vivory-mcp-verification 0.4.1

MCP server for verifiable AI work: claim/DOI verification, web archive, reproducibility hashes, C2PA/PDF/hash-chain provenance, peer-review verdicts, forecast track record, SEC EDGAR, GLEIF LEI, Wikidata, ClinicalTrials.gov, World Bank, USPTO, OpenStreetMap, DefiLlama TVL, USGS quakes, MOLIT Korean real-estate. 45 tools / 18 categories. One MCP registration so AI agents can prove what's real instead of re-inventing their verification stack.

vivory-mcp-verification

Verifiable AI work — one MCP server for every "is this real?" question.

An umbrella MCP (Model Context Protocol) server that gives AI agents a single registration for 45 verification tools across 18 categories: claim verification, DOI resolution, web archive lookup, reproducibility hash registry, media + document provenance, peer-review verdict, forecast track record, SEC EDGAR filings, GLEIF Legal Entity Identifier, OpenAlex works, Wikidata Q-numbers, ClinicalTrials.gov, World Bank macro indicators, USPTO patents, OpenStreetMap places, DefiLlama TVL, USGS earthquakes, and MOLIT Korean apartment real-transaction prices.

Built by Vivory — a verifiable AI work platform. Mission: when AI generates the world, agents need to know what's real.

What's inside (v0.4.0 — 45 tools)

Category	Tools (count)	What it answers
Claim	3	Extract / verify / archive citations from arbitrary text
DOI	4	Resolve, retraction-check, author network (Crossref + OpenAlex)
Archive	3	Wayback Machine snapshot lookup, capture, history
Repro	3	Vivory Repro Hub hash registry — match, lookup, diff
Provenance	4	C2PA, PDF metadata, hash chain, AI-watermark detection
Peer review	2	Vivory Research peer-review verdict + per-persona lookup
Forecast	2	Vivory forecast track record + agent submission
Filing	3	SEC EDGAR — ticker → CIK, recent filings, XBRL company facts
Entity	3	GLEIF — LEI lookup, name search, corporate hierarchy
Work	2	OpenAlex academic works + citation graph (sister of DOI)
Wikidata	2	Q-number entity grounding — global hallucination backbone
Trial	2	ClinicalTrials.gov v2 — NCT registry verify + search
Indicator	2	World Bank Open Data — macro indicators + time series
Patent	2	USPTO PatentsView — US patent registry (sister of KIPRIS)
Place	2	OpenStreetMap Nominatim — geo verification by ID / coords / name
TVL	2	DefiLlama — crypto protocol + chain TVL verification
Quake	2	USGS Earthquake — seismic event verification
Apt	2	MOLIT RTMS — Korean apartment real-transaction prices (매매·전월세). Aggregate stats + claim verification. Raw transaction lists + price trend live in sister vivory-mcp-korea (molit_*). Same data, different axes.

Why this exists

Modern AI agents generate citations, summaries, claims, forecasts. Most of them aren't checked. The few that are checked use whatever ad-hoc lookup the agent happens to know about — Crossref for one DOI, Wayback for one URL, a half-implemented C2PA reader for one image. Every agent re-invents the verification stack.

Vivory's bet: a single MCP server with 20+ verification tools, all wrapping api.vivory.app/api/verify/* (free anonymous tier, Pro $29/mo USDC for heavier rate limits). One install, one registration, and your agent can:

• ask whether a paragraph's citations resolve;
• check if a DOI was retracted before citing it;
• snapshot a URL to Wayback before linking it;
• match a notebook hash against the Vivory Repro Hub registry;
• inspect an image for C2PA provenance + AI watermarks;
• look up a peer-review verdict on a Vivory Research article;
• register a forecast and pick up the verdict at deadline.

Install

pip install vivory-mcp-verification

Or using uv:

uv pip install vivory-mcp-verification

The package auto-installs the vivory-mcp-verification script.

Use with Claude Code / Claude Desktop

Add to your MCP config (~/.claude/mcp.json or Claude Desktop config):

{
  "mcpServers": {
    "vivory-verification": {
      "command": "vivory-mcp-verification"
    }
  }
}

For a higher rate limit, sign up at https://api.vivory.app/dashboard/api-keys and add the key:

{
  "mcpServers": {
    "vivory-verification": {
      "command": "vivory-mcp-verification",
      "env": {
        "VIVORY_API_KEY": "vk_live_..."
      }
    }
  }
}

Use with claude mcp add (Claude Code CLI)

claude mcp add vivory-verification vivory-mcp-verification

Tier limits — Vivory API Pro

One $29/mo key unlocks BOTH MCPs. A Pro key issued for vivory-mcp-verification also unlocks vivory-mcp-korea (55 Korean public-data tools) and vice versa — the same Bearer credential is honored across the entire Vivory MCP family.

Tier	Daily quota	Notes
Anonymous	100/day/IP	No signup, polite caching
Free	500/day	Sign up at api.vivory.app/dashboard/api-keys
Pro	10,000/day	$29/mo USDC (CoolWallet · Arbitrum) or card. 31-day pass, no auto-renew, no custody. Same key unlocks vivory-mcp-korea (55 tools) = 100+ tools, one purchase.
Enterprise	100,000/day	[e-mail] (self-serve only, no SaaS sales)

Sign up at api.vivory.app/dashboard/public-api.

Heavy tools (doi_author_network depth=2, verify_claim mode=thorough, repro_artifact_diff) count as 5 calls each.

How verification verdicts work

Every endpoint returns a uniform envelope:

{
  "implementation_phase": "v0.1-real",
  "checked_at": "2026-05-06T18:00:00Z",
  "sources": ["crossref", "openalex"],
  "data": { ... },
  "note": null
}

implementation_phase is the contract:

• v0.1-real — full implementation, results trustworthy
• v0.1-partial — partial (e.g. core works, advanced sub-feature pending)
• v0.1-scaffold — envelope shape stable, backing service ships in v0.2
