Every calendar needs an email to invite someone — but you often just have a phone number. maeil fixes it: add 5551234567@maeil.cc as a guest in Google/Apple/Outlook, they get a text, tap accept, and their RSVP + real email come back. It's also a live MCP server + REST API — point Claude, ChatGPT, Cursor, or VS Code at mcp.maeil.cc and your agent books a meeting from a bare number, the one thing every AI scheduler can't do. Free to start; MCP on Power. PRODUCTHUNT = 50% off year one.
