README
# Provenio — Art Provenance MCP **Provenance and market intelligence for AI agents.** A 282,731-node knowledge graph over 273,378 art-market transactions — the Getty Provenance Index, the Knoedler stock books (1872–1971), ERR and wartime-restitution records — served to any MCP-compliant client. **Every answer is cited. Custody gaps are named, never guessed.** Hallucination is held under 1%, verified by an externally reproducible evaluation harness rather than self-report. Where the record is silent, Provenio returns an explicit gap — it never asserts clean title. 🌐 **https://provenio.art** · Free open beta — no key, no card. ## Quick start Add the remote server to any MCP client: ``` https://provenio.art/api/mcp ``` - **Claude** (claude.ai / Desktop): Settings → Connectors → Add custom connector → paste the URL - **ChatGPT** (MCP enabled): add as a connector — `search` / `fetch` compatible - **Cursor / other clients**: streamable-http transport, no auth header needed Open beta: 5,000 queries/month per IP, all 27 tools, full corpus.

[Open an issue](https://github.com/mildo-ai/provenio/issues/new/choose). Data corrections are applied only with a citable source, and every applied correction is noted in the release log.
