Open-Xchange MCP server
by Rheopyrin
Lets your AI read and send email, manage calendars, contacts and mail filters on your Open-Xchange account.
This is a helper for people who use Open-Xchange webmail or a similar standards-based mail service. Once it is connected, your AI assistant can look at your inbox, send and reply to messages, handle calendar events and check contacts for you. It is handy if you spend a lot of your day in email and calendars and want to ask for things in plain words instead of clicking around.
What is an MCP server? The 30-second version
On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill, here a connection to your Open-Xchange mail, calendar and contacts. You set it up once with your account details, and after that your AI can look things up or make changes there when you ask. Think of it as giving your assistant a key to your mailbox and calendar, but only for the actions you switch on.
What this MCP server does
You ask your AI something like "any new mail from Anna today?" or "book a meeting Friday at 10". The AI passes that request to this helper program, which talks to your mail server or calendar server using standard email and calendar rules. The server answers, and the helper hands the result back to the AI. The AI then writes it up for you in the chat, as a list, a summary or a short confirmation that something was sent or changed.

What it gives back to you
You get answers written in the chat, usually as short lists or summaries. For email you might see sender, subject and a snippet, or the full text of one message. For calendars you get event titles, times and locations, and for contacts you get names, emails and phone numbers. When you ask it to send or change something, it tells you what it did.
