Sesame, salt, and substance. A flagship bake.
Summary
fastmcpp is a high-performance C++ implementation of the Model Context Protocol (MCP), ported from the Python fastmcp library. It provides native performance for MCP servers and clients with support for tools, resources, prompts, and multiple transport layers including STDIO, HTTP/SSE, and Streamable HTTP. The project is currently in beta with version 2.15.0 and implements core MCP protocol features including JSON-RPC, tool management, and session management for Streamable HTTP transport.
