Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

drug
list_drug_recalls
FDA drug recalls and enforcement reports. Filters: classification (Class I, II, III), company_id, limit.
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.
data
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.
federal
list_federal_drug_contracts
US federal contracts for drugs, product service code 6505, from USAspending. Filters: agency, company_id, limit.
supplier
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.

Epitaxy — questions

Answers built from our own checks of this server.

What can Epitaxy do?
It exposes 5 tools, read directly from the server on our last check. Among them: get_data_freshness, get_supplier_exposure, list_drug_recalls, list_drug_shortages, list_federal_drug_contracts. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Epitaxy working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 242 ms. The bar chart above shows every period we have measured.
The registry lists Epitaxy as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Epitaxy?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Epitaxy need an API key?
No. Epitaxy completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How many people use Epitaxy?
The pypi package epitaxy-mcp was installed 158 times in the last week. Week over week that is +15%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Epitaxy open source?
The code is open source: it is published under the MIT licence, written in Python and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at drugs.crossgrain.xyz, which runs on its operator's own terms.
