SendKit provides a built-in MCP (Model Context Protocol) server that lets AI coding assistants manage your email infrastructure directly. Your AI assistant can create domains, manage contacts, send emails, and more — all through natural language.

What is MCP?

MCP is an open protocol that connects AI assistants to external tools and data sources. Instead of copying and pasting API calls, your AI assistant can interact with SendKit directly.

Available tools

SendKit exposes 60 tools across 13 categories:

How it works

1

Get your API key

Create an API key from the SendKit dashboard. You need a Full permission key.
2

Configure your AI assistant

Add the SendKit MCP server to your assistant’s configuration using the server URL and your API key.
3

Start using natural language

Ask your assistant to manage your SendKit account. For example: “Create a new sender called Support on my domain” or “List all contacts subscribed to the newsletter list.”
