Fonteum

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

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.

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.

When provenance is present, its fields mean:

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.
