About

Mailchimp Audiences (BYOK) lets an AI assistant read your own Mailchimp Audiences data through the Mailchimp Audiences API with a key you supply (API key (its suffix after the hyphen is your server prefix)). Read-only: 9 tools (get_audience, list_growth_history, get_growth_month, list_interest_categories, list_category_interests, list_merge_fields, list_audience_webhooks, list_top_email_clients, list_subscriber_locations). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to *.api.mailchimp.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mailchimp Audiences. Mailchimp Audiences and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the Mailchimp Audiences API (*.api.mailchimp.com) with a BYOK key; documentation: https://mailchimp.com/developer/marketing/api/lists/get.md. Endpoints checked against that documentation on 2026-10-16.

BYOK: bring your own keyThis connector uses your own Mailchimp Audiences API key (its suffix after the hyphen is your server prefix). Create one at https://mailchimp.com/help/about-api-keys/, with the fewest permissions it needs (read-only if the provider offers it). Your assistant sends it in the X-Upstream-Key header with every request. It is used for that one call only: never stored, logged or cached, and only ever sent to Mailchimp Audiences. Revoke it at the provider whenever you like. Unofficial connector: not affiliated with Mailchimp Audiences.
