FraudLabs Pro MCP Server

An MCP-compliant server that integrates the FraudLabs Pro fraud detection system into AI assistants like Claude Desktop. This server enables real-time screening of order transactions and user-related events (like logins or registrations) to identify and prevent fraudulent activities.

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.

Prerequisites

• Python 3.10+ installed.
• FraudLabs Pro API Key: You can obtain a free or paid API key at FraudLabs Pro.

Development & Logging

The server uses FastMCP and sends logs through the MCP context. You can view logs in the Claude Desktop "Developer Console" to inspect outgoing payloads and API responses for debugging.

Common Error: If you receive "An API key is needed," ensure the FRAUDLABSPRO_API_KEY environment variable is correctly set in your configuration file and that you have restarted the MCP client.
