Sanctions

@czagents/sanctions

Sanctions screening for KYC/AML — check Czech companies and individuals against EU Financial Sanctions (FSF) and US OFAC SDN lists. Per-entity and per-statutory-member checks. Official consolidated lists, updated from source.

Install

npm install -g @czagents/sanctions

Usage with Claude Desktop

{

"mcpServers": { "sanctions": { "command": "npx", "args": ["-y", "@czagents/sanctions"], "env": { "SANCTIONS_DB": "/absolute/path/to/sanctions.db" } } } }

The local SQLite database is built by the bundled refresh CLI:

npx @czagents/sanctions-refresh

This fetches and normalizes the upstream lists into a single SQLite file. Re-run on a daily cron for fresh data.

Tools

search_person

Fuzzy-search a person across the loaded EU, OFAC and other sanctions lists. Use it for an individual name-screening step; add date of birth or nationality when you have them to reduce false positives. Do not use a low-confidence name-only match as a final sanctions decision — review the returned record and identifiers.

{"name":"Jan Novak","dob":"1974-05-12","nationality":"CZ","threshold":80,"limit":20}

search_entity

Fuzzy-search a company or organisation by name, optionally narrowed by country. Use it when you have a legal name but no reliable identifier. Do not use it for an exact Czech company-ID check; use check_ico instead.

{"name":"Acme Imports s.r.o.","country":"CZ","threshold":80,"limit":20}

check_ico

Check whether a Czech IČO, or another comparable company identifier, appears on the sanctions lists. Add name only as a fuzzy fallback when the identifier itself is not listed. Do not treat an empty result as a clean screening result if the server reports that its sanctions database is unavailable or stale.

{"ico":"12345678","name":"Acme Imports s.r.o."}

get_listing

Retrieve the complete source record for one sanctions-list entry returned by a search. Use it to inspect identifiers, aliases and source data before a human decision. Do not call it with a company IČO or person name; it accepts a listing ID such as ofac:12345.

{"id":"ofac:12345"}

list_recent_updates

Return sanctions entries added, removed or modified since a given time, optionally for one source. Use it to update an existing watchlist workflow. Do not use it to screen a particular customer portfolio: it is a global change feed, not a per-customer match.

{"since":"2026-07-01","source":"eu"}

rescreen_portfolio *(paid; available when x402 is enabled)*

Re-screen a supplied portfolio against changes in sanctions lists since its last screening and return only affected subjects. Use it for a watchlist you already maintain. Do not use it for a single person or company, or as a replacement for list_recent_updates when you need the global change feed.

{"subjects":[{"ref":"customer-42","name":"Acme Imports s.r.o.","ico":"12345678"}],"since":"2026-07-01","source":"eu"}
