Nextmail MCP Server

What it is

Nextmail's official MCP server connects an agent to the user's Nextmail mailbox. Agents can find and read conversations, search mail, draft replies and send them after the user confirms, organise threads with labels, and keep contacts and calendars up to date. It works in Claude, ChatGPT, Cursor, VS Code, Codex, Gemini CLI or any MCP client, and the person chooses which workspace and permissions the client gets when they connect. A free plan is available.
