Klaviyo

Cursor plugin that connects agents to Klaviyo through Klaviyo's official remote Model Context Protocol server.

Build segments, draft campaigns and flows, look up profiles and events, and pull reporting from the signed-in Klaviyo account.

Install

1. Open Cursor Settings → Plugins.
2. Search for Klaviyo.
3. Click Install, then complete the Klaviyo sign-in prompt.

Or run /add-plugin klaviyo in chat.

Auth is OAuth with Dynamic Client Registration. Cursor registers itself and prompts for Klaviyo sign-in when the plugin connects — there is no API key or client ID to configure.

Before you connect

You need the Owner, Admin, or Manager role on the Klaviyo account. Tool calls run with that user's permissions.

What agents can do

Category	Capabilities
Profiles & events	Look up and update profiles, push events, and manage consent and data-privacy requests
Lists & segments	Create and query lists and segments, and manage membership
Campaigns & flows	Draft, schedule, and inspect email, SMS, and push campaigns and flows
Templates & catalogs	Manage templates, images, coupons, catalogs, and reviews
Reporting	Campaign, flow, form, and segment performance reporting
Account config	Accounts, brands, tags, sending domains, webhooks, and applications

The hosted runtime is the source of truth for tool names and schemas.

Notes

• Tool calls run as the Klaviyo user who authorizes the connection and cannot exceed that user's permissions.
• The full catalog is large. Klaviyo supports URL query parameters to trim it — ?core-tools-only=true for the core set, ?read-only=true to drop every write tool, and ?toolsets=profiles:read,campaigns:read to pick specific toolsets. Edit the plugin's server URL if you want a narrower surface.
• ?disable-tools-with-user-generated-content=true hides tools that return user-generated content, which is worth setting on shared or sensitive accounts.
• Add ?company=your-company-slug to pin a specific account when you belong to more than one.
• The URL must have no trailing slash.
