Mailchimp

Connects Claude to Mailchimp's marketing automation platform through the Membrane CLI. You get pre-built actions for managing audiences, campaigns, templates, segments, and automations without dealing with OAuth refreshes or credential management. The skill includes popular operations like listing contacts, creating campaigns, and updating member data. When the built-in actions don't cover your needs, you can proxy requests directly to Mailchimp's API with authentication handled automatically. Requires a free Membrane account and works best when you search for actions by intent rather than browsing docs. Most useful for marketing automation tasks where you need Claude to read campaign data or update mailing lists programmatically.
