概览

AI 生成的概览

Epitaxy 将 FDA 药品短缺与召回数据与美国联邦药品合同关联，让助手查询存在短缺或召回风险的供应商。

可以做什么
查询数据新鲜度、活跃分段数量与最近一次运行状态，判断结果是否可信。列出当前及已解决的 FDA 药品短缺，可按状态、通用名或公司筛选。列出 FDA 药品召回与执法报告，可按分类或公司筛选。列出 USAspending 中产品服务代码 6505 的美国联邦药品合同，可按机构或公司筛选。获取供应商风险记录，将联邦合同与存在 FDA 短缺或召回的供应商关联，每行附带置信度与匹配方式。
适用场景
适合调查医药供应链风险、政府供应商的药品短缺或召回暴露，或联邦药品采购情况，并希望直接获得带明确置信度的关联结果而非原始数据。
运行要求
可作为远程 streamable HTTP 端点使用，也可通过 PyPI 包 epitaxy-mcp 以 stdio 本地运行（用 uvx 启动）。免费层无需注册或密钥；可选的 EPITAXY_API_KEY 用于付费层。EPITAXY_API_URL 可覆盖默认基础地址。需要能访问该 API 主机的网络。
安装前请注意
免费层最多返回 20 行，不含 evidence 字段与 weak 匹配，数据延迟 24 小时。跨源关联永远不会是 exact，使用前须阅读置信度（exact、probable、weak）。付费方案涉及费用（月度订阅、按次 USDC 支付或一次性批量购买）；API 密钥属于机密信息。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Epitaxy，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

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.

无需输入参数。

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.

输入参数limitstatuscompany_idgeneric_name

list_drug_recalls

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

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

输入参数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.
