This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

invite
get_invite_status

send
send_calendar_invite
Invite a person to a calendar event using only their phone number. They receive the invite as a text message; if they accept, their real email address is returned to the organizer (retrieve it with get_invite_status, or have it POSTed to your callback_url). US phone numbers only (including Puerto Rico and other US territories); Canadian and other international numbers are not supported and will be refused. You must attest that you have the recipient's consent to contact them about this event.

Maeil — questions

Answers built from our own checks of this server.

What can Maeil do?
It exposes 2 tools, read directly from the server on our last check. Among them: get_invite_status, send_calendar_invite. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Maeil working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 137 ms. The bar chart above shows every period we have measured.
How do I connect Maeil?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Maeil?
No API key is involved. Maeil answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Maeil?
It answers our handshake in 137 ms on average, which is faster than 85% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
