✦ MCP server · works with Claude, Cursor, VS Code & any MCP client

Send a calendar invite to a cell number —
and get their RSVP and email back.

maeil runs as an MCP server. Ask your assistant to send a calendar invite to a cell number — the recipient gets it as a text, and when they accept, their real email comes straight back into the conversation. No app for them to install, no copy-paste, no manual contact entry.

With your AI assistant

Three steps, all inside the chat

1

Ask your assistant

"Invite +1 555 010 0000 to coffee Thursday at 10." Your MCP-connected assistant calls maeil's send_calendar_invite tool — no leaving the conversation.

2

They get a text

The recipient receives a real calendar invite by SMS over Twilio's A2P 10DLC network. They accept or decline with a tap. They choose to share their email.

3

The email comes back

On accept, the revealed email returns to your assistant via get_invite_status — ready to save to a contact, drop into your CRM, or add as a calendar guest.

Connect in a minute

Point any MCP client at maeil

Mint a key in your dashboard (Power and up), then add maeil to your client's MCP config. Any client that can send an Authorization header works.

{ "mcpServers": { "maeil": { "url": "https://mcp.maeil.cc/mcp", "headers": { "Authorization": "Bearer mk_live_…" } } } }

Two tools: send_calendar_invite and get_invite_status. Full setup guides for Claude Desktop, Claude web, ChatGPT, Cursor and VS Code are in the docs.

FAQ

Working with your assistant

Which AI assistants can use maeil?

Claude (Desktop & web), Cursor, and VS Code today — through the bundled local connector or by attaching an Authorization: Bearer header to the remote endpoint at https://mcp.maeil.cc/mcp. Any MCP client that can send a header works.

Do I need a paid plan to use the MCP server?

Yes — MCP and personal API access are included on the Power plan ($49/year) and up. The Free and Standard plans don't include API or MCP access.

Does maeil work with ChatGPT?

ChatGPT's web connector may require an OAuth 2.1 flow and can refuse a static Bearer key, which maeil v1 doesn't support yet. Until OAuth ships, connect ChatGPT through the local connector.

What does the person I invite need?

Nothing to install. They get a normal text with a calendar invite and accept with one tap — their email is shared back to you only if they accept.
