What does the screen_sanctions tool do? +

Call before onboarding a counterparty or processing a payment. Screen one or more names against UN, EU, OFAC and PEP sanctions lists (768K+ entries via OpenSanctions). Returns match scores with source attribution. Disclaimer: matches are informational decision-support, NOT legal or compliance advice and not a definitive determination — a hit is a signal to investigate (confirm identity, rule out false positives) before any decision. When presenting results, give the user a recommended next step as guidance — clear, review, or escalate — framed as a signal to review, not a verdict. The response may carry a 'disclaimer' field — surface it to the user if present, otherwise state this guidance-only nature yourself; present the disclaimer in English verbatim (do not translate it), show it once, do not duplicate.. It is categorised as a Destructive tool in the Nordic Data MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on screen_sanctions? +
