MCP Payment System

Example Use Cases

• 1

  Process and query payment data (summaries, transaction details, and add payments) through MCP-exposed tools.

• 2

  Run automated fraud checks and generate risk reports using built-in fraud detection utilities.

• 3

  Integrate payment workflows with LLMs or to interactively develop and test payment flows using the MCP Inspector locally.

Description

This repository implements a payment-processing MCP server with two modes: a basic implementation for learning and testing and an enhanced, production-ready implementation with multi-currency support, advanced fraud detection, and full audit logging. It is designed for interactive development via the MCP Inspector and for integration with AI models (examples include Claude) through a configured MCP server. The project includes structured logging, input validation and security measures, sample tools (payment summary, payment details, fraud checks), and example configuration for running locally.
