# MCP Client

> An Introduction to our data assistant

Using Growth Method customers can use our MCP client to add results to marketing campaigns without having to manually copy & paste data from analytics providers such as GA4 and PostHog.

For marketers that wish to use natural language to retrieve campaign results quickly and easily, this reduces friction and the need to switch between different marketing tools when analysing campaign results.

## Popular tools

Below are some of the popular analytics tools used by Growth Method customers. For further information see [https://growthmethod.com/mcp-servers/](https://growthmethod.com/mcp-servers/).
