Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

twse
twse_describe_dataset
查看某個資料集的完整欄位定義,取資料前用來確認要過濾/投影哪些欄位。
twse_etf_snapshot
一次取得單一上市 ETF 的完整概況:基本資料 + 前一交易日價量 + 定期定額熱度。價量為前一交易日,不是盤中即時;要當下價格請用 twse_realtime_quote。合併三個證交所資料集並行查詢。任何一段查不到都會標成 null 並記在 caveats,不會整個失敗。
twse_get_dataset
取得證交所或期交所資料集內容,支援伺服器端過濾、欄位投影與分頁。兩邊的每個資料集都是一次回整份(可能上萬筆),務必用 code/match/fields 縮小範圍。
twse_realtime_quote
取得盤中即時報價(約 5 秒更新一次)。OpenAPI 只有前一交易日資料,要當下的價格得走基本市況報導站。ETF 與上市股票用 market="tse",上櫃用 "otc"。
twse_search_datasets
搜尋臺灣證交所與期交所 OpenAPI 有哪些資料集可用。取資料前先用這個找 dataset_id。會比對資料集代號、中文說明與欄位名稱。期交所的資料集代號一律以 taifex/ 開頭,搜期貨與選擇權可用 tag="期貨與選擇權"。
