Standardize Email Functions Across Your Team

Define your MailerSend connection in the project's `.vscode/mcp.json` file and commit it to your repository. This is the key. Once that file is in place, every developer on the team gets the same MailerSend tools in Copilot automatically. When a teammate asks the agent to 'send an order confirmation,' it uses the same shared configuration for the `send_templated_email` tool. This ensures consistency across the entire codebase and eliminates the 'works on my machine' problem for email integrations.

Pull Live Analytics into Code Comments

While reviewing a function that triggers a marketing email, you can ask Copilot's agent, "What were our open rates yesterday?" There's no need to switch to a dashboard or ask someone on the marketing team. The agent will call `get_date_analytics` on your MailerSend account and drop the stats right into a comment block in the code. This gives your team immediate context on performance, helping you make better decisions right where the code is written.

Verify Domain Setups in VS Code Copilot

Before deploying a new service that sends email, you can ask the agent to verify your production domain is ready to go. A simple prompt like, "Check our sending domains in MailerSend," is all it takes. It uses `list_sending_domains` to check for verification and `list_domain_webhooks` to confirm your endpoints are configured for bounce events. This simple check inside the editor makes the MCP Server a critical part of your team's pre-flight checks, preventing common deployment errors.

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.
2

Add the MailerSend MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the MailerSend tools listed. Try asking: "List my recent MailerSend transactions" and Copilot will invoke them automatically.

Common questions about MailerSend MCP in VS Code Copilot

Create a `.vscode/mcp.json` file in your project's root directory and add the server details there. Commit that file to your Git repository, and every team member using Copilot in that project will have the tools.

Yes. Just provide a message ID to the agent and ask for its status. Copilot will use the `get_message_info` tool to fetch the full delivery history from your MailerSend account.

It's about shared context. The whole team gets the same tools through a single config file in the repo. This ensures everyone is building against the same live MailerSend environment without needing individual setup or API keys.

Open the Copilot chat, switch to agent mode, and ask it to "List all email templates in MailerSend." It will run the `list_email_templates` tool and give you a list of template names and IDs you can use in your code.

Only the specific data needed for a tool to run is transmitted, like a recipient's email for `send_transactional_email` or a date range for `get_date_analytics`. Your organization's Vinkius account manages the connection, handling authentication without exposing API keys to individual developers' machines.
