Healthcare OpenData MCP (hcmcp)

醫療健保開放資料 MCP — 健保署開放資料 × 衛福部標案,對齊 Twinkle Hub query_rows,完全自主資料來源

Python 3.11+ License: MIT FastMCP

因 hub.twinkleai.tw 政策異動停用而自建的替代方案:以 FastMCP 封裝台灣醫療健保開放資料與衛福部標案,提供 Twinkle Hub 相容的 SQL 式查詢(query_rows),不依賴任何第三方聚合服務

資料來源(全部一級官方來源)

來源 資料集 取得形式
健保署資料開放平台 info.nhi.gov.tw 特約醫事機構(地區/區域醫院、診所)、保險病床比率 CSV API,每日更新、免 key
政府開放資料靜態檔(vac.gov.tw / mohw.gov.tw / mnd.gov.tw) 全民健保人數、健保平均門診就診率、國軍醫院健保不給付收費標準 data.gov.tw distribution CSV
政府電子採購網 web.pcc.gov.tw pcc-tender-mohw(衛福部標案,twinkle pcc-tender 欄位相容) 半月公開 XML

涵蓋 Twinkle Hub healthcare collection 全部 7 個資料集(data.gov.tw #39282/#39281/#9402/#25842/#176510/#142696 + pcc-tender 衛福部範圍)。

快速開始

# 安裝
git clone <repo-url> && cd healthcare-opendata-mcp
python3.11 -m venv .venv && .venv/bin/pip install -e .

# 同步資料(預設 ~/.hcmcp/hcmcp.db;決標 12 月、招標 3 月)
.venv/bin/hcmcp-sync

# 加入 Claude Code
claude mcp add hcmcp -- /path/to/.venv/bin/hcmcp

SSE 模式(團隊共用 / 容器部署):

MCP 工具

工具 說明
list_datasets 列出可查詢資料集
get_dataset(dataset_id, sample_rows) metadata + schema + 抽樣資料列
query_rows(dataset_id, where, columns, group_by, order_by, limit) SQL 式查詢與聚合(對齊 twinkle)
search_records(keyword, dataset_id) 跨資料集關鍵字搜尋
get_record(dataset_id, natural_key) 取單筆完整資料
list_sources 列出資料來源與最後抓取時間

query_rows 範例(twinkle 查詢模式直接沿用):

query_rows(
    dataset_id="pcc-tender-mohw",
    columns=["agency", "COUNT(*) AS n", "SUM(CAST(award_price AS INTEGER)) AS total"],
    where="announcement_type='決標公告' AND date >= '2025-01-01'",
    group_by=["agency"],
    order_by="total DESC",
)

SQL 安全(OWASP A03)

query_rows 接受原始 SQL 片段,以雙層防禦保護:

  1. 語法層(query_guard):僅單一 SELECT;拒絕 ; 多語句、註解、PRAGMA/ATTACH/DML/DDL;limit 硬上限 200
  2. 執行層(query_executor):mode=ro 唯讀連線 + sqlite authorizer 白名單(僅允許讀單一物化表,跨表子查詢一律拒絕)+ VM 步數上限

資料流:hcmcp-sync(ETL,可排程)→ SQLite(records 正準 + 物化查詢表同交易)→ hcmcp(唯讀 MCP server)→ Claude/Agent。抓取與查詢分離,headless browser 無必要場景(介面保留、預設停用)。

新增資料集:健保署資料集只需在 cli.pyNHI_DATASETS 登錄 rId(從 data.gov.tw 對應資料集頁取得);新資料來源則實作 SourceAdapter Protocol(discover/fetch/normalize 三方法)。

開發

.venv/bin/pip install -e ".[dev]"
