What is the 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.
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
How it works
1. Subscribe to this server
2. Enter your MailSlurp API Key (x-api-key)
3. Start managing your virtual email infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- QA Engineers — Automate the verification of user registration flows and transactional alerts via natural language
- Developers — Quickly inspect incoming test emails and manage temporary addresses directly from your IDE
- Product Teams — Monitor and audit automated communication paths and email delivery results effortlessly

Frequently asked questions
How do I find my Inbox ID?
Use the list_all_inboxes tool to see a comprehensive list of all your MailSlurp addresses along with their unique IDs.
What is the benefit of the 'wait-for' tools?
They hold the connection until an email arrives, making it easy to test asynchronous processes (like password resets) without writing complex retry loops.
Where do I find my API Key?
Log in to your MailSlurp dashboard and copy the API key from the Home or API Settings section.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call MailSlurp tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
