UTC Thursday of the current ISO week — questions

Answers built from our own checks of this server.

What can UTC Thursday of the current ISO week do?

It exposes 31 tools, read directly from the server on our last check. Among them: agent-ads-index, agent-tool-index, browser-url-ok, calc-eval, citation, compatibility and 25 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 UTC Thursday of the current ISO week mostly used for?

Its tools cluster around status and agent. 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 UTC Thursday of the current ISO week working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 138 ms. The bar chart above shows every period we have measured.

How do I connect UTC Thursday of the current ISO week?

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 UTC Thursday of the current ISO week need an API key?

No. UTC Thursday of the current ISO week completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is UTC Thursday of the current ISO week?

It answers our handshake in 138 ms on average, which is faster than 82% 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 UTC Thursday of the current ISO week 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.
