Mailchimp MCP Server
The most complete Model Context Protocol (MCP) server for the Mailchimp Marketing API: 227 tools to query and manage your Mailchimp account from any MCP-compatible client. It covers the full campaign, audience, member, segment, automation and reporting surface, complete e-commerce (read and write), landing pages, File Manager, surveys, signup forms and verified domains, plus multi-account support and runtime-security guardrails (read-only, dry-run and audit modes, with per-tool risk metadata).
Uses the Mailchimp Marketing API via requests. Not based on the official mailchimp-marketing-python client. I hit too many issues with it so I went with raw HTTP calls instead.
