Is Hacé Cuentas — Free Calculators working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1430 ms. The bar chart above shows every period we have measured.
How do I connect Hacé Cuentas — Free Calculators?
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 Hacé Cuentas — Free Calculators need an API key?
No. Hacé Cuentas — Free Calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Hacé Cuentas — Free Calculators?
It answers our handshake in 1430 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
