Klaviyo · Marketing & SEO

Last updated September 16, 2026

Read Klaviyo profiles, lists, segments, flows and campaign metrics so an agent can report on and act in email and SMS marketing.

This is a first-party server: it is published by Klaviyo, so it tracks their own API rather than a community wrapper around it. It is a hosted endpoint you connect over streamable HTTP at https://mcp.klaviyo.com/mcp, which we probed on 2026-09-16 and found live.

Connect it once to a BusinessMCP workspace and every AI you use — Claude, GPT, Gemini, and your coding agents — reaches it through one endpoint, alongside everything else you have connected. That is the difference between a directory entry and a working integration: you authorise once, not once per model.

Let a teammate ask for Klaviyo work in plain language rather than clicking through the UI.
Combine Klaviyo with the rest of your stack in one agent thread, without switching tools.

Frequently asked questions

Is there an official Klaviyo MCP server?

Yes. Klaviyo publishes it as a hosted endpoint at https://mcp.klaviyo.com/mcp. We probed it on 2026-09-16 and it responded.

Do I need an API key?

It authenticates with OAuth rather than a pasted key — you authorise it once from your Klaviyo account. That is the pattern most 2026 vendor servers use, and it is safer than putting a long-lived key in a config file.

Can I use it with something other than Claude?

Yes. MCP is an open protocol, so any client that speaks it can call this server. Connecting it through BusinessMCP exposes it to every model you have connected at once.
