These are the live hosted tools and the matching future stdio package contract. They return public-record context only; no tool mutates a record. Use only the source and as-of values the response supplies, preserve null values, and read the listed limitations before reuse. Every registration carries readOnlyHint: true.
fonteum_lookup_npiLook up an NPI
Look up a US healthcare provider by 10-digit NPI in CMS NPPES and return the available provider record plus exclusion and program-integrity context. Returns dated source context; source_file and snapshot_digest are nullable when no single retained snapshot represents the response. Use for NPI lookup, provider identity, taxonomy, practice-location, or provider due-diligence questions.
fonteum_lookup_contractorLook up a contractor
Look up a US federal contractor by UEI or CAGE in available SAM.gov, USASpending, FAPIIS, and FAR 4.18 records. Returns dated source context; source_file and snapshot_digest are nullable when no single retained snapshot represents the response. Use for contractor identity, registration, award, responsibility, or ownership due diligence.
fonteum_search_providersSearch providers
Search US healthcare providers in loaded CMS NPPES specialty caches by vertical and state, with optional county context. Returns dated source context and up to 100 records; source_file and snapshot_digest may be null. Use for provider discovery by specialty and geography.
fonteum_check_exclusionCheck an exclusion
Check whether a US healthcare provider by NPI appears in available exclusion or integrity sources: OIG LEIE, SAM.gov exclusions, available state Medicaid lists, OIG Corporate Integrity Agreements, and CMS Civil Money Penalties. Returns dated source context and fail-closed coverage; source_file and snapshot_digest may be null for the multi-source result. Use for exclusion screening, provider or vendor due diligence, or any ‘is this NPI excluded?’ question.
fonteum_search_sanctionsSearch sanctions
Search a person or organization name across available sanctions and watchlist data from OFAC, the EU, the UK, and the UN, plus named exclusion sources held by Fonteum. Returns dated matches with source context; source_file and snapshot_digest may be null for the multi-source result. Use for sanctions screening, entity due diligence, or any ‘is this entity sanctioned?’ question.
fonteum_lookup_contractor_historyRead contractor history
Look up a US federal contractor record as of a requested date using UEI or CAGE. Retained history is currently limited to USASpending award rows; other fields may be current, absent, or nullable. Returns dated source context. Use for historical award research or contractor change questions.
fonteum_recheck_snapshotRe-check a snapshot
Recheck a Fonteum snapshot by snapshot id and return its as_of_date, snapshot_digest, public verifiable_url, and source_file only when explicit retained-artifact metadata is available. Without an id, returns chain status without treating the chain head as a snapshot digest. Use for snapshot integrity checks, citation support, or reproducing a retained source file.
fonteum_list_sourcesList sources
List Fonteum’s public-record source catalog with available authority, vertical, cadence, official URL, and separately dated platform coverage. Catalog presence does not prove loaded, fresh, or complete coverage. Use for source discovery, coverage questions, or choosing a dataset before a lookup.
fonteum_get_dataset_infoRead dataset metadata
Get Fonteum API and MCP methodology, provenance-field definitions, generated source catalog, and separately dated platform coverage. Field population varies by source and response. Use for interpreting Fonteum outputs, citation fields, dataset limitations, or integration planning.
