MCP Pay Server is a standalone implementation of the Model Context Protocol (MCP) server with HTTP+SSE transport, including a basic pre-pay credit system.
The MCP Pay Server is designed to facilitate secure and efficient transactions using the Model Context Protocol (MCP) with HTTP+SSE transport. It incorporates a pre-pay credit system that leverages USDC deposits on the Base or Base Sepolia blockchain. Built with Express, TypeScript, Viem, and Zod, the server provides a robust framework for managing payments and interactions. Clients can connect to the server, fetch payment capabilities, and utilize various tools, some of which require payment. The server ensures secure transactions through cryptographic signatures and maintains an internal ledger to track client balances. This setup allows for seamless integration and usage of paid tools, enhancing the overall functionality and user experience.
