The newsletter MCP server

Connect ChatGPT, Claude, Cursor or any MCP client to MailCheap. Your agent writes and schedules issues, sends them once you say yes, imports your list and reads the stats, with the dashboard's checks and limits. On every plan.

03 · Sending

Your agent asks before it sends

Sends can't be undone, so the tools that send are marked that way, and their descriptions ask your agent to check with you first. Test emails only go to you.
