This endpoint answered with an authorization challenge — the server is running, but you need an API key or OAuth to use it.

GrapeCity SpreadJS — questions

Answers built from our own checks of this server.

Why is there no tool list for GrapeCity SpreadJS?

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 GrapeCity SpreadJS 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 989 ms. The bar chart above shows every period we have measured.

How do I connect GrapeCity SpreadJS?

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 or an OAuth login: it refuses anonymous clients.

Does GrapeCity SpreadJS need an API key?

Yes. Every time we knock, GrapeCity SpreadJS 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 GrapeCity SpreadJS?

It answers our handshake in 989 ms on average, which is faster than 6% 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.
