Resend for Claude, Cursor, ChatGPT & agents

Resend — send transactional emails (HTML + plain-text fallback) from a verified domain, list previously sent emails, fetch a single email's status, and list verified sending domains

curl -fsSL https://syncorelabs.ai/install.sh | sh

What it does

Resend — send transactional emails (HTML + plain-text fallback) from a verified domain, list previously sent emails, fetch a single email's status, and list verified sending domains. Use when the user mentions Resend, transactional email, magic link, password reset, receipt, signup confirmation, or wants to send programmatic email from their app domain.

The Resend skill is one of 75+ pre-wired Syncore integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the Syncore daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once Syncore is installed and Resend is connected, ask your agent something like:

• “Send email from Resend.”
• “List emails from Resend.”
• “Get email from Resend.”

Tools available (4)

• resend__send_email

  Send / fire / dispatch a transactional email via Resend with HTML + text fallback, optional cc / bcc / reply_to. Use when the user wants to send mail from a verified domain — magic link, password reset, receipt, etc. The sender (`from` / `from_email` / `from_address` — all aliased) must use a verified domain.

• resend__list_emails

  List recently sent Resend emails for the API key. Use when the user wants to audit / review what's been sent or check delivery activity.

• resend__get_email

  Fetch details / status of a single Resend email by email_id (delivered, bounced, complained, opened, clicked). Use when the user wants to check whether a specific message landed or troubleshoot delivery.

• resend__list_domains

  List the sending / verified domains configured on the Resend account. Use when the user wants to confirm DKIM / SPF / DMARC status or pick a from_address.
