How do I send emails using this MCP?

You can tell your AI client to send an email by providing the sender, recipient, and subject. You can also include HTML bodies and attachments.

Can I manage my domains through the AI?

Yes. You can add new domains, get the required DNS records, and verify them once they are added to your DNS provider.

Is it possible to cancel an email I already scheduled?

Yes, as long as the email is still in 'scheduled' status, you can use the cancel capability with the email ID.

How secure is the API key management?

You can create scoped keys with specific permissions like 'sending' or 'domains' only, limiting what the AI can do.

What happens if I delete an API key?

Deleting an API key is irreversible and will immediately stop any service using that specific key from authenticating.

How do I create a Resend API Key?

Log in to the Resend Dashboard, go to Settings > API Keys, click Create API Key, select the permission scope (Full Access, Sending, or Domains), give it a name and copy the key immediately. it starts with re_ and won't be shown again.

Can I send HTML emails with attachments?

Yes! Use the send_email capability with the html parameter for HTML body content and optionally include attachments. You can also provide a text fallback for email clients that don't render HTML. Attachments are passed as objects with filename, content (base64) and content_type.

How do I verify a domain for sending?

Use create_domain with your domain name (e.g. "example.com"). Resend will return the SPF and DKIM DNS records you need to add to your DNS provider. After adding the records, use verify_domain with the domain ID to trigger re-verification. The domain status will change to "verified" once DNS propagation is complete.

What are the API rate limits?

Resend allows 5 requests per second per team, shared across all API keys. If you exceed this limit, you'll receive a 429 response. Rate limits can be increased by contacting Resend support for verified senders.

MCP VERIFIED · PRODUCTION READY · VINKIUS GUARANTEED

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

One connector, every AI

Resend works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Resend to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Resend, so you can see the experience inside your AI.

It does not authenticate your account with Resend. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
