Permissions and safety

• Read Only connections run reads only. Write actions need Read + Write.
• The 37 actions that delete, archive, remove or cancel, such as delete_list, delete_campaign, archive_member, delete_member_permanent and cancel_campaign, are destructive, so they stay off until an owner, admin or operator enables them in Configure actions for this account.
• send_campaign, schedule_campaign and resend_campaign are regular write actions that are on for Read + Write connections. They email real subscribers, so turn them off where agents should only draft campaigns.
• Writes need the Owner, Administrator or Operator role. Members with the User role can only run enabled read actions on accounts granted to them.

Limits

• The connector uses the Mailchimp Marketing API. It doesn't send transactional email through Mailchimp Transactional.
• Classic automations can be started and paused but not created, and Customer Journeys can be triggered with trigger_customer_journey but not built.
• Mailchimp API rate limits apply. The server retries when Mailchimp asks it to slow down.

Example prompts

• "Using Mailchimp, compare open and click rates for our last 10 campaigns."
• "Which links got the most clicks in yesterday's newsletter?"
• "How did our main audience grow over the last 12 months?"
• "Copy last week's newsletter and schedule the copy for Tuesday at 9am."

Troubleshooting

• "This action is disabled for this connected account. An owner or admin must enable it for the account." An owner, admin or operator can enable it in Configure actions for this account. Destructive actions start off.
• "This account is connected read-only, so this action cannot be enabled for it. An owner or admin must reconnect it with Read & Write permissions." Reconnect and choose Read + Write under Permissions.
• The connection shows Expired or Reconnect required: reconnect it and sign in to Mailchimp again.

FAQ

Is this Mailchimp's official MCP server?

No. Intuit Mailchimp offers its own Claude connector for creating campaigns and a separate MCP server for Mailchimp Transactional. InsightfulPipe is an independent hosted server for the Mailchimp Marketing API, with Read Only connections and per-action controls.

Can an agent send a campaign without asking?

On a Read + Write connection send_campaign is on unless you turn it off. Turn off the send, schedule and resend actions in Configure actions for this account if agents should only prepare campaigns.

Can I connect several Mailchimp accounts?

Yes. Each connection is one Mailchimp account, and each connected account counts as one connection on your plan.
