Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security66

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability79

100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
AI-judged instruction clarity (excellent).Pass
Context-footprint check failed: tool/resource definitions use about 1217 tokens (~243/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass

Capabilities100

Implements a current MCP spec version (2026-07-28).Pass

Tool Tokens

twse_describe_dataset ~72

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。

Input Output Examples

Name	Type	Req	Description
dataset_id	string	yes	來自 twse_search_datasets 的資料集代號，例如 "exchangeReport/STOCK_DAY_ALL"。

No output schema declared.

No examples provided.

twse_etf_snapshot ~165

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。

Input Output Examples

Name	Type	Req	Description
code	string	yes	ETF 代號，例如 "0056"、"0050"、"00878"。
include_realtime	boolean	–	是否附上盤中即時報價。預設 false，需要當下價格時才帶 true（多一次外呼）。

No output schema declared.

No examples provided.

twse_get_dataset ~315

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。

Input Output Examples

Name	Type	Req	Description
code	string	–	證券／基金／契約代號，例如 "0050"、"TX"。一律精確比對（不分大小寫），實際用了哪個欄位會回在 code_field_used。找不到完全相符的代號時回 0 筆，並在 code_candidates 給出拼法相近的代號——那些是候選不是答案，可能是不同商品（MXF 與 MXFFX 是不同契約），請確認後改用該代號重查，不要直接引用它們的數字。
dataset_id	string	yes	資料集代號，例如 "exchangeReport/STOCK_DAY_ALL"。
fields	array	–	只回傳這些欄位。
limit	integer	–	回傳筆數上限（硬上限 200）。
match	object	–	其他欄位的子字串過濾，例如 {"基金類型": "ETF"}。最多 20 個欄位。
offset	integer	–	分頁位移。

No output schema declared.

No examples provided.

twse_realtime_quote ~120

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"。

Input Output Examples

Name	Type	Req	Description
codes	array	yes	代號清單，例如 ["0050", "0056", "2330"]。
market	string	–	"tse"（上市）或 "otc"（上櫃）。

No output schema declared.

No examples provided.

twse_search_datasets ~180

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"。

Input Output Examples

Name	Type	Req	Description
limit	integer	–	最多回傳幾筆（預設 25）。
query	string	–	關鍵字，例如 "ETF"、"融資"、"本益比"。留空列出全部。
tag	string	–	依分類過濾，例如 "證券交易"、"公司治理"、"財務報表"。

No output schema declared.
