FraudLabs Pro
The FraudLabs Pro MCP Server is a powerful integration designed to bring high-performance fraud prevention intelligence directly into your LLM-driven workflows. By utilizing the Model Context Protocol (MCP), this server allows your AI agents to validate an order or user transaction, get the validation result for an order or user transaction, and update the status for an order or user transaction using a single natural language prompt.
Key Features
-
Order Screening: Validate e-commerce orders using IP addresses, billing/shipping details, and credit card information.
-
User Screening: Analyze account-level events (registrations/logins) for suspicious patterns.
-
Transaction Management: Retrieve historical results for orders or user screenings.
-
Feedback Loop: Approve, Reject, or Blacklist transactions directly through the AI interface to improve the detection engine.
