Nothing serious here today

Today is the operative word: we check ColdRead every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

coldread
coldread_check
Before paying an x402 seller: one signed, independent report combining a 402-challenge lint, signed-offer and signer-authorization checks, an ERC-8004 identity lookup and a labelled Base USDC payer summary over the last ~28 h. Read-only; never pays. Free.
coldread_get_report
Fetch a stored signed report by its sha256 digest (reports are kept 90 days).
coldread_verify_report
Check that a ColdRead report envelope is unmodified (JCS + sha256) and signed by a published ColdRead key. Pass the whole envelope {report, digest, signature}.

ColdRead — questions

Answers built from our own checks of this server.

What can ColdRead do?
It exposes 3 tools, read directly from the server on our last check. Among them: coldread_check, coldread_get_report, coldread_verify_report. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is ColdRead 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 100 ms. The bar chart above shows every period we have measured.
How do I connect ColdRead?
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.
Does ColdRead need an API key?
No. ColdRead completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is ColdRead?
It answers our handshake in 100 ms on average, which is faster than 92% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is ColdRead open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at coldread.something-agent.workers.dev, which runs on its operator's own terms.
