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.
Other Kit MCP servers wrap each API endpoint as a separate tool (29+ tools). That approach breaks in practice:
| @dancumberland/kit-mcp | Other Kit MCPs | |
|---|---|---|
| Tool count | 13 composite tools (45 actions) | 29+ individual tools |
| Engagement analytics | Per-subscriber open/click rates, batch comparison across 100 subscribers, engagement-based filtering | None |
| Broadcast analytics | Per-broadcast stats, cross-broadcast comparison, per-link click tracking | Basic list/get only |
| Bulk operations | Batch create subscribers, tags, form subscriptions (up to 10k per call) | None |
| Response format | Formatted text summaries (agent-friendly) | Raw JSON (agent must parse) |
| Rate limiting | Sliding window with automatic retry + exponential backoff | None |
| Error recovery | Typed errors with actionable recovery hints | Generic errors |
| Cursor compatible | 13 tools (well under 40-tool limit) | 29+ tools (risks hitting limit) |
| Token overhead | ~3,200 tokens for all tool definitions | ~8,000+ tokens |
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.
Connects any MCP client (Claude Desktop, Claude Code, Cursor, Windsurf, etc.) to your Kit.com email marketing account. Ask questions naturally:
No coding required — just set it up and start talking.
node --version.kit_.Mac:
open ~/Library/Application\ Support/Claude/
Open claude_desktop_config.json in any text editor.
Windows:
%APPDATA%\Claude\claude_desktop_config.json
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.
Fully quit (not just close the window) and reopen.
