Resend Email MCP
Wire transactional and product email through Resend from your agent, with deliverability and bounce debugging in the same MCP session.
Overview
Resend Email MCP is a MCP server for the Build phase that wraps the Resend email API and adds deliverability, DNS, and bounce debugging tools for agent-driven integration work.
What is this MCP server?
- Full Resend API coverage for send, domains, audiences, and batch operations
- Debug layer for deliverability, DNS verification, and bounce investigation
- RESEND_READONLY blocks mutating tools for safer staging and audits
- Configurable RESEND_FROM and RESEND_REPLY_TO defaults for consistent agent sends

- Documented full Resend API coverage plus dedicated debug layer

What problem does it solve?
You added Resend to your app but debugging domain records and failed sends still means context-switching to the dashboard and docs.
Who is it for?
Solo SaaS builders using Resend who want agents to implement and troubleshoot email without leaving the IDE.
Skip if: Teams on SendGrid-only stacks, bulk cold-email workflows, or builders who need a visual drag-and-drop newsletter designer only.
What do I get? / Deliverables
Once configured with RESEND_API_KEY and verified RESEND_FROM, your agent can send mail, manage Resend resources, and run debug checks from the same MCP connection.
- Agent-driven Resend sends and resource management
- Deliverability and DNS debug actions from MCP tools
- Safer runs via RESEND_READONLY and scoped attachments dir
Recommended MCP Servers
Journey fit
Resend is integrated while you are building auth flows, receipts, and onboarding email—classic Build integrations—even though marketers use it later in Grow. Sending mail, domains, templates, and webhooks are third-party product integrations, not copywriting or SEO, so integrations fits better than launch or content subphases.
How it compares
Resend-focused API and deliverability MCP, not a marketing copy skill or inbox IMAP connector.
