What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

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 92 of 92 checks got a reply (100.0%), average response time 273 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 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 sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to IBM Granite x402 Remote?
No API key is involved. IBM Granite x402 Remote answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is IBM Granite x402 Remote?
It answers our handshake in 273 ms on average, which is faster than 53% 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?
The code is open source: it is published under the Apache-2.0 licence, written in JavaScript, 264 stars on GitHub and 6 open issues. The licence covers the code in the repository, not the hosted service at three.ws, which runs on its operator's own terms.
