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 OpenAI Agents SDK auto-discovers all 8 tools from MailSlurp through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries MailSlurp, another analyzes results, and a third generates reports, all orchestrated through Vinkius.
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
The MailSlurp MCP Server exposes 8 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
