Question : What is the difference between the MCP server and the Mailpro API?

• The Mailpro API is for developers: they write a program that calls precise addresses, with precise parameters.
• The MCP server is for AI assistants: it tells the assistant what it can do, and the assistant uses it when you ask for something in plain language.

The MCP server relies on the API: same data, same rules, same credits. The list of its tools is on the developer portal.
