Perplexity

Debug email logic inside Cursor

Stop jumping between your editor and the inbox. Use `list_sandbox_messages` to pull the latest captures straight into your chat context so you can fix bugs in real-time. Your agent parses the JSON response to identify issues. You get precise feedback on exactly where your email generation logic went sideways.

Automate test flows with Cursor

Control your email pipeline using `send_test_email` within your agent sessions. It allows you to fire off samples while you write your test suites, ensuring your hooks work as expected. This keeps your focus on the code. You build, test, and refine without ever leaving your workspace.

Review message details in Cursor

Examine headers and metadata using `get_message_details` to catch configuration errors. It provides the low-level visibility you need to ensure your SMTP settings match your expectations. When you see a discrepancy, you can fix it immediately. Your agent handles the API calls so you can stay in your flow.

Setup guide

Set up Mailtrap MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Mailtrap MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Mailtrap transactions." If the MCP tools are loaded correctly, Cursor will call the Mailtrap tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about Mailtrap MCP in Cursor

Create an `mcp.json` file in your project root. Define the server path under mcpServers, then enable Agent mode in your chat to start calling your tools.

It is essential for verifying outgoing mail triggers. By using the tools directly in the agent, you can confirm that your code generates the expected output before you commit.

Yes, use `list_mailtrap_projects` to see what you have configured. It helps you keep your environment variables synced with the right project ID in your code.

All interactions pass through the secure Mailtrap API. Your email content is never saved to your local disk, keeping your test environment clean and your data strictly within the sandbox.
