Mailchimp MCP Server

License: MIT Python 3.10+ MCP

A Model Context Protocol (MCP) server for the Mailchimp Marketing API. 74 tools to query and manage your Mailchimp account directly from Claude.

Uses the Mailchimp Marketing API via requests. Not based on the official mailchimp-marketing-python client. I hit too many issues with it so I went with raw HTTP calls instead.

Prerequisites

Python 3.10+
A Mailchimp API key

Installation

Using `uvx` (recommended)

No installation needed — run directly:

uvx mailchimp-mcp

Using `pip`

pip install mailchimp-mcp

Then run:

mailchimp-mcp

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.

Claude Desktop

Add this to your claude_desktop_config.json:

Windows (Microsoft Store): If Claude Desktop was installed via the Microsoft Store, the config file is located at C:\Users\<user>\AppData\Local\Packages\Claude_<id>\LocalCache\Roaming\Claude\claude_desktop_config.json instead of the usual %APPDATA%\Claude\ path.
