• Full GA4 reporting access — dimensions, metrics, segments
• Real-time and historical data queries
• Automatic token refresh and credential management
• Works with Claude Code, Claude Desktop, Cursor, Windsurf, and any MCP client

Why Use a Managed MCP Server?

Connecting to GA4 programmatically typically requires:

1. Creating a Google Cloud Platform project
2. Enabling the Analytics Data API
3. Setting up OAuth credentials or a service account
4. Downloading key files and configuring authentication
5. Hosting a server to run the MCP endpoint
6. Managing token refresh and API quotas

Cogny handles all of this. Sign in with Google, select your GA4 properties, and get a working MCP endpoint immediately.

What Can Claude Do With GA4 Data?

With the GA4 MCP server, Claude can:

Setup in 3 Steps

Step 1: Create a Cogny Account

Go to cogny.com, sign up, and create a warehouse.

Step 2: Connect Google Analytics 4

In your dashboard, find Google Analytics 4 under the channels list and click connect.

Sign in with your Google account that has GA4 access. Select which properties to connect.

Step 3: Add to Claude Code

In your Cogny dashboard, generate an API key. Then add the Cogny MCP server to your Claude Code config. This is the same endpoint for all Cogny integrations — the tools available are determined by which accounts you've connected.

{
  "mcpServers": {
    "cogny": {
      "type": "http",
      "url": "https://app.cogny.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Done. Claude now has read access to your GA4 data — and any other platforms you connect through Cogny.

Common Questions
