MCP server

Use Growth Method from your AI client, like ChatGPT or Claude, via our MCP server.

The Growth Method MCP server is built on our API and lets you use your preferred AI client to work with Growth Method. It’s popular with AI-first marketers who already spend time in tools like ChatGPT and Claude. Here, Growth Method acts as a headless backend, providing data and functions to your AI agent, so you get campaign and experiment management without context switching into our app.

Who it’s for

Teams that use our MCP server tend to:

  • Spend a lot of time in AI tools like ChatGPT and Claude
  • Have a relatively modern marketing stack and are comfortable connecting data sources via MCP

Example workflow

With the Growth Method MCP server and a GA4 or PostHog MCP server connected to ChatGPT:

  1. “Get details of the pricing page campaign from Growth Method.”
  2. “Use PostHog to compare traffic and conversion for the /pricing page before and after this campaign went live.”
  3. “Add this traffic and conversion data to Growth Method for campaign analysis.”

Connecting

To connect your AI client, create an API token in Growth Method and add it to your client:

  1. In Growth Method, go to User settings and select the API Tokens tab.
  2. Enter a name, then select Create Token.
  3. Copy the token. For your security it’s shown only once, and it expires one year after you create it.
  4. In your AI client, such as Claude or ChatGPT, add a new MCP server at https://app.growthmethod.com/mcp.
  5. Set the client to send your token in an Authorization: Bearer header.

The server uses the Streamable HTTP transport, and your token acts on your behalf as a signed-in user. When it expires after a year, create a new token and update your client.
