About Mailosaur MCP Server
Connect your Mailosaur account to any AI agent to automate your email and SMS testing workflows. This MCP server enables your agent to manage virtual servers (inboxes), retrieve and search for messages, and extract content for validation directly from natural language interfaces.
Windsurf's Cascade agent chains multiple Mailosaur tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 8 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.
What you can do
- Virtual Inbox Oversight — List and manage all virtual servers and retrieve their unique routing domains
- Message Retrieval — List all email and SMS messages received by a specific server instantly
- Advanced Search — Find specific messages by sender, recipient, subject, or body content using detailed criteria
- Content Inspection — Retrieve the full HTML and text content of any message for automated validation
- Inbox Maintenance — Clear entire server inboxes or delete specific messages via simple commands
- Dynamic Infrastructure — Create and configure new virtual servers programmatically for testing isolation
The Mailosaur MCP Server exposes 8 tools through the Vinkius. Connect it to Windsurf in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
