# Your Kit list. In your agent.

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

Connect Kit, the creator email platform formerly called ConvertKit, to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads subscribers, tags, sequences and broadcast stats, and drafts a broadcast you review. Creating or scheduling a broadcast, tagging a subscriber, or adding one to a sequence is a separate call that approvals can hold.

## 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 Kit after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Last week's numbers. Next week's draft

Let your agent read how your last broadcast did, then draft the next one for the right tag. You schedule it.

You ask your agent: "Look at the stats for my last Kit broadcast. Then draft next week's broadcast for subscribers tagged workshop. Save it as a draft and do not schedule it."

It calls CoreSpeed:

- `kit__list_broadcasts`: ok, 356 ms
- `kit__get_broadcast_stats`: ok, 289 ms
- `kit__create_broadcast`: ok, 571 ms

It reads from: Kit.

## Questions

### Is this the Kit that used to be ConvertKit?

Yes. Kit is the creator email platform formerly called ConvertKit. CoreSpeed connects to your Kit account.

### Can my agent send a Kit broadcast?

It saves a draft, or schedules a broadcast by giving it a send time. Both are tool calls that approvals can hold for a person. How approvals work: https://corespeed.io/docs/approvals

### Can it unsubscribe someone?

Yes, as a separate call. Kit keeps the subscriber's record, history and tags after an unsubscribe.

### 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
