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.

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 (44 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

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