Example Next.js MCP Server: Universal Adaptation for AI Applications

Overview: What is Example Next.js MCP Server?

The Example Next.js MCP Server leverages the Vercel MCP Adapter to facilitate seamless integration between AI applications and Model Context Protocol (MCP). This server allows developers to connect various AI tools, prompts, and resources through a standardized protocol, enabling broader compatibility with a range of MCP clients. The purpose is to enhance the flexibility and extensibility of Next.js projects by embedding these capabilities directly within the application framework.

🔧 Core Features & MCP Capabilities

The core strength of Example Next.js lies in its ability to support multiple AI applications via MCP. It implements real-time communication using Server-Sent Events (SSE) and other advanced features provided by Vercel Functions, such as Fluid compute for efficient execution. The adapter is designed to be compatible with a wide range of MCP clients, ensuring that this server can serve as the backbone for diverse AI workflows.

Protocol Implementation

The MCP protocol flow can be visualized using a Mermaid diagram as follows:

graph TD
    A[AI Application] -->|MCP Client| B[MCP Protocol]
    B --> C[MCP Server]
    C --> D[Data Source/Tool]
    style A fill:#e1f5fe
    style C fill:#f3e5f5
    style D fill:#e8f5e8

This diagram illustrates the interaction where an AI application sends requests through an MCP client, which then uses the MCP protocol to communicate with the server. The server processes these interactions and retrieves data from associated tools and resources.

⚙️ MCP Architecture & Protocol Implementation

The architecture of Example Next.js is built around the Vercel MCP Adapter, which dynamically inserts the necessary logic into specific routes within a Next.js application. This adapter works seamlessly with the TypeScript SDK provided by Model Context Protocol (MCP) to handle requests and responses efficiently.

Server Integration

To integrate the MCP server in your project, follow these steps:

Install the @vercel/mcp-adapter package.
Update app/[transport]/route.ts following the MCP TypeScript SDK documentation.
Ensure Fluid compute is enabled in Vercel settings for resource-efficient execution, and adjust maxDuration appropriately.

🚀 Getting Started with Installation

Begin by deploying the Next.js MCP template using Vercel:

npm create vercel@latest --example https://github.com/vercel/next-templates/tree/master/mcp-template next-<appname>
cd next-<appname>

For integration, update your app/route.ts file with the required MCP server logic:

import { mcpRoute } from '@vercel/mcp-adapter';
import { server } from './[mcp-server-id]';

export default mcpRoute({
  path: '/invoke',
  method: 'POST',
  handler: async ({ command, args, env }) => {
    try {
      const response = await server(command as string, args);
      return { body: JSON.stringify(response) };
    } catch (error) {
      console.error('MCP Server Error:', error);
      throw new Error(JSON.stringify({ code: 500, message: 'Internal Server Error' }));
    }
  },
});

💡 Key Use Cases in AI Workflows

Example Next.js can integrate seamlessly into various AI workflows. Here are two practical scenarios:

Scenario 1: Content Generation with AI Tools

Imagine a scenario where an AI application needs to generate content based on user inputs and external data sources. The server can process requests by invoking appropriate tools and returning enriched responses.

Scenario 2: Data Driven Automation

In another use case, the server could be used in automated data processing pipelines where real-time interactions with other services are required. MCP ensures that these interactions remain seamless and efficient.

🔌 Integration with MCP Clients

This server supports a variety of MCP clients including but not limited to:

Claude Desktop: Fully supported with all features enabled.
Continue: Supports data resources and tool access.
Cursor: Limited support for tools without prompt functionality.

You can test the server integration using a sample client script:

node scripts/test-client.mjs https://mcp-for-next-js.vercel.app

Cursor	❌	✅	❌	Tools Only

🛠️ Advanced Configuration & Security

For advanced users, the server allows custom configuration via environment variables and command-line arguments. Developers can adjust these settings in app/route.ts to fit specific needs.

Example configuration:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}
