Manage your Kit (ConvertKit) subscribers directly

Stop jumping between your browser tabs to find user data. Use `get_subscriber_details` or `search_subscriber_by_id` to pull info right into your Claude Desktop conversation. Updating records happens instantly. You can run `update_subscriber` to change metadata or custom fields based on the context of your current chat.

Organize your audience with precision

Tagging is the backbone of your email strategy. Use `list_all_tags` to see your current structure and `apply_tag_to_subscriber` to segment users during your workflow. You avoid manual errors by letting your agent handle the heavy lifting. It keeps your lists clean and ready for the next campaign.

Track growth from your chat interface

Get a bird's-eye view of your account with `get_account_growth_summary`. It gives you the numbers you need to decide what to do next without a dashboard login. If you need to verify your reach, use `list_subscribers` or `list_optin_forms` to check your current acquisition channels. All data flows through your MCP Server.
