Nothing serious here today

Today is the operative word: we check OpenWall every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This endpoint answered with an authorization challenge. The server is running, but you need an API key from its owner to call it.

OpenWall — questions

Answers built from our own checks of this server.

Why is there no tool list for OpenWall?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is OpenWall 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 265 ms. The bar chart above shows every period we have measured.

How do I connect OpenWall?

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 will need your own key: it refuses anonymous clients.

Does OpenWall need an API key?

Yes. Every time we knock, OpenWall answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is OpenWall?

It answers our handshake in 265 ms on average, which is faster than 54% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
