German web host Mittwald is in crisis mode after an attack that came in through an MCP server. The company's own website is running in emergency mode, its blog is offline, and administration services for customers have been switched off.

That is about all that is confirmed so far. The available details do not say who is behind the attack, how much data may be affected, or when normal service is due back, so none of that is covered here.

What is an MCP server?

MCP stands for Model Context Protocol, a standard that lets AI assistants connect to outside tools and data sources. An MCP server is the piece that exposes those tools. If one is compromised, it can become a way into the systems it is wired up to, which is what makes this attack worth watching.

What does it mean for Mittwald customers?

The practical effect is that customers cannot use the administration services at the moment, because the provider has deactivated them. The emergency version of the website and the missing blog also mean less information is available from the company's usual channels.

Customers who depend on Mittwald for hosting should watch the provider's official notices for updates, since the situation was still developing at the time of writing.
