data
data_catalog
列出本站「資料形狀 × 資料集」登錄表：有哪些 point（單值）／series（時間序列）／table（表格）／query（條件篩選＋群體聚合）資料集，各自的單位、識別碼種類、來源與深連結；query 母體另附可用欄位、運算子與可排序鍵。先呼叫本工具，即可組合出後續查詢。Catalog of datasets by shape (point/series/table/query) — call this first to compose queries.
data_point
取「一個標的 × 一個欄位 × 一個時點」的單值，如 0050 的折溢價、基金最新淨值、USD/TWD 匯率、景氣對策信號綜合分數。dataset 取自 data_catalog 的 point 清單；回應必附單位、資料日與來源。Single current value for one security and field.
data_query
對一個母體下條件篩出一組標的，並對整組計算聚合統計（count／coverage／min／max／mean／median／sum），如「費用率 0.4% 以下的被動 ETF，其費用率中位數」。where 語法為「欄位 運算子 值」以 and 連接（例 fee<=0.4 and type=passive）。回應必附母體大小 population 與欄位覆蓋率 coverage（有幾檔真的有這個欄位）。注意：績效欄位可用於 where 篩選與聚合統計，但不得作為排序鍵——排序即排名，本站不對個別商品做推薦。Filter a universe and aggregate over the matched set.
data_series
取「一個標的 × 一個欄位 × 一段時間」的時間序列，如 ETF 日收盤、基金淨值歷史。每點只有日期與值；資料缺口會以 gapNote 誠實標示、不靜默補值。Time series for one security and field.
data_table
取「一個標的的多列資料」，如 ETF 全成分股與權重、景氣對策信號 9 項構成指標、主要貨幣對一覽。回應含欄位定義（columns）與列（rows），截斷時標 truncated。Multi-row table for one security.
etf
etf_lookup
以代號查台灣上市 ETF：名稱/發行投信/追蹤指數/市價/折溢價/費用率等基本資料。Look up a Taiwan-listed ETF by code (e.g. 0050).
etf_price_history
取 ETF 每日收盤價序列（預設近 12 個月、可調 months 1-120）。Daily close history for a Taiwan ETF.
fund
fund_lookup
以代號或名稱關鍵字查台灣可銷售基金（境內投信/境外/期信）：最新淨值/淨值日/幣別/類型/總代理/今年以來報酬。Search Taiwan-distributed funds by code or name keyword.
fund_nav_history
取基金每日淨值序列（預設近 12 個月、可調 months 1-120；境內主級別最深約 10 年）。Daily NAV history for a fund.
business

market
market_sentiment
台股情緒綜合分數（本站自製中性參考、含分項）。不含美股 CNN Fear & Greed（站主裁決不透過 MCP 再散布 CNN 資料，見 /us-sentiment 的公開指標原始值）。Taiwan market sentiment (self-made neutral reference); no CNN F&G.
rates
fx_rates
主要貨幣即期匯率（多源交叉：ECB/台銀）含當日與近 1 週/1 月/3 月變化；可指定 pair（如 USD/TWD）。Spot FX rates with multi-period changes.

Tw Finance — questions

Answers built from our own checks of this server.

What can Tw Finance do?
It exposes 15 tools, read directly from the server on our last check. Among them: business_climate, data_catalog, data_point, data_query, data_series, data_table and 9 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 →
What is Tw Finance mostly used for?
Its tools cluster around data, etf and fund. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Tw Finance 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 221 ms. The bar chart above shows every period we have measured.
How do I connect Tw Finance?
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 Tw Finance need an API key?
No. Tw Finance completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Tw Finance?
It answers our handshake in 221 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
