About MailSlurp MCP Server
Connect your MailSlurp account to any AI agent to automate your email testing and asynchronous message management. This MCP server enables your agent to create virtual inboxes, send and receive emails, and handle complex automation scenarios using long-polling 'wait-for' methods directly from natural language interfaces.
The Vercel AI SDK gives every MailSlurp tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 8 tools through Vinkius and stream results progressively to React, Svelte, or Vue components. works on Edge Functions, Cloudflare Workers, and any Node.js runtime.
What you can do
- Virtual Inbox Management — Create random or custom email addresses and list all managed inboxes in your account
- Email Automation — Long-poll for the latest incoming email or wait until a specific email count is reached for testing suites
- Message Retrieval — List and inspect messages received by any virtual address, including full HTML and text bodies
- Outbound Capability — Send emails directly from any of your MailSlurp addresses programmatically
- Infrastructure Maintenance — Permanently delete individual messages or entire virtual inboxes via simple commands
- Metadata Inspection — Retrieve detailed technical headers and attachment metadata for any received email
