Overview

What is Chatbot MCP?

Chatbot MCP is an intelligent chatbot that uses the Model Context Protocol (MCP) to process natural language requests and perform operations such as CPF validation and recharge (add/subtract balance). It is built with TypeScript, Express.js, and OpenAI GPT-4, and is intended for developers who need a conversational interface for account management tasks.

How to use Chatbot MCP?

Install Node.js 18+, clone the repository, run npm install, and create a .env file with your OPENAI_API_KEY. Start the server with npx ts-node server.ts and the client with npx ts-node index.ts in a separate terminal. Then send natural language commands like “Realizar uma recarga de R$50 para o CPF 123.456.789-09” to perform recharge or debit operations.
