GPT MCP Server: Universal Adapter for AI Application Integration

Overview: What is GPT MCP Server?

GPT MCP Server is a specialized MCP (Model Context Protocol) implementation that bridges OpenAI’s powerful GPT function calling capabilities with real-world backend API calls through a locally hosted server. This project allows developers to build and integrate versatile AI applications such as Claude Desktop, Continue, Cursor, and others into their ecosystems via a standardized protocol. By enabling seamless communication between AI models and external tools and data sources, GPT MCP Server enhances the functionality and flexibility of AI-driven workflows.

🔧 Core Features & MCP Capabilities

GPT MCP Server offers several key features that leverage the power of MCP for AI applications:

• Tool Calling with Real API Backend: The server allows AI models to interact with external tools and data sources through RESTful APIs, providing a clean modular structure.
• Clean Modular Architecture: A well-structured codebase ensures ease of maintenance and scalability, enabling developers to add or modify tools without disruptive changes.

🛠️ Advanced Configuration & Security

Example Configuration Code Sample

Here is an example configuration snippet that demonstrates setting up MCP clients within your server application:

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

This configuration snippet showcases how to integrate and manage MCP server instances within your project.

Security Considerations

To ensure secure connections, GPT MCP Server employs TLS/SSL encryption for data transmission. Additionally, developers can customize security settings by configuring environment variables such as API_KEY_SECRET or using an authentication mechanism like OAuth2.
