概覽

AI 產生的概覽

Epitaxy 將 FDA 藥品短缺與召回資料與美國聯邦藥品合約串接，讓助理查詢有短缺或召回風險的供應商。

可以做什麼
查詢資料新鮮度、上線分段數量與最近一次執行狀態，判斷結果是否可信。列出目前及已解決的 FDA 藥品短缺，可依狀態、學名或公司篩選。列出 FDA 藥品召回與執法報告，可依分類或公司篩選。列出 USAspending 中產品服務代碼 6505 的美國聯邦藥品合約，可依機關或公司篩選。取得供應商風險資料，將聯邦合約與有 FDA 短缺或召回的供應商串接，每列附帶信心值與比對方式。
適用情境
適合調查醫藥供應鏈風險、政府供應商的藥品短缺或召回曝險，或聯邦藥品採購情況，並希望直接取得附明確信心值的串接結果，而非原始資料。
執行需求
可作為遠端 streamable HTTP 端點使用，也可透過 PyPI 套件 epitaxy-mcp 以 stdio 在本機執行（以 uvx 啟動）。免費方案無需註冊或金鑰；選用的 EPITAXY_API_KEY 可解鎖付費方案。EPITAXY_API_URL 可覆寫預設基礎網址。需要能連線至該 API 主機的網路。
安裝前請注意
免費方案最多回傳 20 列，不含 evidence 欄位與 weak 比對，資料延遲 24 小時。跨來源串接永遠不會是 exact，使用前務必閱讀信心值（exact、probable、weak）。付費方案涉及費用（月訂閱、依次 USDC 付款或一次性大量購買）；API 金鑰屬機密資訊。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Epitaxy，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

README

epitaxy

mcp-name: xyz.crossgrain/epitaxy

Federal drug shortages and recalls, joined to the federal contracts that buy those drugs. One call, no signup.

What it claims: this government supplier has an active FDA shortage or recall. What it does not claim: that a specific contract supplies a specific drug. Federal contract descriptions average 47 characters and almost never name the drug, so we say so instead of pretending otherwise.

Try it now, no key

bash
curl https://drugs.crossgrain.xyz/v1/exposure?limit=5

One row of the answer, shortened:

json
{"exposure_id": "0026624dec7b6d9f", "award_id": "SPE2DP25F109W", "company_id": "a4fdd4a7530f4962", "company_name": "TEVA PHARMACEUTICALS USA, INC.", "company_key": "teva pharmaceuticals usa", "shortage_id": "022c478fb3af28c4", "confidence": "probable", "match_method": "company_name_normalized"}

MCP

Remote, nothing to install:

json
{ "mcpServers": { "epitaxy": { "url": "https://drugs.crossgrain.xyz/v1/mcp" } } }

Local, stdio:

json
{ "mcpServers": { "epitaxy": { "command": "uvx", "args": ["epitaxy-mcp"] } } }

Tools: get_data_freshness, list_drug_shortages, list_drug_recalls, list_federal_drug_contracts, get_supplier_exposure.

Read the confidence field, always

valuemeaning
exactmatch on a shared identifier, here an NDC inside FDA data
probablenormalized company name, or a drug name token in the contract text
weakanything softer, an indication only

Matching on both company and drug at once is not promoted to exact. Cross source joins are never exact, because FDA and USAspending share no identifier. Anyone claiming otherwise has a different source or is guessing.

Free tier

Works forever, no key, no signup. Returns at most 20 rows, without the evidence field, without weak matches, and with data delayed by 24 hours. Nothing is stored: no counters, no IP addresses. If a version that old does not exist yet, you get the oldest one available, so the free tier is never empty while data exists.

Addressing

These two addresses are the same segment and both work permanently:

https://drugs.crossgrain.xyz/v1/exposurehttps://drugs.crossgrain.xyz/drugs/v1/exposure

Later segments arrive as /devices/v1/..., /food/v1/... and so on. A path whose segment is reserved but not live yet answers 404 with segment_not_live, it never returns another segment's data. An address that has been published is never withdrawn.

工具

get_data_freshness

Returns when the data was last activated, how many segments are live, and the state of the last run. Call this first when you need to know whether the data is fresh.

無需輸入參數。

list_drug_shortages

Current and resolved US drug shortages as reported by the FDA. Each row carries the generic name, the reporting company and its company_id. Filters: status, generic_name, company_id, limit.

輸入參數limitstatuscompany_idgeneric_name

list_drug_recalls

FDA drug recalls and enforcement reports. Filters: classification (Class I, II, III), company_id, limit.

輸入參數limitcompany_idclassification

list_federal_drug_contracts

US federal contracts for drugs, product service code 6505, from USAspending. Filters: agency, company_id, limit.

輸入參數limitagencycompany_id

get_supplier_exposure

The join: a federal contract whose supplier has an FDA shortage or recall. Every row carries company_name, confidence (exact, probable or weak) and match_method. A cross source join is NEVER exact, because FDA and USAspending share no identifier. The claim is: this government supplier has an active FDA shortage or recall. It does NOT claim that this contract delivers that drug. Without a key you get exact and probable matches only, at most 20 rows, without the evidence field.
