# 🚀 Mailchimp MCP Server — 2026 Complete Version
## 💡 What This Unlocks
**This MCP server gives AI direct access to your entire Mailchimp workspace.** Instead of clicking through interfaces, you just *tell* it what you need.
### 🎯 Mailchimp-Native Power Moves
The AI can directly control your Mailchimp account with natural language:
- **Smart automation** — Complex workflows in plain English
- **Data intelligence** — Query, analyze, and export your Mailchimp data
- **Rapid operations** — Bulk actions that would take hours manually
- **Cross-platform integration** — Combine Mailchimp with other tools seamlessly
### 🔗 The Real Power: Combining Tools
AI can chain multiple Mailchimp operations together:
- Query data → Filter results → Generate reports
- Search records → Update fields → Notify team
- Analyze metrics → Create tasks → Schedule follow-ups
## 📦 What's Inside
**85 API tools** covering the entire Mailchimp platform (Email Marketing).
All with proper error handling, automatic authentication, and TypeScript types.
## 🚀 Quick Start
### Option 1: Claude Desktop (Local)
1. **Clone and build:**
```bash
git clone https://github.com/BusyBee3333/Mailchimp-MCP-2026-Complete.git
cd mailchimp-mcp-2026-complete
npm install
npm run build
```
2. **Get your Mailchimp API credentials** (see Authentication section below)
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 your Mailchimp API credentials 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-key \
mailchimp-mcp
```
## 🔐 Authentication
See the official [Mailchimp API documentation](https://docs.mailchimp.com) for authentication details.
The MCP server handles token refresh automatically.
## 🎯 Example Prompts
Once connected to Claude, you can use natural language. Examples:
- *"Show me recent activity in Mailchimp"*
- *"Create a new record with these details..."*
- *"Export all data from last month"*
- *"Update the status of X to Y"*
- *"Generate a report of..."*
## 🛠️ Development
### Prerequisites
- Node.js 18+
- npm or yarn
- Mailchimp account with API access
### Setup
```bash
git clone https://github.com/BusyBee3333/Mailchimp-MCP-2026-Complete.git
cd mailchimp-mcp-2026-complete
npm install
cp .env.example .env
# Edit .env with your Mailchimp credentials
npm run build
npm start
```
### Testing
```bash
npm test # Run all tests
npm run test:watch # Watch mode
npm run test:coverage # Coverage report
```
## 🐛 Troubleshooting
### "Authentication failed"
- Verify your API credentials are correct
- Check that your API key hasn't been revoked
- Ensure you have the necessary permissions
### "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)
