Build dynamic customer segments in Windsurf

Windsurf lets Cascade map out your Klaviyo audience targeting. Cascade pulls your active Klaviyo user segments with `list_segments` and grabs your custom metrics using `list_metrics` in one go. Once Windsurf has the Klaviyo data, it sets up your targeting rules. You can ask Windsurf to find high-value Klaviyo users who haven't purchased lately, and this MCP Server handles the actual calls.

Auto-trigger behavior events on your site

This MCP Server allows Cascade to write Klaviyo tracking scripts and tests them right inside your Windsurf workspace. It uses `track_event` to send custom user actions straight to your Klaviyo account, allowing Windsurf to verify the integration in real time. If a user signs up, Windsurf triggers `create_profile` to register them in Klaviyo immediately. You skip manual Klaviyo API testing because Windsurf verifies the payload structure before deploying.

Audit automated marketing campaigns

Keep an eye on your Klaviyo messaging performance inside Windsurf. This MCP Server lets Windsurf scan your active setups using `list_automated_flows` and pull your Klaviyo template list with `list_email_templates`. Cascade checks for broken links or outdated copy across your Klaviyo emails in Windsurf. It lists your active subscriber lists with `list_marketing_lists` so Windsurf can verify that your automated Klaviyo messages reach the right people.
