Building the Hugging Face MCP Server
Hugging Face built an MCP (Model Context Protocol) server to connect AI assistants to their Hub platform. They chose Streamable HTTP transport with stateless, direct response configuration for production deployment. The server provides customizable tools for accessing thousands of AI applications and supports multiple transport options including STDIO, HTTP with SSE, and Streamable HTTP. Key design decisions focused on simplicity, scalability, and avoiding complex state management while supporting both anonymous and authenticated users.
