The disclosure registry for the EU AI Act

Providers disclose once. Deployers verify fast.

AI providers publish Article 13 and Annex IV-aligned records once into a neutral registry. Deployer organisations retrieve them instantly by API — with versioning, identity, and audit-grade evidence built in.

↳ Providers — one structured record replaces a stack of repeat questionnaires

↳ Deployers — real-time, machine-readable disclosures replace stale PDFs

↳ Auditors — versioned records with full change history for compliance evidence

Aligned with

EU AI Act Article 13 Annex IV

MCX registry showing 1,284 records across 168 providers — each row a model with provider, Annex III use case, risk class, schema coverage, version, verification status, and deployer count

The problem

Two sides of the same broken process.

Deployer procurement teams wait for stale PDFs. Provider compliance teams answer the same questionnaire many times. Neither side has machine-readable evidence. Under the EU AI Act, that's no longer just inefficient — it's a legal liability.

For AI providers

Drowning in questionnaires.

AI providers with enterprise pipelines answer the same questions dozens of times a year. Every deployer sends a different format. Every deal repeats the manual effort. There is no publish once — until now.

Weeks of effort lost per provider, per year, to duplicate disclosure work

For deployer organisations

On the hook for every third-party AI model.

Deployer procurement teams assess a growing roster of AI providers a year: send spreadsheet, wait two weeks, receive a stale PDF, repeat at every renewal. "The provider said it was compliant" is not an audit trail under the EU AI Act.

Not machine-readable today's provider disclosures arrive as PDFs and spreadsheets
