Resend MCP Server

What it does

Resend MCP Server connects AI agents to the Resend email platform, enabling them to send individual and broadcast emails, manage contacts and segments, track campaign delivery, and handle subscription preferences — all through natural conversation. It abstracts away the complexity of the Resend API so agents can work with human-friendly identifiers like segment names and email addresses instead of UUIDs.

Tools

• upsert_contacts — Add or update contacts in bulk (up to 100 per call), assign to segments
• remove_contacts — Permanently delete contacts by email
• find_contacts — Search and filter contacts with pagination, filter by segment or subscription status
• segments — Create, list, delete segments and manage segment membership
• send — Send individual emails or broadcast newsletters to a segment, with template support and personalization variables
• campaigns — View campaign history, check delivery stats (sent, delivered, opened, failed), cancel scheduled sends
• subscriptions — Subscribe or unsubscribe contacts to topics, including global unsubscribe
• templates — List available email templates with their variables and fallback values
