Opensanctions Mcp

scka-de/opensanctions-mcp

Connects Claude to the OpenSanctions API for screening individuals and companies against 320+ sanctions lists from OFAC, EU, UN, and UK HMT, plus PEP databases. You get six tools: search by name or keyword, match entities using structured properties like birth date and nationality, fetch full entity details with relationships, list available datasets, get dataset metadata, and run full compliance investigations that combine matching with relationship mapping. Works with the hosted OpenSanctions API (free key required) or your own self-hosted yente instance. Useful when you need to check sanctions exposure during due diligence, onboarding workflows, or compliance investigations without leaving your AI chat.
