Kit MCP Server

@dancumberland/kit-mcp

The most complete MCP server for Kit.com (formerly ConvertKit). 13 agent-optimized tools covering 100% of the Kit V4 API — including engagement analytics, bulk operations, and broadcast click tracking that no other Kit MCP offers.

How This Is Different

Other Kit MCP servers wrap each API endpoint as a separate tool (29+ tools). That approach breaks in practice:

Engagement Analytics (Exclusive)

This is the only Kit MCP that can answer "who are my most engaged subscribers?":

> Find my most engaged 100 subscribers who've been on my list over 6 months

Subscriber Comparison (100 of 100 loaded, sorted by open rate):

  1. Alice <alice@example.com> — Open: 82.3% | Click: 24.1% | Sent: 95 | Last open: 2026-03-15 (ID: 456)
  2. Bob <bob@example.com> — Open: 71.0% | Click: 18.5% | Sent: 102 | Last open: 2026-03-14 (ID: 789)
  ...

Other Kit MCPs can list subscribers and get basic profiles, but can't fetch engagement stats, compare across subscribers, or filter by engagement metrics.

What This Does

Connects any MCP client (Claude Desktop, Claude Code, Cursor, Windsurf, etc.) to your Kit.com email marketing account. Ask questions naturally:

• "How many subscribers do I have and how's my list growing?"
• "Show me my broadcast stats from last week"
• "Find my most engaged subscribers from the past 6 months"
• "Tag everyone who signed up through my landing page"
• "Create a draft broadcast for my newsletter"
• "Which links got the most clicks in my last broadcast?"

No coding required — just set it up and start talking.

Prerequisites

1. Node.js 22+ — Download from nodejs.org. Check with node --version.
2. A Kit.com account — Free or paid, any plan.
3. Your Kit API key — kit.com → Account Settings → Developer. Starts with kit_.

Setup: Claude Desktop App (Recommended)

Step 1: Find your config file

Mac:

open ~/Library/Application\ Support/Claude/

Open claude_desktop_config.json in any text editor.

Windows:

%APPDATA%\Claude\claude_desktop_config.json

Step 2: Add the Kit MCP server

If the file is empty or doesn't exist, paste this (replace your-kit-api-key with your actual key):

{
  "mcpServers": {
    "kit": {
      "command": "npx",
      "args": ["-y", "@dancumberland/kit-mcp@latest"],
      "env": {
        "KIT_API_KEY": "your-kit-api-key"
      }
    }
  }
}

If you already have other MCP servers, add "kit" inside the existing "mcpServers" block with a comma after the previous entry.

Step 3: Restart Claude Desktop

Fully quit (not just close the window) and reopen.

Step 4: Verify it works

Test my Kit connection

Claude should respond with your account name, auth method, and rate limit.

Setup: Claude Desktop with Cowork

Cowork is Claude Desktop's background agent. After completing the setup above, Cowork automatically has access to your Kit tools.

Example tasks:

• "Every morning at 8am, summarize my subscriber growth and email performance from the last 24 hours."
• "Every Monday at 9am, compare my broadcast stats from the past week — open rates, click rates, and unsubscribes."
• "Every Friday, list all tags with fewer than 10 subscribers (candidates for cleanup)."

Setup: Claude Code (CLI)

Add to .claude/settings.local.json or ~/.claude/settings.json:

{
  "mcpServers": {
    "kit": {
      "command": "npx",
      "args": ["-y", "@dancumberland/kit-mcp@latest"],
      "env": {
        "KIT_API_KEY": "your-kit-api-key"
      }
    }
  }
}

Setup: Cursor

1. Open Settings (Cmd+,)
2. Search for "MCP"
3. Click "Add MCP Server"
4. Add:

{
  "kit": {
    "command": "npx",
    "args": ["-y", "@dancumberland/kit-mcp@latest"],
    "env": {
      "KIT_API_KEY": "your-kit-api-key"
    }
  }
}
