CEV-OS Data API — questions

Answers built from our own checks of this server.

What can CEV-OS Data API do?

It exposes 13 tools, read directly from the server on our last check. Among them: get_catalysts, get_earnings_reactions, get_incident_assets, get_inform_severity, get_iss_orbit, get_macro_calendar and 7 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 CEV-OS Data API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 258 ms. The bar chart above shows every period we have measured.

How do I connect CEV-OS Data API?

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 CEV-OS Data API need an API key?

No. CEV-OS Data API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is CEV-OS Data API?

It answers our handshake in 258 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
