Provenio · Archived

The live service has been retired.

Provenio was an independent, non-commercial research project: a provenance knowledge graph of 282,731 nodes (built on CIDOC-CRM and PROV-O) served over the Model Context Protocol, so an AI could answer questions about an artwork's ownership history.

Its defining principle was restraint — where the records showed no custody link, the tool returned that gap as data rather than inventing a plausible answer. Silence over a confident guess.

As of August 2026, the hosted database and the provenio.art/api/mcp endpoint have been shut down. What remains open:

• The open-source MCP server code: github.com/mildo-ai/provenio
• Questions or archival requests: ceo@provenio.art

Thank you to everyone who connected, queried, and kicked the tires.
