Mailchimp is Intuit's email marketing and customer engagement platform. It provides tools for managing audiences, campaigns, automations, and transactional messaging.
Mailchimp exposes two documented HTTP APIs for developers—the Marketing API and Transactional API—and a cataloged streamable HTTP MCP server endpoint for Intuit Mailchimp.

Sign in to your Mailchimp account, open the API Keys section, click Create New Key, name it, and copy the generated key immediately. The key grants full account access and is shown only when created; Mailchimp's quick start and fundamentals docs say it is required for direct access to your own account's Marketing API data.
To access other users' Mailchimp Marketing data, register an app from the Registered Apps page, click Register An App, complete the form, and save the client_id and client_secret. Then run the OAuth 2 authorization-code flow described in the OAuth guide to obtain a bearer access token. The guide states Mailchimp Marketing access tokens do not expire unless revoked.
Create a Mailchimp Transactional account, then open the SMTP & API Info page to view your credentials. Mailchimp's SMTP docs state you can use any active API key for your account as your SMTP password, and the same key is used for the Transactional API.
