Answer: DeFi Protocol agents screen counterparties against the OFAC SDN list (19,218 names, 947 crypto wallets, 16 embargoed jurisdictions) via a single API call before every payment. A "clean": true response means proceed; "clean": false means halt. The check runs in under 100ms and the free tier covers 5 checks/day with no API key.
DeFi protocols themselves are increasingly treated as responsible for the activity their contracts facilitate - including agent-driven flows. agentmail gives protocol teams a sanctions screen they can bake into keeper agents, frontends, and router contracts so sanctioned wallets are blocked at the edge.
Regulators have sanctioned mixer contracts and named wallets; a protocol whose autonomous keepers service those addresses inherits the problem. Embedding an OFAC check in your protocol's agent layer is how you demonstrate a compliance control that scales with TVL.
Expose it as an MCP tool for your keepers or call it over HTTP from your router. Free tier for integration; paid tiers for mainnet volume.
