# 📧 Mailchimp MCP Server

## 💡 What This Unlocks

**This MCP server gives AI direct access to your entire Mailchimp marketing operation.** Instead of clicking through campaigns and lists, you just *tell* it what you need.

### 🎯 Mailchimp-Native Power Moves

| Just say... | What happens |
|-------------|--------------|
| *"Show me subscribers who opened the last campaign but didn't click"* | Queries campaign reports, filters engaged users, returns contact list with engagement scores |
| *"Create a welcome email campaign for new subscribers with 15% off code"* | Builds campaign, designs template, adds coupon, schedules send |
| *"Which audience segments have the highest open rates this month?"* | Pulls analytics, compares segment performance, generates ranked report |
| *"Add everyone from webinar-attendees.csv to the VIP list and tag them"* | Imports contacts, assigns to audience, applies tags, updates preferences |
| *"Draft a product launch email and schedule for Thursday 9am EST"* | Creates campaign, generates content, sets timezone, schedules delivery |

### 🔗 The Real Power: Combining Tools

AI can chain multiple Mailchimp operations together:

- **Smart Segmentation:** *"Find subscribers who joined in the last 30 days and have opened at least 2 emails"* → Query audiences, filter by join date and engagement, create segment
- **Campaign Optimization:** *"Compare subject lines from my last 5 campaigns and suggest improvements for tomorrow's send"* → Pull campaign data, analyze open rates, generate recommendations
- **List Health:** *"Show me contacts who haven't engaged in 90 days and create a re-engagement campaign"* → Identify inactive users, build win-back sequence, schedule drip

## 📦 What's Inside

**85 API tools** covering the entire Mailchimp platform:

- **Campaigns** — Create, send, schedule, test, and analyze email campaigns
- **Audiences** — Manage lists, segments, merge fields, and tags
- **Contacts** — Add, update, delete, and search subscribers
- **Templates** — Design and manage email templates
- **Automations** — Set up drip campaigns and triggered emails
- **Reports** — Campaign analytics, engagement metrics, revenue tracking

All with proper error handling, automatic rate limiting, and TypeScript types.

## 🚀 Quick Start

### Option 1: Claude Desktop (Local)

1. **Clone and build:**
   ```bash
   git clone https://github.com/YOUR_USERNAME/mailchimp-mcp.git
   cd mailchimp-mcp
   npm install
   npm run build
   ```

2. **Get your Mailchimp API key:**
   - Go to [Mailchimp Account Settings](https://admin.mailchimp.com/account/api/)
   - Click "Create A Key"
   - Copy the API key (starts with your username and ends with `-us##`)

3. **Configure Claude Desktop:**
   
   On macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
   
   On Windows: `%APPDATA%\Claude\claude_desktop_config.json`

   ```json
   {
     "mcpServers": {
       "mailchimp": {
         "command": "node",
         "args": ["/ABSOLUTE/PATH/TO/mailchimp-mcp/dist/index.js"],
         "env": {
           "MAILCHIMP_API_KEY": "your-api-key-here"
         }
       }
     }
   }
   ```

4. **Restart Claude Desktop**

### Option 2: Deploy to Railway

[![Deploy on Railway](https://railway.app/button.svg)](https://railway.app/template/mailchimp-mcp)

1. Click the button above
2. Set `MAILCHIMP_API_KEY` in Railway dashboard
3. Use the Railway URL as your MCP server endpoint

### Option 3: Docker

```bash
docker build -t mailchimp-mcp .
docker run -p 3000:3000 \
  -e MAILCHIMP_API_KEY=your-api-key \
  mailchimp-mcp
```

## 🔐 Authentication

Mailchimp uses API key authentication:

1. **Log in to Mailchimp**
2. **Navigate to:** Account → Extras → API Keys
3. **Click:** "Create A Key"
4. **Copy the key** (format: `username-md5hash-us##`)

The API key includes your datacenter (e.g., `us19`) — the MCP server automatically extracts this.

## 🐛 Troubleshooting

### "Authentication failed"
- Verify your API key is correct (should include datacenter like `-us19`)
- Check that your API key hasn't been revoked in Mailchimp settings
- Ensure you copied the entire key including username prefix

### "Rate limit exceeded"
- Mailchimp has rate limits (typically 10 requests/second)
- The MCP server automatically handles retries
- For bulk operations, reduce concurrency

### "Tools not appearing in Claude"
- Restart Claude Desktop after updating config
- Check that the path in `claude_desktop_config.json` is absolute
- Verify the build completed successfully (`dist/index.js` exists)

### "Audience not found"
- Audience IDs are case-sensitive
- Use `list_audiences` to get the correct ID
- Some operations require admin-level API keys
