Sanctions Screening MCP Server

Fetch the full record for one sanctions designation by source list + entry ID — the drill-in after sanctions_screen_name surfaces a candidate. Returns all published aliases, identifiers (passport/national-ID/tax), addresses, dates and places of birth, nationalities, sanctioning program, legal basis, and designation date. The record reflects exactly what the source published; missing fields mean the source omitted them. This is a screening aid — the designation record supports a compliance review, it is not itself a determination.

Fetch the full GLEIF Level 1 record for one LEI: legal name, other/trading names, legal and headquarters addresses, registration status, jurisdiction, registration authority and ID, and last-update date — plus any sanctions hits screened against the same legal name across all loaded watchlists. The screening cross-reference is a screening AID: a hit is a candidate to verify against the official source, and no hit is not a clearance. LEI must be a 20-character GLEIF identifier (18 alphanumerics + 2 check digits).

List the sanctions watchlists (OFAC SDN + Consolidated, EU, UK, UN) and GLEIF datasets currently loaded in the local mirror, each with its record count, source URL, license, and the mirror's readiness and as-of timestamp. Use this for provenance and freshness on any result — results are only as current as the last mirror refresh, and a not-ready mirror means screening cannot run yet. Attribution: UK data is under the Open Government Licence v3.0; all sources are cited here.

Resolve a company or organization name (with an optional ISO 3166-1 alpha-2 jurisdiction) to candidate GLEIF Legal Entity Identifiers (LEIs), ranked. This turns a free-text counterparty name into a stable global identifier that sanctions_get_entity and sanctions_trace_ownership key off. Strict mode (default) matches exact-normalized then all-tokens-present; fuzzy mode (or auto when strict is empty) adds Jaro-Winkler scoring labeled approximate with a raw 0–1 score. Returns potential matches to confirm against the GLEIF record — name resolution is a candidate ranking, not an authoritative identification.

Screen a name (person, company, vessel, aircraft) against all loaded sanctions watchlists at once — OFAC SDN + Consolidated, EU, UK, and UN — alias- and fuzzy-aware. Returns scored potential matches with the source list, sanctioning program, designation date, and the matched alias. Strict mode (default) matches exact-normalized then all-tokens-present; fuzzy mode (or auto when strict is empty) adds Jaro-Winkler and phonetic matching and labels hits approximate with a raw 0–1 similarity score. This is a screening AID for a human/compliance review, NOT a compliance determination: a hit means "review this candidate against the official source," and an empty result never means "cleared."

Trace the GLEIF Level 2 corporate-ownership graph for an LEI: direct and ultimate parents and/or children, traversed breadth-first to a bounded depth, with relationship type for each edge. Set screenNodes to also screen every entity in the graph against all loaded watchlists — beneficial-ownership screening that resolves "is anyone in this ownership chain sanctioned." Each per-node screen is a screening AID: hits are candidates to verify, and an empty result for a node is not a clearance of that node. Requires a valid 20-character LEI (use sanctions_resolve_entity to obtain one).
