Fonteum MCP Server

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.

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.
