matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun) — questions

Answers built from our own checks of this server.

Why is there no tool list for matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun)?
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 matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun) 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 543 ms. The bar chart above shows every period we have measured.
How do I connect matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun)?
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 credentials: it refuses anonymous clients.
Does matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun) need an API key?
Yes. Every time we knock, matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun) 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 matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun)?
It answers our handshake in 543 ms on average, which is faster than 22% 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.
Is matchwire.win — Mapped Prediction Markets (Kalshi, Polymarket, Predict.fun) open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.matchwire.win, which runs on its operator's own terms.
