# Your Klaviyo. In your agent.

Source: https://corespeed.io/integrations/klaviyo

Connect Klaviyo to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your lists, segments, profiles, campaigns and flows, so it can tell you which flows are live and which campaigns are scheduled. It uses your own Klaviyo account. Creating a list or a profile, or adding profiles to a list, is a separate call.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Klaviyo after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Know what is live. Before you change it

Let your agent list your flows and campaigns, read their status, and point out what is still a draft or switched to manual.

You ask your agent: "List our Klaviyo flows and this month's email campaigns. Tell me which flows are live, which are drafts, and which campaigns are scheduled. Do not change anything."

It calls CoreSpeed:

- `klaviyo__list_flows`: ok, 341 ms
- `klaviyo__list_campaigns`: ok, 466 ms

It reads from: Klaviyo.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.
2. **Connect Klaviyo**: Authorize the account and the content you need.
3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

## Questions

### Can my agent send a Klaviyo campaign?

No. The Klaviyo tools list campaigns and flows and read their status. Sending and scheduling stay in Klaviyo.

### Can it change my lists and profiles?

Yes. Creating a list or profile, updating a profile, or adding profiles to a list is a separate call, which approvals can hold. How approvals work: https://corespeed.io/docs/approvals

### Does adding a profile to a list subscribe them?

No. It adds list membership only. Email or SMS marketing consent is a separate step in Klaviyo.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
