Astro API — questions

Answers built from our own checks of this server.

What can Astro API do?
It exposes 8 tools, read directly from the server on our last check. Among them: astrologos.abort_job, astrologos.get_settings_link, astrologos.help, astrologos.job_result, astrologos.job_status, astrologos.run and 2 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 Astro API 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 55 ms. The bar chart above shows every period we have measured.
How do I connect Astro API?
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 Astro API need an API key?
No. Astro API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Astro API?
It answers our handshake in 55 ms on average, which is faster than 96% 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.
