Google Analytics MCP Server

mcp-name: io.github.surendranb/google-analytics-mcp

Connect Google Analytics 4 data to AI agents, agentic workflows, and MCP clients. Give agents analysis-ready access to website traffic, user behavior, and performance data with schema discovery, server-side aggregation, and safe defaults that reduce data wrangling.

Built for: AI agents, analyst copilots, and MCP runtimes across Claude, ChatGPT, Cursor, Windsurf, and custom hosts.

I also built a Google Search Console MCP that enables you to mix & match the data from both the sources

Why Agents Use This Server

• Analysis-ready outputs with server-side aggregation, so agents spend more time answering questions and less time wrangling rows
• Live schema discovery for each GA4 property, including category-based exploration for dimensions and metrics
• Context-safe defaults that estimate large datasets before they blow up a conversation or workflow
• Portable MCP surface that works across agent runtimes, IDE copilots, and custom automation

---

Step 1: Setup Google Analytics Credentials

Create Service Account in Google Cloud Console

1. Go to Google Cloud Console
2. Create or select a project:
   • New project: Click "New Project" → Enter project name → Create
   • Existing project: Select from dropdown
3. Enable the Analytics APIs:
   • Go to "APIs & Services" → "Library"
   • Search for "Google Analytics Data API" → Click "Enable"
4. Create Service Account:
   • Go to "APIs & Services" → "Credentials"
   • Click "Create Credentials" → "Service Account"
   • Enter name (e.g., "ga4-mcp-server")
   • Click "Create and Continue"
   • Skip role assignment → Click "Done"
5. Download JSON Key:
   • Click your service account
   • Go to "Keys" tab → "Add Key" → "Create New Key"
   • Select "JSON" → Click "Create"
   • Save the JSON file - you'll need its path

Add Service Account to GA4

1. Get service account email:
   • Open the JSON file
   • Find the client_email field
   • Copy the email (format: ga4-mcp-server@your-project.iam.gserviceaccount.com)
2. Add to GA4 property:
   • Go to Google Analytics
   • Select your GA4 property
   • Click "Admin" (gear icon at bottom left)
   • Under "Property" → Click "Property access management"
   • Click "+" → "Add users"
   • Paste the service account email
   • Select "Viewer" role
   • Uncheck "Notify new users by email"
   • Click "Add"

Find Your GA4 Property ID

1. In Google Analytics, select your property
2. Click "Admin" (gear icon)
3. Under "Property" → Click "Property details"
4. Copy the Property ID (numeric, e.g., 123456789)
   • Note: This is different from the "Measurement ID" (starts with G-)

Test Your Setup (Optional)

Verify your credentials:

pip install google-analytics-data

Create a test script (test_ga4.py):

import os
from google.analytics.data_v1beta import BetaAnalyticsDataClient

# Set credentials path
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "/path/to/your/service-account-key.json"

# Test connection
client = BetaAnalyticsDataClient()
print("✅ GA4 credentials working!")

Run the test:

python test_ga4.py

If you see "✅ GA4 credentials working!" you're ready to proceed.

Step 2: Install the MCP Server

There are two supported ways to launch the server:

• ga4-mcp-server when the installed console script is available on your PATH
• python -m ga4_mcp when you want to use a specific interpreter or virtual environment

Method A: Install from PyPI (Recommended)

python3 -m pip install google-analytics-mcp

If your machine uses python instead of python3, run:

python -m pip install google-analytics-mcp

Option 1: Use the console script

Use this when ga4-mcp-server is available on your PATH:

{
  "mcpServers": {
    "ga4-analytics": {
      "command": "ga4-mcp-server",
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/your/service-account-key.json",
        "GA4_PROPERTY_ID": "123456789"
      }
    }
  }
}

Option 2: Use an explicit Python interpreter

Use this when you want to pin the exact Python runtime or when the console script is not on your PATH.

If python3 --version worked:

{
  "mcpServers": {
    "ga4-analytics": {
      "command": "python3",
      "args": ["-m", "ga4_mcp"],
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/your/service-account-key.json",
        "GA4_PROPERTY_ID": "123456789"
      }
    }
  }
}

If python --version worked:

{
  "mcpServers": {
    "ga4-analytics": {
      "command": "python",
      "args": ["-m", "ga4_mcp"],
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/your/service-account-key.json",
        "GA4_PROPERTY_ID": "123456789"
      }
    }
  }
}

Method B: Install from a local clone

git clone https://github.com/surendranb/google-analytics-mcp.git
cd google-analytics-mcp
python3 -m venv .venv
source .venv/bin/activate
python -m pip install .

If you plan to modify the package locally, use python -m pip install -e . instead.

MCP Configuration:

{
  "mcpServers": {
    "ga4-analytics": {
      "command": "/full/path/to/google-analytics-mcp/.venv/bin/python",
      "args": ["-m", "ga4_mcp"],
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/your/service-account-key.json",
        "GA4_PROPERTY_ID": "123456789"
      }
    }
  }
}

---

Step 3: Update Configuration

Replace these placeholders in your MCP configuration:

• /path/to/your/service-account-key.json with the absolute path to your JSON key
• 123456789 with your numeric GA4 Property ID
• /full/path/to/google-analytics-mcp/.venv/bin/python with your virtual environment's Python path (Method B only)

---

🚀 Performance Optimizations

This MCP server includes built-in optimizations to prevent context window crashes and ensure smooth operation:

Smart Data Volume Management

• Automatic row estimation - Checks data volume before fetching
• Interactive warnings - Alerts when queries would return >2,500 rows
• Optimization suggestions - Provides specific recommendations to reduce data volume

Server-Side Processing

• Intelligent aggregation - Automatically aggregates data when beneficial (e.g., totals across time periods)
• Smart sorting - Returns most relevant data first (recent dates, highest values)
• Efficient filtering - Leverages GA4's server-side filtering capabilities

User Control Parameters

• limit - Set maximum number of rows to return
• proceed_with_large_dataset=True - Override warnings for large datasets
• enable_aggregation=False - Disable automatic aggregation
• estimate_only=True - Get row count estimates without fetching data

Example: Handling Large Datasets

# This query would normally return 2,605 rows and crash context window
get_ga4_data(
    dimensions=["date", "pagePath", "country"],
    date_range_start="90daysAgo"
)
# Returns: {"warning": True, "estimated_rows": 2605, "suggestions": [...]}

# Use monthly aggregation instead
get_ga4_data(
    dimensions=["month", "pagePath", "country"], 
    date_range_start="90daysAgo"
)
# Returns: Clean monthly data with manageable row count

Troubleshooting

If ga4-mcp-server is not found:

• Use the explicit interpreter launch style instead: python -m ga4_mcp
• Reinstall with the same Python interpreter your MCP client will use

If you get No module named ga4_mcp:

/full/path/to/python -m pip install google-analytics-mcp

Install the package with the exact interpreter you reference in your MCP configuration.

Permission errors:

# Try user install instead of system-wide
python -m pip install --user google-analytics-mcp

If the server says the credentials file is missing:

1. Verify the JSON file path is absolute, correct, and accessible
2. Check service account permissions:
   • Go to Google Cloud Console → IAM & Admin → IAM
   • Find your service account → Check permissions
3. Verify GA4 access:
   • GA4 → Admin → Property access management
   • Check for your service account email

If the server says GA4_PROPERTY_ID is invalid or queries return no data:

• Use the numeric Property ID (for example 123456789)
• Do not use the Measurement ID (for example G-XXXXXXXXXX)
• Confirm the service account has at least Viewer access on that property

API quota/rate limit errors:

• GA4 has daily quotas and rate limits
• Try reducing the date range in your queries
• Wait a few minutes between large requests
