Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

  1. Open your agent's MCP configuration file.
  2. Merge the snippet below into it.
  3. Restart the agent — the "Klaviyo MCP Server" tools will be available.

Description

The Klaviyo MCP server is the official bridge between Klaviyo's marketing platform and AI clients. Instead of exporting reports by hand, an agent can query your own Klaviyo data directly: how a campaign performed, where a flow is losing people, and what to change next, and it can help draft new campaigns.

How it connects. Klaviyo runs the server as a hosted remote endpoint at https://mcp.klaviyo.com/mcp, so nothing has to be installed or kept running locally. You sign in with OAuth, which scopes the agent to the Klaviyo account you authorise. Klaviyo's developer portal also documents a local-server option, and its connection guide covers Claude, Cursor and ChatGPT.

Who it is for. Lifecycle and email/SMS marketers, ecommerce operators and agencies who already live in Klaviyo and want an assistant that works from real performance data rather than pasted screenshots. Because it acts on a live account, review any write action before approving it.

Tool lists are maintained by Klaviyo and grouped by category on its "Available tools" documentation page, so check there for the current set.
