## Description
MCP server for Kit.com (ConvertKit) - manage subscribers, tags, sequences, broadcasts

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "mcp-kit": {
    "command": "npx",
    "args": ["-y","mcp-kit"]
  }
}
```

[![Status: Deprecated](https://img.shields.io/badge/status-deprecated-red.svg)](#deprecated--use-kits-official-mcp-servers)

An MCP (Model Context Protocol) server that connects AI assistants like Claude to the [Kit.com](https://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 **This project is deprecated and no longer maintained.** Kit now ships official, first-party MCP servers that supersede it with broader API coverage and managed authentication.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.**

| Use case | Official server | URL |
|----------|-----------------|-----|
| Act on your Kit account — subscribers, tags, sequences, broadcasts, **analytics**, commerce… | **Kit MCP** | `https://app.kit.com/mcp` |
| Give a coding agent live access to Kit's developer docs + API | **Kit Developer Docs MCP** | `https://developers.kit.com/mcp` |

### Migrate in Claude Code

```bash
# Remove this deprecated server (if you added it as "kit")
claude mcp remove kit

# Add the official operational Kit MCP
claude mcp add --transport http kit https://app.kit.com/mcp

# Optional: add Kit's developer-docs MCP for building integrations
claude mcp add --transport http kit-docs https://developers.kit.com/mcp
```

```json
{
  "mcpServers": {

## Troubleshooting

### "KIT_API_KEY environment variable is required"
Ensure you have set the `KIT_API_KEY` environment variable in your MCP configuration.

### "Kit API error (401)"
Your API key is invalid or expired. Generate a new one from Kit.com Settings > Developer.

### "Kit API error (403)"
Your API key doesn't have permission for this operation. Check that you're using a v4 API key with appropriate scopes.

### "Kit API error (404)"
The resource (subscriber, tag, broadcast, etc.) was not found. Verify the ID is correct.

### "Kit API error (422)"
Invalid request data. Check that email addresses are valid and required fields are provided.
