screenverity-mcp

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.

Install

npx screenverity-mcp

Or run the single file directly — it has no dependencies:

curl -O https://api.screenverity.com/mcp/server.js
node server.js

Claude Code

Any MCP client (stdio)

{
  "mcpServers": {

      "args": ["-y", "screenverity-mcp"]
    }
  }

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 about FCRA obligations for your use case.
