Summary
This server wraps the FraudLabs Pro API to bring fraud detection directly into Claude. You get six tools split between order and user screening: validate e-commerce transactions with IP addresses and billing details, analyze registration and login events for suspicious patterns, pull historical results by transaction ID, and submit feedback (approve, reject, or blacklist) to train the detection engine. Built with FastMCP and uses stdio transport. You'll need a FraudLabs Pro API key and Python 3.10 or later. Useful if you're building commerce workflows or user onboarding processes and want real-time fraud checks without leaving your AI assistant.
