Over the last week it answered 96.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Hagglyai — questions

Answers built from our own checks of this server.

What can Hagglyai do?
It exposes 5 tools, read directly from the server on our last check. Among them: check_endpoint, compare_category, find_best, list_categories, most_popular. 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 Hagglyai 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 266 ms. The bar chart above shows every period we have measured.
How do I connect Hagglyai?
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 Hagglyai need an API key?
No. Hagglyai completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Hagglyai?
It answers our handshake in 266 ms on average, which is faster than 49% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
