Overview

Connect to Klaviyo through Klaviyo hosted MCP OAuth. The Klaviyo integration exposes hosted MCP access through Klaviyo’s official remote MCP server.

​
Connect In Mistle

Open Integrations in the dashboard, choose Klaviyo, then select Klaviyo MCP OAuth. The browser redirects to Klaviyo, the user approves access, and the returned OAuth credentials are stored for the connection. There are no user-entered secret fields for this target.

​
Use With A Sandbox Profile

After the connection exists:
  1. Open the sandbox profile that should use Klaviyo.
  2. Add Klaviyo to the profile’s integration configuration.
  3. Select the Klaviyo MCP tool.
  4. Save and publish the profile version.
