description Overview

mcp-resend — Resend MCP Server

Send transactional emails and manage domains from your AI agents.

Resend is the developer-first email platform built for reliable transactional delivery — welcome emails, password resets, invoice notifications, and anything else your product needs to send. This MCP server lets your AI agents send emails, check delivery status, list recent sends, and inspect verified sending domains without touching code.

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-resend

What You Can Do

  • Send transactional emails (HTML or plain text) from agent workflows — triggered by signups, payments, alerts, or any event
  • Check the delivery status of a previously sent email by ID to confirm it was received
  • List recent emails to audit what has been sent and identify delivery issues
  • List verified sending domains to confirm which domains are authorized before sending

Available Tools

Tool Description
send_email Send a transactional email (HTML or plain text, supports CC, BCC, reply-to)
get_email Get details and delivery status of a sent email by ID
list_emails List recently sent emails
list_domains List verified sending domains
cancel_email Cancel a scheduled email before it sends

Configuration

Variable Required Description How to Get
RESEND_API_KEY Yes Resend API key for all email operations resend.com/api-keys → Create API Key → give it a name and set permissions → copy the key (shown once)

Quick Start

Add to Aerostack Workspace
  1. Go to aerostack.dev → Your Project → MCPs
  2. Search for "Resend" and click Add to Workspace
  3. Add your RESEND_API_KEY under Project → Secrets

"Check the delivery status of the email with ID email_abc123xyz"

Frequently asked questions

What is the Resend MCP server and what can it do? +

The Resend MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `send_email`, `get_email`, `list_emails`, `list_domains`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.

Is the Resend MCP server hosted, or do I have to run it myself? +

It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.

Which AI agents and editors can use the Resend MCP server? +

Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same Resend MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.

How do I install the Resend MCP server in Claude Desktop? +

Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-resend": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-resend"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.

How do I use the Resend MCP server in Cursor? +

In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-resend", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-resend"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.

Does Resend MCP require authentication? +

Yes. Resend requires authentication. Check the MCP's documentation for the required credentials.
