How do I connect my Mailgun account?

You subscribe to the MCP on Vinkius and provide your Mailgun Private API Key. Once connected, it is ready to use in any compatible client.

Can I send emails through this MCP?

Yes, you can use the send_email capability to dispatch transactional messages from your verified domains.

How do I check if my domain is set up correctly?

You can ask your agent to check the domain health or use the get_domain capability to retrieve DNS records like SPF and DKIM.

What happens if an email bounces?

You can use list_bounces to see the errors and delete_bounce to remove an address from the suppression list if you want to try sending to it again.

Does this work with Claude or Cursor?

Yes, this MCP works with any client that supports the Model Context Protocol, including Claude, Cursor, and Windsurf.

Can I check if my domain's DNS records are correctly configured?

Yes. Use the get_domain capability by providing your verified domain name. Your agent will retrieve the status of SPF, DKIM, and MX records, helping you identify if any DNS dependencies are missing or misconfigured.

How do I see which emails have recently bounced from my domain?

The list_bounces capability allows your agent to extract the suppression logs for a specific domain. You'll see the email addresses that failed to deliver, providing insights into audience health or sending boundaries.

Can my agent validate an email address before I send a message?

Absolutely. Use the validate_email capability to check if an address is valid, deliverable, and doesn't belong to a disposable service. This is perfect for ensuring high-quality data before triggering outbound sends.

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.

Automate a task

Put Mailgun to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Mailgun 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 Mailgun 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 Mailgun, so you can see the experience inside your AI.

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