Mailchimp for AI agents

Mailchimp is an email marketing platform businesses use to run campaigns, segment audiences, and track engagement across a subscriber list. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

01 · USE CASES

What agents do in Mailchimp.

01

Add a contact to an audience

Add a new contact to a list after they sign up on another channel.

02

Check a campaign's performance

Pull open and click stats for a recent campaign to report on results, read-only.

Approve a campaign before sending

Require sign-off before a campaign goes out, since it reaches the entire audience.

02 · ACTIONS

275 Mailchimp actions, graded by risk.

await arc0.policies.set('mailchimp', {
  read: 'allow',
  write: 'ask',        // update_cart

04 · AUTH AND DATA

How Mailchimp connects.

Users sign in to Mailchimp on Arc0 Connect and approve the scopes you request. Build with Arc0’s Mailchimp OAuth app, or bring your own so the Mailchimp consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Mailchimp connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Mailchimp and Arc0, answered.

Q01

Can I use Mailchimp with Claude, ChatGPT or Cursor?

Yes. Connect Mailchimp to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Mailchimp actions you allow.

Q02

How do users connect Mailchimp?

Users sign in to Mailchimp on Arc0 Connect and approve the scopes you request. Build with Arc0’s Mailchimp OAuth app, or bring your own so the Mailchimp consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Mailchimp actions can my agent take?

275 in total: 141 read, 87 write and 47 destructive, such as “update cart”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Mailchimp?

Yes. Actions like “delete cart” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Mailchimp too?

Yes. The same Mailchimp connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
