Setup

1. Get Your Mailchimp API Key

1. Log in to Mailchimp
2. Click your profile icon → Account & billing
3. Go to Extras → API keys
4. Click Create A Key
5. Give it a name (e.g., "Claude Cowork") and copy the key

The key looks like: abc123def456ghi789-us21

The part after the dash (us21) is your data center — the server uses this automatically.

2. Build the Server

cd mailchimp-mcp-server
npm install
npm run build

3. Configure Claude

For Claude Desktop / Cowork

Add this to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

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

Replace /FULL/PATH/TO/ with the actual absolute path to this folder, and paste your real API key.

For Claude Code

Add to your project's .mcp.json:

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

4. Restart Claude

After saving the config, restart Claude Desktop (or reload Claude Code) so it picks up the new MCP server.
