Example MCP Server Built on Next.js: Universal Adapter for AI Applications

Overview: What is Example MCP Server?

The Example MCP Server built on Next.js is an advanced infrastructure that serves as an essential component in integrating AI applications with specific data sources and tools through a standardized protocol, called the Model Context Protocol (MCP). This protocol functions similarly to USB-C, enabling AI applications like Claude Desktop, Continue, Cursor, and more to connect seamlessly to diverse data contexts. The server is designed for developers looking to enhance their AI workflows by providing a flexible and efficient environment that supports various tools such as databases, APIs, and custom scripts.

🔧 Core Features & MCP Capabilities

The Example MCP Server boasts several key features that make it indispensable for integrating complex AI applications:

• MCP Protocol Alignment: Integrates seamlessly with MCP clients like Claude Desktop, Continue, and Cursor to enable a unified approach in processing data and tools.
• Real-Time Data Processing: Supports real-time communication via Server-Sent Events (SSE) and Fluid Compute on Vercel for efficient execution of tasks.
• Customizable Resources & Tools: Users can modify app/mcp.ts according to the MCP TypeScript SDK documentation, ensuring that their AI application can access necessary tools and resources.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Example MCP Server is meticulously designed to leverage the power of MCP for seamless data processing and tool integration. The protocol flow ensures reliable communication between AI applications, servers, and external resources:

This diagram illustrates how an AI application connects to a specific MCP client, which then interacts with the server implementing the MCP protocol. The server then retrieves and processes data or tools as required.

🚀 Getting Started with Installation

To get started with installing the Example MCP Server on Next.js:

1. Set Up MCP Context: Ensure that you have Redis installed via process.env.REDIS_URL.
2. Enable Fluid Compute: Enable Fluid Compute for efficient execution, especially if using a Vercel Pro or Enterprise account.
3. Deploy Template: Deploy the Example Next.js MCP template provided by Vercel.

💡 Key Use Cases in AI Workflows

Use Case 1: Real-Time Data Analysis for Financial Applications

AI applications like Continue and Cursor leverage real-time data analysis to provide financial insights:

• Scenario: A user wants to analyze stock trends using historical data. The Example MCP Server allows the AI application to query a Redis database connected via an MCP server, process the data in real time using SSE for Fluid Compute, and offer timely updates on market conditions.

Use Case 2: Personalized User Recommendations

The Example MCP Server plays a crucial role in delivering personalized recommendations based on user behavior:

• Scenario: An e-commerce AI application uses the Example MCP Server to fetch product recommendations from various data sources. Tools like Product Lookup API and Customer Behavior Analysis Tool are integrated via MCP, allowing for dynamic and context-aware recommendation engines.

🔌 Integration with MCP Clients

The Example MCP Server ensures compatibility with a range of MCP clients:

• Claude Desktop: Full support including access to tools, resources, and advanced prompts.
• Continue: Supports all core features but may have limitations in custom script integration due to API constraints.
• Cursor: Currently supports only tool integration, lacking support for additional resources.
