Quicknode does not always answer

Over the last week it answered 95.8% 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 you need an API key from its owner to call it.

Quicknode — questions

Answers built from our own checks of this server.

Why is there no tool list for Quicknode?

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: 96.7% of checks in the last 24 hours got a reply.

Is Quicknode working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 92 checks got a reply (96.7%), average response time 420 ms. The bar chart above shows every period we have measured.

How do I connect Quicknode?

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 key: it refuses anonymous clients.

Does Quicknode need an API key?

Yes. Every time we knock, Quicknode 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 Quicknode?

It answers our handshake in 420 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Quicknode open source?

Yes — it is published under the MIT licence, written in JavaScript, 5 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
