Mailchimp + ChatGPT
Drive Mailchimp's Marketing API from any AI agent: audiences (lists), members, tags, campaigns, templates, segments and account info. 16 ready-to-use tools. Bearer-token auth with a datacenter-prefixed base URL.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
MAILCHIMP_API_KEY, MAILCHIMP_DC
Step 1 — Get credentials
Datacenter-prefixed base URL (Mailchimp-specific quirk): each account lives on a numbered datacenter — us1, us2, … us21, etc. — and the API URL embeds it: https://us{N}.api.mailchimp.com/3.0. The datacenter suffix is the last segment of your API key after the dash (so an API key with -us6 at the end lives on us6). The adapter takes the datacenter as an env var MAILCHIMP_DC and substitutes it into the base URL — if you set the wrong DC you'll get 404 NotResolved errors.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Mailchimp. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ
Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
