MCP server for Kit.com (ConvertKit) - manage subscribers, tags, sequences, broadcasts
Overview
Deprecated community MCP server that lets an assistant manage Kit.com (ConvertKit) subscribers, tags, sequences, broadcasts, forms and webhooks.
- What you can do
- Read account details and list subscribers with status, date and pagination filters
- Create and update subscribers, and add or remove their tags
- List, create, rename and delete tags, and list subscribers by tag
- List sequences and add subscribers to them
- List, create, update and delete broadcasts, and list or add subscribers to forms
- List custom fields, and list, create or delete webhooks
- When to use it
- Only if you already depend on this community server or need a quick local bridge to a Kit.com account for newsletter and email-marketing chores. The README states the project is deprecated and unmaintained and recommends migrating to Kit's official MCP servers, so new users should start there.
- Requirements
- Runs locally over stdio as an npm package (kit-mcp-server) and needs Node.js 18 or newer. Requires a Kit.com account and a Kit API v4 key supplied in the KIT_API_KEY environment variable.
Installation
In SourceWeft
- Open Mcp Kit in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

MCP Kit Server
[npm version] [CI] [License: MIT] [MCP] [Status: Deprecated]
An MCP (Model Context Protocol) server that connects AI assistants like Claude to the Kit.com (formerly ConvertKit) email marketing platform. Manage your email lists, subscribers, broadcasts, sequences, and more through natural language.
[!WARNING] This project is deprecated and no longer maintained. Kit now ships official, first-party MCP servers that supersede it with broader API coverage and managed authentication. Please migrate — see below.
⚠️ Deprecated — use Kit's official MCP servers
This community server was built before Kit offered its own MCP. Kit now maintains official servers that cover far more of the Kit API v4 surface (including analytics, commerce, segments, and bulk operations), handle auth for you, and stay current with API changes. New and existing users should migrate.
