Fonteum — Healthcare Provider Data MCP Server

Fonteum is a source-provenanced data layer for US healthcare providers and the organizations around them. It resolves any provider or facility by National Provider Identifier (NPI) or CMS Certification Number (CCN) across the major federal sources — the national provider registry, Medicare enrollment, quality data, and industry-payment records — and returns a joined record with the source, snapshot date, and license attached to every field. It determines whether a provider is excluded or otherwise compromised anywhere (federal OIG LEIE, federal SAM debarment, and state Medicaid exclusion lists, plus flags short of exclusion such as corporate integrity agreements and civil monetary penalties), traces the ownership chain behind a facility up to parent and private-equity entities, and exposes the published methodology behind every answer. It is for compliance, credentialing, payment-integrity, and due-diligence work that needs an audit-defensible provider fact tied back to its authoritative government source.
