Stillos Kya — questions

Answers built from our own checks of this server.

What can Stillos Kya do?
It exposes 1 tools, read directly from the server on our last check. Among them: kya_check. 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 Stillos Kya 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 235 ms. The bar chart above shows every period we have measured.
How do I connect Stillos Kya?
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 Stillos Kya need an API key?
No. Stillos Kya completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Stillos Kya?
It answers our handshake in 235 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Stillos Kya?
The npm package stillos-kya was installed 480 times in the last week. Week over week that is +193%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Stillos Kya open source?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
