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

interactive flow, which is useful for acting as an app user or for read-only
access with a restricted API key.
