Vigi-Sky does not always answer

Over the last week it answered 98.4% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Vigi-Sky — questions

Answers built from our own checks of this server.

What can Vigi-Sky do?

It exposes 20 tools, read directly from the server on our last check. Among them: aurora, capabilities, cite, doctrine, first_skies, hatch_search and 14 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 →

Is Vigi-Sky working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 91 checks got a reply (95.6%), average response time 221 ms. The bar chart above shows every period we have measured.

How do I connect Vigi-Sky?

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 Vigi-Sky need an API key?

No. Vigi-Sky completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 20 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Vigi-Sky?

It answers our handshake in 221 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
