Guides fraud detection: rule-based (velocity checks, amount thresholds, geo-anomalies), ML anomalies (isolation forest, autoencoders), device fingerprinting, behavioral biometrics, 3DS2, scoring pipelines, case management, chargebacks. For fraud prevention systems.

- Building or tuning velocity checks, amount anomaly rules, and geo-anomaly detection
Scans new transactions against 12-month history for fraud: duplicates within 48h, >3σ merchant anomalies, first high-dollar new merchants, unusual geo/time. Outputs severity alerts with tx ID, evidence, actions.
Automates Fraudlabs Pro operations via Composio toolkit through Rube MCP. Discovers tool schemas, manages connections, and executes fraud screening workflows.
Activate for: AML alert, transaction monitoring, suspicious activity, money laundering, structuring, smurfing, round-tripping, layering, placement, integration, typology, red flag, velocity alert, geographic anomaly, TBML, trade-based money laundering, network analysis, PEP alert. NOT for: SAR/STR drafting or filing (use aml-sar-drafting), customer onboarding or KYC documentation (use aml-cdd-edd), sanctions list screening (use sanctions-screening).
