Template Project to Build MCP Server Using SpringBoot: Universal Adapter for AI Applications

Overview: What is Template Project to Build MCP Server?

The Template Project serves as a foundational framework for developing an MCP (Model Context Protocol) server using Spring Boot technology. Built on the principles of standardization and versatility, this project is designed to enable seamless integration between AI applications like Claude Desktop, Continue, Cursor, and others with diverse data sources and tools through a universal protocol.

🔧 Core Features & MCP Capabilities

The template project is meticulously structured to expose features via REST endpoints. This allows users to test the functionalities outside of their MCP clients, providing a robust foundation for developers looking to leverage the protocol's capabilities. A prime example included within the template is the task feature, which acts as a guideline for building new tools and resources. This feature includes comprehensive unit and integration tests, ensuring reliability and robustness in deployment.

⚙️ MCP Architecture & Protocol Implementation

Implementing MCP via this project involves understanding and adhering to its protocol. The server communicates with MCP clients using the model context protocol, allowing it to interact with various application environments. By following the architecture established within the template, developers can ensure compatibility across multiple AI applications while maintaining a modular structure that is easy to extend or modify.

🚀 Getting Started with Installation

To configure an MCP client like Claude Desktop to communicate with this server, follow these steps:

1. Locate Configuration File: Open the file ~/Library/Application Support/Claude/claude_desktop_config.json.
2. Add Server Entry: Insert the following section:

   {
     "command": "/usr/bin/java",
     "args": [
       "-Dspring.profiles.active=default",
       "-Dspring.main.web-application-type=none",
       "-jar",
       "<PATH_TO_REPO>/build/libs/<your-app-name>-0.0.1-SNAPSHOT.jar"
     ]
   }
   

💡 Key Use Cases in AI Workflows

AI workflows that benefit from integration with the MCP protocol often revolve around enhancing user experience and tool efficiency across different applications. For instance, integrating a text analysis tool into Claude Desktop can streamline content evaluation processes. Another use case involves dynamically fetching data from various sources to support prompt engineering tasks without manual intervention.

🔌 Integration with MCP Clients

The template project supports multiple MCP clients, ensuring flexibility in deployment scenarios. However, it is most compatible with the following applications:

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

📊 Performance & Compatibility Matrix

To ensure optimal performance and compatibility, consider the following matrix that details how different elements integrate with the server:

• API Key Authentication: Secure access control for each MCP client.
• Customizable Endpoints: Dynamic configuration of endpoints to match diverse application needs.

🛠️ Advanced Configuration & Security

Advanced configurations within the server involve setting up environment variables and fine-tuning security settings. Developers can add custom environment variables such as API_KEY, ensuring secure API key management:

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