How to Use the MailSlurp MCP in VS Code Copilot

Q: How do I deploy MailSlurp for my team in VS Code Copilot?

Commit a .vscode/mcp.json file to your repository. Every developer pulling the repo gets the MailSlurp MCP Server tools automatically when they switch Copilot Chat to Agent mode.

Q: Can VS Code Copilot read MailSlurp HTML emails?

The getemaildetails tool pulls the complete content for a specific email. Your agent can read the raw HTML, extract links, and write regex patterns based on the actual payload.

Q: How does MailSlurp handle timeouts in VS Code Copilot?

The waitforlatestemail tool uses long-polling to wait for incoming messages. This prevents the AI from hallucinating a response while the email is still in transit.

Standardize email testing across your engineering team by integrating this MailSlurp MCP Server into VS Code Copilot.

Manage test inboxes from VS Code Copilot

The `create_random_inbox` tool generates fresh email endpoints for your team's automated tests. When an engineer asks the agent to scaffold a signup flow, it provisions a real address instantly. After the test runs, `delete_specific_inbox` removes the resource from your shared account. Shared accounts often fill up with abandoned test data. By executing `list_all_inboxes`, your AI client can audit the current state of your testing infrastructure. It identifies which addresses belong to which test runs and helps maintain a clean environment.

Extract data from live emails

The `get_email_details` tool retrieves the complete content for a specific message, including headers and HTML bodies. Your agent uses this to write resilient parsers for magic links or one-time passwords. The code it generates is based on actual API responses. Verifying outbound messaging logic is just as important. The `list_inbox_emails` tool fetches the delivery record for a specific address. If an engineer needs to simulate a user reply, `send_email_from_inbox` pushes a message back to your application's webhook.

Synchronize with async delivery

The `wait_for_latest_email` tool long-polls the API to handle the unpredictable timing of SMTP delivery. Instead of writing brittle sleep functions in your test suite, your agent relies on this native waiting mechanism. If the message is already present, it returns immediately. Load testing requires verifying batch deliveries. The `wait_for_email_count` tool blocks progress until a specific number of messages hit the inbox. This guarantees your notification queues are processing at the expected volume before the test proceeds.

Setup guide

Set up MailSlurp 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 MailSlurp 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 MailSlurp tools listed. Try asking: "List my recent MailSlurp transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

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