AML Transaction Screener

AML Transaction Screener is an Anti-Money Laundering compliance agent for financial institutions. It fetches the last 7 days of transactions from a read-only Postgres connection, applies a deterministic rule engine (structuring below the $10k threshold, rapid fund movement, FATF high-risk geography, OFAC sanctions/PEP counterparty detection), risk-scores each flagged transaction (0-100), and produces SAR (Suspicious Activity Report) drafts for compliance officer review. The LLM step generates a narrative summary only; all risk scores and SAR determinations are code-derived. All SAR drafts require compliance officer approval before filing — a non-negotiable guardrail. Outputs structured JSON aligned with BSA/FinCEN reporting requirements, with Slack and email alerts when configured.
