Star Ninja missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

inspect
inspect_observing_spot
Checks stargazing conditions at one spot over the coming nights. Returns the spot's darkness band from light-pollution data, its straight-line distance from a start point with a rough drive time, and a map link. For each night: the cloud forecast, when full darkness starts and ends (some nights have none), the moonless hours, and how much of the Moon is lit. Use it when someone asks where or when they can see stars, to check a place they name or compare several. Both the start and the spot must be given as coordinates. It does not find, rank or recommend spots, or check access or safety.

Star Ninja — questions

Answers built from our own checks of this server.

What can Star Ninja do?
It exposes 1 tools, read directly from the server on our last check. Among them: inspect_observing_spot. 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 Star Ninja working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 243 ms. The bar chart above shows every period we have measured.
How do I connect Star Ninja?
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 Star Ninja need an API key?
No. Star Ninja 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 Star Ninja?
It answers our handshake in 243 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
