Real-time MailerCheck MCP Server queries

Running `verify_single_email` checks problematic addresses directly in your editor to find dead MX records. Your AI client can simply ping the endpoint and return the exact failure reason. This cuts out the middleman. You do not have to open a browser, log into a dashboard, or write a custom cURL script just to check one user.

Handle bulk validation tasks

Executing `create_verification_batch` handles data migrations by passing JSON arrays to the validation backend. The job runs in the background while you keep working on the script. When you are ready, call `list_verification_batches` to find your job ID. Then have the MCP server fire `get_batch_results` to pull the clean data straight into your workspace.

Monitor team API usage

Monitoring team API usage via `get_account_info` shows exactly how many credits your organization has left. Ask Copilot to execute the tool to read your limits. Knowing your balance prevents unexpected rate-limiting errors in staging. It gives you a clear picture of your budget before you trigger a massive list sweep.

Setup guide

Set up MailerCheck 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 MailerCheck 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.
3

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.
4

Verify the connection

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

.vscode/mcp.json

{
  "mcpServers": {
    "mailercheck-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about MailerCheck MCP in VS Code Copilot

Commit an MCP configuration file to your repository. Every developer who pulls the repo will automatically get access to the validation tools.

You need VS Code version 1.96 or higher. Agent mode must be enabled in your chat panel for the tools to function correctly.

Yes. Tell the agent to fetch your account details. It uses the API key configured in your environment to read the current credit limit.

You have to poll the API. Ask the agent to list your recent batches and look for a completed status.
