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

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

One row of the answer, shortened:

{"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:

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

Local, stdio:

{ "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/exposure
https://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 An address that has been published is never withdrawn.
