MailerSend MCP Server

The MailerSend Model Context Protocol (MCP) server provides seamless integration with MailerSend's API. This server enables AI assistants to send emails and SMS, manage domains, templates, webhooks, suppressions, sender identities, users, and many other things through standardized MCP tools.

The Model Context Protocol (MCP) is a standardized protocol for AI assistants to interact with external systems. Think of it as USB-C port for AI. You can connect multiple MCPs that talk to each-other and get things done for you.

You can connect any MCP-compatible client to the running server. The server supports a streamable HTTP endpoint up to the latest MCP server specifications. Usually, you would just addhttps://mcp.mailersend.com/mcpas a remote MCP address in any tooling that you are working with.
