ChronoKey — questions

Answers built from our own checks of this server.

What can ChronoKey do?
It exposes 16 tools, read directly from the server on our last check. Among them: domain.intel, extract.and.fetch, extract.and.summarize, extract.confirm, extract.verified, gas.price and 10 more. 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 →
What is ChronoKey mostly used for?
Its tools cluster around extract, memory and text. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is ChronoKey working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 171 ms. The bar chart above shows every period we have measured.
How do I connect ChronoKey?
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 ChronoKey need an API key?
No. ChronoKey completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is ChronoKey?
It answers our handshake in 171 ms on average, which is faster than 75% 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 ChronoKey open source?
We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
