huangli
huangli
Chinese almanac for a date: 宜 (auspicious activities), 忌 (avoid), 冲煞, 彭祖百忌. date omitted = today.

Chinese lunar calendar for any date: 农历、干支纪年、生肖、节气、节日、星座。date omitted = today.

what
what_can_you_do
Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-to-run example calls — instead of reading the whole catalogue and guessing. Also returns multi-step recipes when a task needs several tools chained (invoices to a ledger, a bank statement reconciled, a messy CSV turned into a deliverable). Deterministic and free: it calls no model, costs nothing, and never runs out of quota. Call this FIRST when you are not sure what this server offers.

Netcafe China — questions

Answers built from our own checks of this server.

What can Netcafe China do?
It exposes 11 tools, read directly from the server on our last check. Among them: bazi_chart, china_reachability, cn_holiday, huangli, id_card_check, lunar_calendar and 5 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 Netcafe China working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 64 of 92 checks got a reply (69.6%), average response time 957 ms. The bar chart above shows every period we have measured.
How do I connect Netcafe China?
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 Netcafe China need an API key?
No. Netcafe China completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Netcafe China?
It answers our handshake in 957 ms on average, which is faster than 6% 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.
Is Netcafe China open source?
We cannot say either way: written in JavaScript, 1 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
