EdgeOne Pages: MCP Client and Server Implementation with Functions

Project Overview

This project showcases an intelligent chat application built with EdgeOne Pages Functions technology. It interacts with backend functions through a web interface, implementing a complete Model Context Protocol (MCP) workflow.

The system architecture consists of the following core components:

• MCP Streamable HTTP Server (functions/mcp-server/index.ts)
• MCP Client (functions/mcp-client/index.ts)
• Backend API (functions/v1/chat/completions/index.ts) as the MCP HOST, responsible for coordinating the entire MCP workflow

Through this architecture, users can access powerful MCP tool capabilities in the browser, enabling intelligent interactions such as "generating online webpages with a single prompt."

Core Features

• Interactive Chat Interface: Modern, responsive web interface built with Next.js and React
• High-Performance Edge Functions: Critical business logic deployed on highly scalable EdgeOne Pages Functions
• Complete MCP Implementation: Model Context Protocol implementation based on the latest specifications, providing powerful context management and request routing capabilities
• OpenAI Format Compatible: Backend API fully supports OpenAI-formatted request and response handling

Streamable HTTP MCP Server

Configure remote MCP services in applications that support Streamable HTTP MCP Server.
