Usage with Claude Desktop

"mcpServers": {
"sanctions": {

}
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.
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.
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"}
