MCP server for **ScreenVerity** — U.S. exclusion, debarment and
licence screening for agents, with an Ed25519-signed receipt of exactly which list snapshots
were checked.
Screening one name through a state or federal portal usually costs an agent **~50k–200k tokens**
of browse-and-parse traffic and leaves no audit artefact. One POST /v1/screen is **~2k tokens**
of structured JSON, and it leaves evidence.
Coverage is explicit and deliberately unexaggerated — call sources and read it. This is not a
"50 states" product.

Tools
| Tool | What it does |
|------|--------------|
| screen | Screen one subject across every loaded list; returns clear / possible_match / match + a signed receipt |
| sources | Which lists are loaded, their jurisdiction, freshness, and full / partial / never_loaded coverage |
| verify_receipt | Check an Ed25519 receipt against its request/response |
**All three are free.** No API key, no account, no wallet.
Call sources before assuming any particular list is covered.
Cost
Free. There is no payment, no key and no account.
The public endpoint is rate limited. If you are limited, screen returns
{"error": "rate_limited"} — **it never fabricates a clear result.** That property is
deliberate: a screening tool that guesses is worse than no screening tool.
> 0.1.0 charged $0.25 per call via x402. That is gone. If you pinned 0.1.0, upgrade —
> it points at an endpoint that no longer exists in that form.
Using the results
- possible_match means **adjudicate**, not auto-reject.
- If complete is false, a list was unavailable — it is not a full screen.
- Always pass npi, dob, or license when you have them. Common names without identifiers are
capped at possible_match by design.
Not a consumer report
ScreenVerity is compliance-workflow tooling that retrieves and signs public exclusion-list data.
It is **not** a consumer reporting agency and its output is not a consumer report. Do not use it
to make eligibility decisions about employment, credit, insurance, or housing. Consult counsel
