Klaviyo

Klaviyo is the email and SMS marketing platform ecommerce businesses use to run campaigns, automated flows, and customer segments. The official Klaviyo MCP server lets your agent check performance and build campaigns directly — no API key pasted into TerminalSync, just your own Klaviyo account login.

Ask "Show me the performance of my email campaigns from the last 30 days" and the agent pulls the numbers from your account. Ask "Create an email campaign promoting our Memorial Day sale" and it drafts it against your real lists and templates. It's built for reviewing campaign and flow performance, managing profiles and segments, and drafting new campaigns.

What you can ask

• "Show me the performance of my email campaigns from the last 30 days."
• "Which flows are performing the best in terms of conversions?"
• "Create an email campaign promoting our Memorial Day sale."
• "Find this customer's profile and add them to the VIP segment."

How you connect

This connector doesn't ask you to paste an API key. It uses your own Klaviyo account login:

1. Enable the connector in TerminalSync.
2. The mcp-remote bridge opens Klaviyo's login in your browser and asks you to authorize access (OAuth with dynamic client registration).
3. Approve it with your account — the connector only sees and does what your role allows. Klaviyo's own docs are at developers.klaviyo.com.

Honest note: this is a server hosted by Klaviyo (https://mcp.klaviyo.com/mcp), not something that runs on your computer. Klaviyo's docs state this server is only available to users with an Owner, Admin, or Manager role on the account, and it can create and send real campaigns — review before sending.
