About Mpesa Daraja MCP Server

What is Mpesa Daraja MCP Server: Secure Transactions & Scalable Growth?

Mpesa Daraja MCP Server is a Python-based solution designed to simplify integration with Safaricom's Mpesa Daraja API. Built using the FastMCP framework, it provides a secure and scalable foundation for handling financial transactions. The server focuses on two core pillars: ensuring secure token-based authentication and enabling seamless growth as transaction volumes increase. By abstracting low-level API interactions, it empowers developers to focus on business logic rather than infrastructure details.

How to use Mpesa Daraja MCP Server: Secure Transactions & Scalable Growth?

Getting started is straightforward: clone the repository, set up a virtual environment, and configure your credentials via environment variables. Once running, the server acts as a middle layer between your application and Mpesa's API. For example, a retail app could use it to generate access tokens on demand and process payments securely. The FastMCP interface ensures robust error handling, so even if network issues arise, your system remains stable and logs detailed diagnostics for troubleshooting.
