Nothing serious here today

Today is the operative word: we check Bankday every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Bankday — questions

Answers built from our own checks of this server.

What can Bankday do?

It exposes 8 tools, read directly from the server on our last check. Among them: ach_settlement_date, add_business_days, count_business_days, fx_spot_date, is_business_day, list_holidays 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 Bankday working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 86 of 86 checks got a reply (100.0%), average response time 80 ms. The bar chart above shows every period we have measured.

How do I connect Bankday?

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. You will need your own key: it refuses anonymous clients.

Does Bankday need an API key?

Yes. Every time we knock, Bankday answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Bankday?

It answers our handshake in 80 ms on average, which is faster than 89% 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.
