Ethereum Toolkit does not always answer

Over the last week it answered 49.8% 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.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Ethereum Toolkit — questions

Answers built from our own checks of this server.

Why is there no tool list for Ethereum Toolkit?

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: 50.0% of checks in the last 24 hours got a reply.

Is Ethereum Toolkit working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 184 checks got a reply (50.0%), average response time 316 ms. The bar chart above shows every period we have measured.

How do I connect Ethereum Toolkit?

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 Ethereum Toolkit need an API key?

Yes. Every time we knock, Ethereum Toolkit 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 Ethereum Toolkit?

It answers our handshake in 316 ms on average, which is faster than 45% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Ethereum Toolkit open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
