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