What is the MCP Kit MCP server?

Connect MCP Kit to Claude, Cursor or any other MCP client and it stops being a tab you switch to. [DEPRECATED — use Kit's official MCP at https://app.kit.com/mcp] MCP server for Kit.com (formerly ConvertKit) email marketing API - manage subscribers, tags, sequences, broadcasts, forms, and more. The mcp kit mcp server is what makes that connection.

What the server does

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.

  • Manage subscribers — - List, create, update, and organize your email subscribers
  • Handle tags efficiently — - Create tags, add/remove tags from subscribers, list subscribers by tag
  • Work with sequences — - View email sequences and add subscribers to automated sequences
  • Create broadcasts — - Draft and manage email campaigns
  • Analyze your list — - Query subscriber data with filters (status, date ranges, custom fields)
  • Automate workflows — - Let Claude handle repetitive email marketing tasks

Installation

The server ships on npm as kit-mcp-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Broadcasts — The Broadcasts tool exposed by this server
  • Forms — The Forms tool exposed by this server

Credentials and setup notes

Configuration is passed through the environment: KIT_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Node.js 18+ - A Kit.com account - Your Kit.com API key (v4 API)

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Kit's toolset — Broadcasts, Forms — is a fair guide to whether it matches your workflow. It is maintained by aplaceforallmystuff; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
