How do I authenticate?

Set your Klaviyo private API key as the environment variable `KLAVIYO_API_KEY` in a `.env` file before starting the server.

How can I test the server?

Run `npm run inspect` to launch the MCP Inspector, which provides a web interface to browse tools and resources and test them with different inputs.

What credentials does it need?

It reads `KLAVIYO_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
