nativeMCP MCP Server

What is nativeMCP?

nativeMCP is a C++ implementation of the Model Context Protocol (MCP) system, providing a host (CLI-based AI Agent), MCP client, and MCP server framework. It is designed for developers who want to integrate MCP tools with local LLMs (via Ollama) or use MCP servers with other MCP-compatible software like Cursor.

How to use nativeMCP?

Install dependencies (Qt 6.8, cpp-httplib, Ollama), build the project with CMake and Visual Studio 2022, edit config.json to set the Ollama API URL, model, and MCP server definitions, then run the host executable. The host connects to the LLM and automatically calls MCP tools based on the user's natural‑language requests.

Key features of nativeMCP

• C++ implementation of MCP host, client, and server.
• Host acts as an AI Agent with a CLI interface.
• Server base class (MCPServer) for easy tool extension.
• Supports MCP stdio transport only.
• Integrates with Ollama for local LLM inference (e.g., deepseek, qwen).
• Compatible with MCP‑aware applications like Cursor for its servers.

Use cases of nativeMCP

• Build a local AI assistant that can call custom tools (e.g., time, network utilities).
• Develop and test MCP servers written in C++.
• Use nativeMCP servers as tools in external MCP clients (Cursor, etc.).
• Automate multi‑step tasks that combine LLM reasoning with tool execution.
