Mailchimp MCP Server is a read-only MCP server that exposes the Mailchimp Marketing API v3 to MCP clients, enabling comprehensive retrieval of email marketing data. It supports endpoints across Automation Management, Automation Email Management, Subscriber Management, List Management, Campaign Management, Member Management, Segment Management, Template Management, as well as Reports and Analytics, Account Information, Folder Management, File Manager, Landing Pages, E-commerce, Conversations, and Merge Fields. Access requires a Mailchimp API key (MAILCHIMP_API_KEY) with the data center suffix, as described in the README. It is designed to work with any MCP client and can be configured via the provided example MCP settings block. The project ships as the npm package @agentx-ai/mailchimp-mcp-server and provides a local development workflow (clone, npm install, npm run build) and an API reference pointing to Mailchimp's documentation. The MCP server is read-only and aims to give secure, read-only access to Mailchimp data for integration, analytics, and tooling via MCP clients. It is licensed under the MIT License.
