Mailchimp doesn't publish a general-purpose Marketing API MCP server you can install yourself. What it does have is an official Intuit Mailchimp connector inside Claude's connector directory (launched in mid-2026), and a separate official MCP for Mailchimp Transactional (Mandrill) at https://mandrillapp.com/mcp. The Transactional one is for receipts and password resets, not newsletters.

If you use Claude on the web or desktop, turn on the official connector. It reads your campaign history, audiences and engagement patterns, and Mailchimp pitches it as a planning partner: describe a goal like a win-back campaign and it builds the plan around your real open and click data. If you work in Claude Code, Cursor or another MCP client, the open-source AgentX Mailchimp MCP (@agentx-ai/mailchimp-mcp-server) gives you read-only access to campaigns, reports, lists, segments, automations and e-commerce data with one API key.

A workflow that works with either: pull the last 20 campaign reports, have Claude find which segment, send day and subject line style get the best click rate, then draft the next three campaigns around that. You still build and send in Mailchimp.

Caveats. The AgentX server is read-only, which is safe but means Claude can't create anything, and it hasn't had a commit since July 2025. Its automation tools only cover classic automations, because Mailchimp's API doesn't expose the newer automation flows. The official connector's exact tool list isn't published in Mailchimp's docs, so check what it asks for when you connect.

Official vs community Mailchimp MCP

Intuit Mailchimp connector for Claude

For most marketers the official connector is the right pick: one click, OAuth, and it knows your campaign history. Its downside is that it lives in Claude's connector directory rather than as a documented MCP URL, so you can't point Cursor or a custom agent at it. That's where the AgentX server fits. Use the Transactional MCP only if you send transactional email through Mandrill.

What you can ask it

“Pull the reports for my last 20 campaigns. Which send day and subject line style get the best click rate?”
“Which audience segments have the lowest open rate over the last 90 days? Suggest a re-engagement plan for the worst one.”
“I need a post-holiday win-back plan for buyers who haven't purchased in 90 days. Base it on how my past campaigns performed.”
“List my classic automations and show the open and click rate for each email in the welcome series.”
“Compare this month's campaign click rates to the same month last year.”

FAQ

Is there an official Mailchimp MCP server?

Sort of. Intuit Mailchimp has an official connector in Claude's connector directory and an official MCP for Mailchimp Transactional (Mandrill). There's no self-install MCP server for the Marketing API from Mailchimp, so Claude Code users rely on community servers.

How do I connect Mailchimp to Claude?

Open Settings > Connectors in Claude, find Intuit Mailchimp, click Connect and sign in to Mailchimp. For Claude Code, add the AgentX server with your Mailchimp API key.

Can the Mailchimp MCP send campaigns?

The AgentX server can't; it's read-only. Mailchimp's own write-up describes the official connector as a planning tool, with sending finished inside Mailchimp.

Is the Mailchimp MCP free?

Yes. The connector and the open-source servers cost nothing; you pay for Mailchimp and your AI plan.
