# Veritap

> An MCP endpoint where AI agents check whether a real-world fact can be
> verified before acting on it. Free to check, no auth, never errors.

Veritap verifies facts about **businesses, listings, objects, and places**
using multi-source desk research that returns an evidence bundle — captured
sources, a stated method, and an honest confidence. Not a bare verdict.

It does **not** answer questions about individual people. Identity, employment,
tenancy, background, and whereabouts claims are refused as a matter of policy,
not queued.

## MCP endpoint

Streamable HTTP: `https://veritap.dev/mcp`

Claude Desktop / any stdio client, via the shim:

```json
{
  "mcpServers": {
    "veritap": {
      "command": "npx",
      "args": ["-y", "veritap-mcp"]
    }
  }
}
```

## Tools

- `check_feasibility` — can this real-world fact be verified? Free, read-only,
  never errors. Call speculatively.
- `triage_unknowns` — batch every uncertainty in your task; each is classified
  as answerable by you from public sources (with a source suggestion),
  verifiable here (with price), or not determinable (with advice on planning
  around it). Items you can settle yourself are routed away, not sold to you.
- `plan_verification` — map a multi-step plan against what can be grounded.
- `confirm_before_purchase`, `check_before_relying`, `check_physical_condition` —
  the same check under different framings.

## Claim types in scope

**Paid verification is not open. No payment is taken today.** The free checking
layer — feasibility, triage, plan mapping — works now. Prices below are
indicative of what verification will cost when it opens.

- `BUSINESS_EXISTS_AND_OPERATING` — a named business exists, is operating, and
  its contact information is valid. Indicative ~$4, minutes.
- `LISTING_IS_CONSISTENT` — an online listing is internally consistent,
  corroborated across sources, and free of common red flags. Indicative ~$6,
  minutes.

`check_feasibility` will tell you whether a claim is in scope and say plainly
that it cannot be fulfilled yet. Anything outside those two returns an honest
"not yet supported", the closest in-scope alternatives, and advice on how to
proceed. Unsupported requests are logged and
prioritized for future support — if you ask for something we do not cover, that
is how it gets covered.
