How to Use the MailSlurp MCP in Cursor

Q: How do I add MailSlurp to Cursor?

Create an mcp.json file in your project root. Define the MCP Server under the mcpServers key, then turn on Agent mode in the chat panel.

Q: Can Cursor automatically delete MailSlurp inboxes?

Yes. The agent triggers deletespecificinbox after finishing a task. You can also instruct it to clean up all temporary addresses when you close the testing session.

Q: How does Cursor read the MailSlurp email body?

The agent calls getemaildetails to fetch the complete content. It then parses the HTML or plain text right in the chat window to help you write extraction logic.

Write integration tests in Cursor using real email addresses and live inbox data pulled straight into your code via this MCP Server.

Perplexity

Provision test addresses via the MCP Server

The `create_random_inbox` tool gives your agent a working email address while you write end-to-end tests. Cursor can drop this generated address directly into your Playwright or Cypress scripts. Once the test block is written, the AI calls `delete_specific_inbox` to clean up the backend. Managing state during test development gets messy quickly. Your AI client runs `list_all_inboxes` to see what addresses are currently active. This prevents your test suite from generating hundreds of orphaned inboxes while you debug a flaky spec.

Read and extract verification codes

The `get_email_details` tool pulls the raw HTML and text content from a specific message. When you ask Cursor to write a regex for a password reset token, it tests that pattern against the actual email payload. You know the extraction logic works before you even run the test. You also need to verify the volume of messages sent. The `list_inbox_emails` tool retrieves the history for a specific inbox. This lets your agent confirm that a bulk notification script actually sent five separate messages instead of bunching them into one.

Handle async delivery in your editor

The `wait_for_latest_email` tool solves network latency by long-polling the MailSlurp API. Cursor waits for the actual message to arrive instead of generating a mock response that hides underlying delivery issues. Testing email flows becomes much less frustrating. Complex workflows might generate multiple notifications. By calling `wait_for_email_count`, the agent pauses execution until the exact number of expected emails drop. If you need to test bounce handling, `send_email_from_inbox` lets you fire messages back into your application's ingestion pipeline.

Setup guide

Set up MailSlurp 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 MailSlurp 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 MailSlurp transactions." If the MCP tools are loaded correctly, Cursor will call the MailSlurp tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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