Multi-Component System with A2A and MCP Server Integration

What is Multi-Component System with A2A and MCP Server Integration?

A scalable multi-component system built with modern web technologies. It integrates a React/TypeScript frontend, a Python/FastAPI backend API, a Node.js proxy server, an A2A (Agent-to-Agent) server following Google’s A2A protocol, and an MCP (Model Context Protocol) server implementing Anthropic’s protocol. Designed for developers building agent-based applications with real-time communication and modular architecture.

How to use Multi-Component System with A2A and MCP Server Integration?

Install prerequisites (Node.js 20+, Python 3.11+, npm or yarn). Run each service in its own process: API Backend (cd api; pip install -r requirements.txt; python main.py), Frontend (cd frontend; npm install; npm run dev), Proxy Server (node proxy-server.js), A2A Server (cd a2a-server; node simple-server.js), and MCP Server (cd mcp-server; pip install -r requirements.txt; python mcp_server.py). Integration tests are available in the tests directory.
