How to Use the MailerSend MCP in VS Code Copilot

Q: Can VS Code Copilot handle bulk email dispatches with MailerSend?

Yes. Copilot can call sendbulktransactionalemails to run batch tests on staging environments using your team's configured templates.

Q: How do we verify our staging domains using MailerSend and VS Code Copilot?

Ask Copilot to check the domain status. It will use getsenderdomaindetails and print the exact DNS records that your team needs to add to your registrar.

Q: Can we track real-time delivery logs inside VS Code?

Yes. Copilot can pull recent delivery events using listdomainactivity and display them directly in the chat window, saving you a trip to the web console.

Give your team-wide VS Code Copilot MCP client the power to send and track MailerSend emails.

Team-wide transactional email testing in VS Code Copilot

Commit your MailerSend MCP configuration directly to your repo using `.vscode/mcp.json`. This gives every developer on your team immediate access to MailerSend's `send_transactional_email` inside VS Code Copilot for testing notification pipelines. Instead of sharing a single testing API key or logging into the MailerSend dashboard, developers can trigger test runs directly through the VS Code Copilot chat interface.

Automated domain verification checks for dev teams

Keep your staging and production MailerSend domains in sync across the entire engineering team inside VS Code. VS Code Copilot can list all configured domains using `list_sender_domains` to ensure staging environments are pointing to verified MailerSend senders. When setting up a new microservice, developers can run `verify_sender_domain` through VS Code Copilot to confirm that MailerSend DNS propagation is complete. Running this tool lets your team confirm DNS configuration before deploying.

Inspect recipient status and activity logs

Let your team debug MailerSend delivery complaints directly from their VS Code workspace. VS Code Copilot queries `get_recipient_details` and `list_email_recipients` to verify if a MailerSend recipient has opted out or bounced. By retrieving MailerSend details via `get_sent_message_details`, VS Code Copilot developers can quickly isolate whether a delivery failure was due to an invalid email address or a template syntax error.

Setup guide

Set up MailerSend MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
