H-Index — questions

Answers built from our own checks of this server.

What can H-Index do?
It exposes 3 tools, read directly from the server on our last check. Among them: get_listing, list_categories, search_registry. 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 H-Index 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 326 ms. The bar chart above shows every period we have measured.
How do I connect H-Index?
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 H-Index need an API key?
No. H-Index 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 H-Index?
It answers our handshake in 326 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
