Fonteum — US Healthcare Provider Data MCP Server

Data & AnalyticsLow Risk10.0LocalRemote
Free

Source-provenanced US healthcare provider data with an excluded-or-compromised-anywhere check.

About

Fonteum turns ~44 federal and state public-record sources (NPPES, CMS PECOS, OIG-LEIE exclusions, SAM.gov, NUCC, HRSA, state licensing boards) into one entity-resolved record per provider — every field carrying its source, snapshot date, and hash. Built for AI agents: clean, citable provider facts with the chain of custody attached, not guesses. ~9M providers, 44 sources, public records only (no PHI). (Point-in-time "as of any past date" history is available via the REST + FHIR API.)

Fonteum MCP Server

MCP Badge

Hosted, read-only Model Context Protocol (MCP) access to Fonteum's public-records and enforcement-integrity platform.

Fonteum organizes public records from the United States and supported global open-data registers. The service covers healthcare, federal procurement, sanctions and watchlists, federal enforcement, intellectual property, securities filings, and company registers. It returns the records available for a request together with the source and timing information available for that result.

Fonteum reports public-record facts. It does not issue clearances, risk scores, labels, or verdicts. Re-check a material match with the issuing authority before acting on it.

Connect

  • Hosted endpoint: https://fonteum.com/api/mcp
  • Transport: Streamable HTTP
  • Product documentation: fonteum.com
  • npm package: @fonteum/mcp

Claude Code

claude mcp add --transport http fonteum https://fonteum.com/api/mcp

Claude Desktop, Cursor, or Windsurf

Add the hosted server to your MCP configuration:

{
  "mcpServers": {
    "fonteum": {
      "type": "http",
      "url": "https://fonteum.com/api/mcp"
    }
  }
}

The hosted endpoint permits anonymous, rate-limited access. If Fonteum gives you a hosted transport key, send it as x-fonteum-mcp-key. Do not put credentials in a public configuration file.

Tools

These are the read-only tools currently exposed by the hosted server.

ToolAsk it when you needWhat the answer contains
fonteum_resolve_entityPublic records for one NPI, UEI, or CAGE identifier.Available provider or federal-contractor records tied to that identifier, plus source context for returned facts.
fonteum_search_recordsHealthcare provider records for a provider type and state.Matching records from the available healthcare search data. It is not a general search across every Fonteum subject area.
fonteum_check_exclusions_and_sanctionsWhether an NPI or name appears in the supported exclusion, debarment, or sanctions records.Any matching list entries, the issuing authority, and available source timing. A match needs issuer confirmation.
fonteum_get_record_as_ofAvailable federal-contractor records for a specified past date.Records available for the requested UEI or CAGE and date. Historical coverage depends on the underlying source.
fonteum_recheckA way to independently inspect Fonteum's stored verification record.A current re-check link, or details for one supplied snapshot. This supports inspection of the stored artifact; it does not prove every returned fact.
fonteum_list_sourcesThe public sources represented in Fonteum's catalog.The current catalog entries, their official publishers, source links, update notes, and reuse information when available.
fonteum_dataset_infoHow Fonteum handles sources and what the service can cover.Current method, scope notes, how to read source details, and the generated source catalog.

Inputs in plain language

  • NPI — the U.S. healthcare-provider identifier.
  • UEI — the U.S. federal-contractor identifier.
  • CAGE — a government-assigned code used to identify a contractor or supplier.
  • as_of — the date you want the contractor lookup to use, written as YYYY-MM-DD.
  • snapshot_id — an optional identifier for a specific stored Fonteum snapshot to inspect.

Reading a response

Responses may include these top-level sections. Fields can be absent or null when a source does not provide them.

SectionPlain-language meaning
dataThe answer you requested: records, matches, links, or catalog entries.
provenanceWhere an answer came from, when Fonteum handled it, and any available reuse or coverage context.
freshnessAny available indication of how recently the relevant source or assembled answer was checked.
attestationA stored verification record you can inspect independently. It is not a guarantee that every fact is true or complete.

When provenance is present, its fields mean:

FieldPlain-language meaning
_sourceThe publisher or Fonteum record set behind this answer.
_source_urlA link to the original publisher or Fonteum source page.
_dataset_idFonteum's identifier for the source collection used.
_snapshotThe stored copy or source date tied to this answer, when one is available.
_methodologyThe published method version used for the result, when supplied.
_last_checkedWhen Fonteum last checked or assembled this answer.
_confidenceA system-supplied technical value, when present; it is not a score or recommendation about a person or organization.
_data_availabilityNotes about what source context was present, unavailable, or combined.
_pipeline_versionThe processing release that produced the response.
_doiA publication identifier, if the source supplies one.
_licenseReuse terms supplied for the source, if known.
_coverage_period_startThe beginning of the time period the source says it covers, if known.
_coverage_period_endThe end of the time period the source says it covers, if known.
_slsa_provenance_urlA link to build information when one is emitted.

An empty answer or missing field means Fonteum did not return that item for this request. It does not establish that the item does not exist elsewhere.

Scope notes

Record availability, timing, and historical coverage vary by source and jurisdiction. The service only returns source context that is available for the particular result. Use fonteum_list_sources or fonteum_dataset_info when you need the current catalog rather than relying on a static inventory in documentation.
