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 53 verification tools across 22 categories: claim verification, DOI + ORCID resolution, web archive lookup, URL hash + dataset fingerprint, 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, MOLIT Korean apartment real-transaction prices, RDAP whois + DoH DNS, and EVM blockchain audit trail.

Built by Vivory — a verifiable AI work platform. Mission: in an age where everything is synthesized, verification trails become trust.

What's inside (v0.5.0 — 53 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)

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.
Identity	2	ORCID author identity — resolve iD to name + works, chain into DOI verdicts
Web	2	URL hash + dataset fingerprint — sha256 + size + ETag + structure probe
Domain	2	Domain reputation — RDAP whois (registrar + age) + Cloudflare DoH DNS (A/MX/TXT/CAA)
Chain	2	EVM blockchain audit — signed envelope over confirmed tx (Ethereum, Arbitrum, Base, Optimism, Polygon)

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 and add the key:

{
  "mcpServers": {
    "vivory-verification": {
      "command": "vivory-mcp-verification",
      "env": {

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

Real today: extract_citations · hash_chain (sha256) · verify_doi · doi_metadata · doi_retraction_check · doi_author_network (depth=1) · verify_archive · wayback_history · verify_filing · filing_recent · filing_facts · verify_lei · entity_search · entity_relationships · verify_work · search_works · verify_qid · wikidata_search · verify_trial · trial_search · verify_indicator · indicator_series · verify_patent · patent_search · verify_place · place_search · verify_protocol_tvl · verify_chain_tvl · verify_quake · recent_quakes.

Scaffold today (envelope ready, full backing in a later release): verify_claim full pipeline · archive_claim_sources batch capture · wayback_capture SPN2 dispatch · repro lookup · c2pa · pdf-provenance · watermark · peer-review verdict · forecast submit.
