Full read-write Claude connector for ConvertKit
Let Claude tag subscribers and draft broadcasts in ConvertKit
Stop clicking through the ConvertKit dashboard to tidy your list and prep campaigns. Claude tags subscribers, adds them to sequences, and drafts broadcasts where your audience already lives, queuing a send only once you approve.
ConvertKit (now Kit) is an email marketing platform built for creators, with subscribers, tags, sequences, and broadcasts. Teams want Claude to do more than read campaign stats: to tag subscribers, manage sequences, and queue broadcasts inside the account.
What is a ConvertKit MCP server?
A ConvertKit MCP server is a small hosted service that exposes ConvertKit's data and actions to Claude over the Model Context Protocol, so Claude can campaigns, lists, and audiences inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can ConvertKit's current connector do today?
ConvertKit (now Kit) does ship an official MCP connector, and it covers a fixed, standard slice of the platform. A custom connector goes past that generic tool set to fit your exact workflow: the specific tagging, sequence, and broadcast actions you run, custom fields, tight permission scoping, and human-in-the-loop confirmation on the steps that matter.
What does full read-write ConvertKit access unlock?
Full read-write ConvertKit access lets Claude tag and untag subscribers, add them to sequences, draft and update broadcasts, manage custom fields, and queue a send once you approve it. The list hygiene and campaign prep that used to mean clicking through the dashboard happen where your subscribers already live.
- Add or remove tags on subscribers based on a query you describe
- Add people to a sequence based on a query you describe
- Draft a broadcast with subject and body for your review
- Update custom fields on a subscriber record
- Create a new tag and apply it to a segment
- Add subscribers to an existing form
- Queue an approved broadcast to send
Can Claude tag subscribers in ConvertKit?
Yes. Claude can tag subscribers in ConvertKit, adding or removing tags on the segment you describe instead of just reading the list back. It can also create a new tag and apply it. The official connector ships a fixed tool set, so these actions come from a purpose-built connector shaped to the way your team actually works.
Can Claude manage sequences in ConvertKit?
Claude can manage sequences in ConvertKit by subscribing people to a sequence based on a query you give it, and by updating custom fields on subscriber records. It works the audience you point it at, with destructive moves like removing a tag gated behind a confirmation step you control.
Can Claude send a broadcast in ConvertKit?
Claude can draft a broadcast in ConvertKit with the subject and body for your review, but sending or queuing it is a separate, gated action. It stages everything and waits for your approval before anything reaches your list, so nothing goes out by surprise. The connector never exceeds your own account's access.
How a ConvertKit connector works
We build a small MCP server that authenticates to ConvertKit with OAuth or a scoped API key, requesting only the access the work needs. Read tools (list subscribers, read broadcasts) and write tools (tag, sequence, broadcast) are separated, and outbound or destructive actions like sending a broadcast or unsubscribing require your confirmation. Claude never has more access than the connected ConvertKit account already has, and the server can sit behind IP allowlisting if you need it.
