Mailchimp MCP: connect it to Claude Code, plus ready-made skills
Pull opens, clicks, unsubscribes and bounces for each Mailchimp campaign plus audience growth, and report how the last send did against your usual numbers.
How to connect Mailchimp MCP to Claude Code, Codex or Cursor
- Intuit Mailchimp connector in Claude. Mailchimp's own connector (
https://ai-inc.mailchimp.com/claude/mcp/v2) is in Claude's connector directory. It plans, edits and saves campaigns as drafts and uses your past performance for its suggestions, but Mailchimp describes it as focused on campaign planning, not on pulling reports, and connecting it takes an Owner or Admin role (help). - Marketing API with an API key. Mailchimp doesn't document a general MCP server for Claude Code, Codex or Cursor, so scheduled reports call the API. Create a key on your account's API keys page, store it in
MAILCHIMP_API_KEY, and read the data center from its suffix (...-us6meanshttps://us6.api.mailchimp.com/3.0). Send it with HTTP Basic auth (any username, the key as the password) or as a Bearer token. The API allows 10 simultaneous connections, so page through reports one request at a time.
API keys can't be limited to read-only: a key acts with the role of the user who created it, so keep it in a secret store, use it only for GET requests, and revoke it when the report is retired.

What agents do with Mailchimp
Agents read Mailchimp through the Marketing API at https://<dc>.api.mailchimp.com/3.0, where <dc> is the data center at the end of your API key, such as us6. GET /reports returns one report per sent campaign with emails_sent, opens.unique_opens, opens.open_rate, clicks.click_rate, unsubscribed and bounces.hard_bounces, and GET /reports/{campaign_id}/click-details lists the links people clicked. For audiences, GET /lists/{list_id} carries stats.member_count, stats.unsubscribe_count and average open and click rates, and GET /lists/{list_id}/growth-history gives subscribed, unsubscribed and cleaned counts by month. GET /campaigns?status=sent&since_send_time=... finds what went out in a period.
Marketers schedule a report a day or two after each send (open and click rate against the last ten campaigns, top links, unsubscribes), weekly audience growth with unsubscribes and cleaned contacts, and an alert when hard bounces or unsubscribes on a send jump. Apple Mail Privacy Protection inflates opens, so most reports lead with clicks.
