses.
- Check first: it sends anonymous usage data unless you set DO_NOT_TRACK=1. ChatGPT and claude.ai only connect to servers on the internet.
How to choose
- Which AI app do you use? ChatGPT and claude.ai need a server on the internet, so pick a hosted server or host one yourself. Claude Desktop, Claude Code and Cursor can run any of them.
- Do you want to set up Google Cloud? Google's server needs a Google Cloud project, two APIs turned on and Application Default Credentials. The other open-source server needs a service account key. The hosted servers need only a sign-in.
- Do you need funnel reports? Google's server has them. QuerySail does not.
- Do you also want Search Console? QuerySail includes it on the same plan, and Windsor.ai offers it as another data source. See the best Google Search Console MCP servers.
- What is your budget? The open-source servers are free to run. Windsor.ai has a free plan for one data source. QuerySail costs $8 per month.
