About Mailsac MCP Server
Connect your Mailsac account to any AI agent to automate your email testing and inbox management. This MCP server enables your agent to reserve private email addresses, retrieve and search for messages, and inspect HTML or plain text bodies directly from natural language interfaces.
Windsurf's Cascade agent chains multiple Mailsac tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 9 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.
What you can do
- Inbox Oversight — List and manage your reserved (enhanced) addresses and custom domains
- Instant Retrieval — Fetch a list of messages received by any address in your account instantly
- Content Extraction — Retrieve sanitized HTML or raw plain text bodies to extract verification codes or links
- Inbox Maintenance — Permanently delete individual messages or clear entire inboxes via simple commands
- Infrastructure Management — Reserve new private addresses programmatically for isolated testing flows
- Global Search — Query messages across all your addresses using advanced search parameters (requires paid tier)
The Mailsac MCP Server exposes 9 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.
