Oatpp MCP Server
Implement the Model Context Protocol directly within your C++ Oat++ web services.
Data last scanned today · Reviewed today
Overview
Oatpp MCP Server provides a C++ framework for integrating the Model Context Protocol into applications built with the Oat++ library. It enables developers to expose their API controllers as LLM-accessible tools, facilitating direct communication between your C++ services and AI agents. The implementation supports communication via STDIO and HTTP SSE transports. Developers can register custom prompts, resources, and tools within their existing Oat++ environment to extend AI capabilities to their backend logic.
