README

# screenverity-mcp

MCP server for **[ScreenVerity](https://screenverity.com)** — 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

```bash
npx screenverity-mcp
```

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

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

### Claude Code

```bash
claude mcp add screenverity -- npx -y screenverity-mcp
```

### Any MCP client (stdio)

```json
{
  "mcpServers": {
    "screenverity": {
      "command": "npx",
      "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.
