QR Rápido does not always answer

Over the last week it answered 99.4% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

QR Rápido — questions

Answers built from our own checks of this server.

Why is there no tool list for QR Rápido?

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 QR Rápido working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 758 ms. The bar chart above shows every period we have measured.

How do I connect QR Rápido?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path 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 credentials: it refuses anonymous clients.

Does QR Rápido need an API key?

Yes. Every time we knock, QR Rápido 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 QR Rápido?

It answers our handshake in 758 ms on average, which is faster than 15% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is QR Rápido open source?

We cannot say either way: written in Go, 7 260 stars on GitHub and 111 open issues, but we could not determine the licence, and without one the code is not open source by default.
