Google Analytics recently released an MCP Server you can use to connect Gemini, Chat GPT, Claude or other LLMs directly to your GA properties. I configured it for use in a Claude project, and frankly I was blown away by the results. I’ve tested a variety of AI-driven analysis tools and features, and this is the best of what I’ve tried. I used it to generate meaningful insights for my clients, and was able to converse with it about data as if I had an eager, competent, and speedy analyst by my side. I’ve tested it on several properties, and have gained a new understanding of my clients’ overall website performance and have generated specific, actionable recommendations. You can see a few of those insights in the “How Well Does It Work” section below.
I chose Claude because I like Anthropic’s default privacy settings and I’ve had good results from other Claude Projects I’ve created, but I think you would achieve comparable results with ChatGPT or Gemini.
The Github repository has instructions, but they are pretty high-level. I found I still had to figure a few things out.
For context:
These are the steps I took. For the most part, the steps below are inclusive of the instructions with the Github repository, but it wouldn’t hurt to review both instructions.
I started by opening the bash shell in Console. It had been a while since I’d worked in python locally, so first I checked to see what version I have.
python --versionI have Python 3.9.7 – good enough. I didn’t have Homebrew installed so I added that.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"And I followed post-install instructions to add Homebrew to the shell:
echo 'eval "$(/usr/local/bin/brew shellenv)"' >> ~/.bash_profile
eval "$(/usr/local/bin/brew shellenv)"Then I installed pipx and added the path to local environment variables:
brew install pipx
pipx ensurepathThen I installed the Google Analytics MCP server:
pipx install git+https://github.com/googleanalytics/google-analytics-mcp.gitIt had also been a while since I’d used the Google Cloud CLI, so I checked that before setting the Application Default Credentials (ADC):
gcloud versionIt was pretty old, so I decided to update:
gcloud components updateThen I created a new Google Auth Platform Client (make sure you are in the GCP project you want to use) and downloaded the client ID JSON file. I needed that to set Application Default Credentials. Then run this to set your credentials. You’ll need to replace the client-id-file location with the location of your client ID JSON file.
gcloud auth application-default login \
--scopes https://www.googleapis.com/auth/analytics.readonly,https://www.googleapis.com/auth/cloud-platform \
--client-id-file="/Users/[username]/Library/Application Support/Claude/client_secret_...json"Make sure to authenticate with credentials that have access to your Google Analytics properties.
I’m using Claude Desktop versus the web version, since the MCP server is running on my local machine. To make the MCP server available to Claude, all you have to do is to add an entry for it in the claude_desktop_config.json file, which is located here on a Mac:
~/Library/Application Support/Claude/claude_desktop_config.jsonYou may need to create the file if it doesn’t exist. You can also find it in the Claude Desktop app by going to your user profile, then Settings > Developer > Edit Config. Add something like this to the file – make sure to replace the path to the MCP binary with the correct path for your machine:
{
"mcpServers": {
"google-analytics-mcp": {
"command": "/Users/[username]/.local/pipx/venvs/google-analytics-mcp/bin/google-analytics-mcp",
"args": []
}
}
}I thought I would need to do more to hook it up, but that’s it – since I already configured authentication, the MCP server is now available for use whenever I use Claude.
Next, create your Claude Project. If you aren’t familiar with Claude projects, start here. So far, all I’ve done is to add instructions (copy them below). You’ll probably want to come up with your own, but maybe this will help you get started – it’s formatted in markdown, which Claude understands.
I also plan on adding knowledge to the project. I have a lot of best practices I follow when interpreting and reporting on GA data, and I want my project to follow those. But for now, the instructions are good enough.
# Google Analytics Insights Project Instructions
## Project Overview
You are a Google Analytics expert consultant specializing in generating actionable business insights from GA4 data using the Google Analytics MCP server. Your role is to help clients understand their website performance, user behavior, and growth opportunities through data-driven analysis.
## Getting Started Protocol
**ALWAYS begin each new analysis by:**
1. **Request Property Information**: Ask the user for their Google Analytics property name
2. **Clarify Property ID**: If the property name is ambiguous or multiple properties might exist with similar names, ask for the specific Property ID (format: 123456789)
3. **Confirm Access**: Verify you can access the specified property through the MCP server
4. **Set Analysis Scope**: Determine the date range and specific business questions to address
## Primary Objectives
- Analyze Google Analytics data to identify trends, patterns, and opportunities

This is great! Thank you for the steps, exactly what I was looking for since I already have Claude connected to Ahrefs.
Very cool - I imagine you are getting some very powerful insights by connecting to both.
