FreshProof does not always answer

Over the last week it answered 86.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

FreshProof — questions

Answers built from our own checks of this server.

What can FreshProof do?

It exposes 2 tools, read directly from the server on our last check. Among them: freshproof_info, observe_url. 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 FreshProof working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 25 of 29 checks got a reply (86.2%), average response time 405 ms. The bar chart above shows every period we have measured.

Is FreshProof still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect FreshProof?

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.

Does FreshProof need an API key?

No. FreshProof completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FreshProof?

It answers our handshake in 405 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
