## Prerequisites

- Python 3.10+
- A [Mailchimp API key](https://mailchimp.com/help/about-api-keys/)

## Installation

### Using `uvx` (recommended)

No installation needed — run directly:

```bash
uvx mailchimp-mcp-server
```

### Using `pip`

```bash
pip install mailchimp-mcp-server
```

Then run:

```bash
mailchimp-mcp-server
```

### From source

```bash
git clone https://github.com/damientilman/mailchimp-mcp-server.git
cd mailchimp-mcp-server
python -m venv .venv
source .venv/bin/activate
pip install -e .
```

## Configuration

| Variable | Required | Description |
|---|---|---|
| `MAILCHIMP_API_KEY` | Yes | Your Mailchimp API key (format: `<key>-<dc>`, e.g. `abc123-us8`) |
| `MAILCHIMP_READ_ONLY` | No | Set to `true` to disable all write operations (default: `false`) |
| `MAILCHIMP_DRY_RUN` | No | Set to `true` to preview write operations without executing them (default: `false`) |

The datacenter (`us8`, `us21`, etc.) is automatically extracted from the key.

### Safety modes

**Read-only mode** — When `MAILCHIMP_READ_ONLY=true`, all write tools (create, update, delete, schedule, etc.) are blocked and return an error. Read tools work normally. This is the recommended default for shared or exploratory setups where you only need reporting and analytics.

**Dry-run mode** — When `MAILCHIMP_DRY_RUN=true`, write tools return a preview of the action they *would* perform (tool name, target resource, parameters) without making any API call. Useful for testing prompts before going live.
