Taiwan Market Open Data (Unofficial) is a remote MCP server that gives an AI agent 5 tools, among them twse_describe_dataset, twse_etf_snapshot, twse_get_dataset. It answers at https://twse-mcp.taux.io/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, succeeded.
Taiwan Stock Exchange (TWSE) open data as MCP tools: stock quotes, ETF data, 140+ public datasets.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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。 Inputs: dataset_id |
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。 Inputs: code, include_realtime |
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。 Inputs: dataset_id, code, match, fields, limit, offset |
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"。 Inputs: codes, market |
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"。 Inputs: query, tag, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://twse-mcp.taux.io/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.taux-io. Endpoint host: twse-mcp.taux.io. ARD identifier: urn:air:io.github.taux-io:mcp:twse-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
