Overview

AI-generated overview

Remote MCP server giving assistants cited art provenance and art-market intelligence from a 282,731-node knowledge graph.

What you can do
  • Search auction and market transaction records, including lot-level prices and percentile summaries
  • Trace full custody and provenance chains with verification state and risk-window flags
  • Find era-precise comparable artworks and market-guarded valuations
  • Explore scholarly influence networks and critical reception arcs with source references
  • Federate the user's own external art-market data sources through a guarded query tool
  • Return named coverage gaps where the record is silent instead of asserting clean title
When to use it
Useful when an assistant needs to answer questions about artwork ownership history, auction prices, comparables, or Nazi-era and colonial-era restitution risk, with citations. Suited to art-market research, due diligence and collection provenance work rather than general web search.
Requirements
A remote streamable-HTTP endpoint; no local package or runtime. No key is needed during the open beta, and an optional Authorization header is accepted for higher limits. Anonymous use is capped at 5,000 calls per month per IP.
Before you install
Anonymous usage is rate-limited per IP and the provider may change beta terms. The optional Authorization header carries a secret. The federation tool accepts the user's own third-party art-market credentials, which are then used against external services. Queries and any supplied credentials go to a third-party hosted service.

Installation

In SourceWeft

  1. Open Provenio — Art Intelligence in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mildo-ai%2Fprovenio/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

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.

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. Need a higher cap? Write to [email protected].

Honesty engineering

Provenio's design contract, in one line: no model memorises art history — Provenio lets any model cite it. Every response binds to a verifiable source row; absences come back as named coverage_gaps; the evaluation harness that certifies the <1% hallucination rate is re-runnable against the live API.
