IBM Granite x402 Remote — questions

Answers built from our own checks of this server.

Why is there no tool list for IBM Granite x402 Remote?
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 IBM Granite x402 Remote 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 274 ms. The bar chart above shows every period we have measured.
How do I connect IBM Granite x402 Remote?
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 IBM Granite x402 Remote need an API key?
Yes. Every time we knock, IBM Granite x402 Remote 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 IBM Granite x402 Remote?
It answers our handshake in 274 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is IBM Granite x402 Remote open source?
Yes — it is published under the NOASSERTION licence, written in JavaScript, 92 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.
