Oat++ MCP Server: Autogenerated API Tools and Standardized AI Application Integration

Overview: What is Oat++ MCP Server?

Oat++ MCP (Model Context Protocol) Server is an extension library for the Oat++ web framework, designed to facilitate the connection between AI applications and specific data sources or tools via a standardized protocol. By adhering to the Model Context Protocol, Oat++ MCP Server ensures that developers can seamlessly integrate their AI applications with various endpoints and resources using predefined APIs. This server is particularly useful for building robust and versatile AI workflows.

🔧 Core Features & MCP Capabilities

The Oat++ MCP Server offers several core features and capabilities, making it a powerful tool for integrating AI models with diverse data sources and tools:

1. Autogenerated API Tools: Developers can leverage oatpp-mcp to automatically generate APIs from ApiController, enabling LLMs (Language Model Languages) to query backend services.

2. Transport Protocols:

   • STDIO: A low-level protocol for debugging and local testing.
   • HTTP Server Sent Events (SSE): Used for real-time data feeds over HTTP.

3. Server-Side Features:

   • Prompts: Define specific tasks or questions that the AI model should address.
   • Resources: Specify available data sources accessible to the model.
   • Tools: Allow the model to interact with external services or internal APIs.

⚙️ MCP Architecture & Protocol Implementation

The architecture of Oat++ MCP Server is meticulously designed to align with the Model Context Protocol specifications, ensuring seamless interoperability across various AI frameworks and tools. The server handles API generation, connection management, and protocol-specific interactions using a combination of C++ and standardized interfaces.

🚀 Getting Started with Installation

To get started with the Oat++ MCP Server, you need to meet some pre-requisites and follow specific installation steps:

1. Pre-requirements:

   • Ensure that you have installed the main Oat++ module.

2. Installation:

   • Clone the repository.

   • Create a build directory, navigate to it, and run the CMake installation:

     mkdir build && cd build
     cmake ..
     make install
     

💡 Key Use Cases in AI Workflows

Oat++ MCP Server provides extensive capabilities that can be leveraged in various AI workflows. Here are two realistic use cases to illustrate its functionality:

1. Code Review Prompt:

   • Suppose you are developing a software project and want an AI model to review the codebase for potential issues.

     server.addPrompt(std::make_shared<prompts::CodeReview>());
     

   • The CodeReview prompt can be implemented as follows in the MCP server:

     /* Create MCP server */
     oatpp::mcp::Server server;
     
     /* Add prompts */
     server.addPrompt(std::make_shared<prompts::CodeReview>());
     
     /* Run server */
     server.stdioListen(); 
     

2. File Resource Management:

   • You can manage and query files stored in a data repository as resources for the AI model.

     // Add resource to server
     server.addResource(std::make_shared<resource::File>());
