What resend does

The plugin bundles five skills for the Resend email service. It includes Resend API integration, an agent-email-inbox mailbox, the resend-cli terminal tool, react-email components, and email-best-practices rules.

It registers a hosted MCP server at https://mcp.resend.com/mcp via streamable HTTP. Tool access uses OAuth authentication on the first connection, so there is no need to enter headers manually.

A Resend account with a verified domain and an API key in RESEND_API_KEY are mandatory. Without a verified domain, message delivery fails immediately.

What it helps with

send transactional messages through the Resend API
build email templates with React Email components
set up a dedicated inbox for coding agents
verify email markup against deliverability rules

Example prompts for the agent

Create an email template using React Email and send a test message via Resend API.
Review this newsletter markup against email deliverability best practices.
Set up an incoming mailbox for the agent with agent-email-inbox.

## MCP Server

The plugin registers Resend's hosted [MCP server](https://github.com/resend/resend-mcp) at `https://mcp.resend.com/mcp` (streamable HTTP), giving agents tool access to the full Resend API. It authenticates via OAuth — your client walks you through sign-in on first connect, so no API key or header configuration is needed.

## Plugins

This repo follows the [Agent Plugins](https://agent-plugins.org) open standard: `plugin.json` and `mcp.json` at the root, skills in `skills/`. Any conformant client can load it.

It also serves as a plugin for these platforms through their own manifests:

- **Claude Code** — `.claude-plugin/`
- **Cursor** — `.cursor-plugin/`
- **Grok** — `.grok-plugin/`

## Editing skills

Skills marked **"Authored here"** can be edited directly in this repo.

Skills marked **"Synced from"** are automatically synced from their source repos. **Do not edit them here** — changes will be overwritten on the next sync. Edit in the source repo instead.

## Prerequisites

- A Resend account with a verified domain
- API key stored in `RESEND_API_KEY` environment variable
