  "summary": "Mailchimp is automatable today through the Marketing REST API and the Transactional API. Marketing API v3.0 lives at https://<dc>.api.mailchimp.com/3.0/ and authenticates with an API key or an OAuth 2.0 access token, using HTTP Basic or Bearer. Coverage is plan-gated. Official client libraries for Marketing and Transactional are listed for Python and Ruby. Transactional (Mandrill) is a mostly-REST POST API at https://mandrillapp.com/api/1.0/ authenticated with an API key in the JSON body. Full Transactional use needs a Standard or Premium account. First-party MCP is the hosted Transactional server at https://mandrillapp.com/mcp with a Bearer Transactional API key. Restricted keys need the AI Agents permission group. Tools include call_api, list_api, describe_api, and onboarding helpers. A first-party Marketing MCP was not declared on the opened Marketing API pages. Audience webhooks can be HMAC-signed. mailchimp.com/llms.txt is a site-content analysis dump, not agent documentation. This record excludes Klaviyo and Braze. Connector catalogs and a product CLI were not established. Computer-use viability is unassessed. API scores 8 and is the best path because it covers Marketing and Transactional; MCP covers Transactional only.\n"
