Installation

Using uvx (recommended)

No installation needed — run directly:

uvx mailchimp-mcp-server

Using pip

pip install mailchimp-mcp-server

Then run:

mailchimp-mcp-server

From source

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.
