Connect Windsurf to your emails

Why connect Windsurf to your emails?

Windsurf by Codeium is designed for developers who want deep AI integration in their editor. Its Cascade feature already helps you write and refactor code through conversation. But when you need to check an email, reply to a project update or follow up with a client, you still have to leave the editor and break your flow.

With MailMCP, Windsurf becomes your communication hub too. Ask Cascade to list your unread emails, find a specific message, compose a reply or schedule an email for Monday morning. Everything happens inside the editor, using the same conversational interface you already know.

MailMCP connects your IMAP/SMTP mailbox to Windsurf via the MCP protocol. Configuration takes under 2 minutes: edit a single JSON file and Cascade picks up the new tools automatically. No plugin, no build step, no server to maintain.
