Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Fonteum for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Read-only MCP access to Fonteum's US public-record data, letting an assistant look up healthcare provider, contractor, exclusion and sanctions records with…

What you can do: Resolve public records for an NPI, UEI or CAGE identifier
Search healthcare provider records by provider type and state
Check exclusion, debarment and sanctions lists for an NPI or name
Look up federal-contractor records as of a past date and re-inspect stored verification snapshots
List the public sources in Fonteum's catalog and read its methodology and scope notes
When to use it: Useful when an assistant needs sourced US healthcare provider or federal contractor facts, or a check against exclusion and sanctions lists, with provenance and freshness details attached. Also handy for inspecting which public sources back an answer before relying on it.
Requirements: Runs as a local npm package via npx, or connects to Fonteum's hosted endpoint. An API key can be supplied through FONTEUM_API_KEY; without one it falls back to a free read-only demo key limited to 100 requests per hour per IP. FONTEUM_API_BASE can point at a self-hosted or staging API. Network access is required.

Before you install

Results are public-record facts, not clearances, risk scores or verdicts, and a match should be confirmed with the issuing authority before acting. Empty answers or missing fields do not prove an item does not exist. Keep any API key out of public configuration files. Desktop-only; no web execution.

Installation

In SourceWeft

Open Fonteum — Healthcare Provider Data in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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 Desktop, Cursor, or Windsurf

Add the hosted server to your MCP configuration:

json

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

{  "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.

Tool	Ask it when you need	What the answer contains
`fonteum_resolve_entity`	Public 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_records`	Healthcare 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_sanctions`	Whether 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_of`	Available 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_recheck`	A 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_sources`	The 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_info`	How 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.

Section	Plain-language meaning
`data`	The answer you requested: records, matches, links, or catalog entries.
`provenance`	Where an answer came from, when Fonteum handled it, and any available reuse or coverage context.
`freshness`	Any available indication of how recently the relevant source or assembled answer was checked.
`attestation`	A 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:

Field	Plain-language meaning
`_source`	The publisher or Fonteum record set behind this answer.
`_source_url`	A link to the original publisher or Fonteum source page.
`_dataset_id`	Fonteum's identifier for the source collection used.
`_snapshot`	The stored copy or source date tied to this answer, when one is available.
`_methodology`	The published method version used for the result, when supplied.
`_last_checked`	When Fonteum last checked or assembled this answer.
`_confidence`	A system-supplied technical value, when present; it is not a score or recommendation about a person or organization.
`_data_availability`	Notes about what source context was present, unavailable, or combined.
`_pipeline_version`	The processing release that produced the response.
`_doi`	A publication identifier, if the source supplies one.
`_license`	Reuse terms supplied for the source, if known.
`_coverage_period_start`	The beginning of the time period the source says it covers, if known.
`_coverage_period_end`	The end of the time period the source says it covers, if known.
`_slsa_provenance_url`	A 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.
