Introduction Hi everyone, recently I’ve seen people talking about MCP (Model Context Protocol) everywhere. From AI assistants and tool-calling to extensions, MCP keeps popping up 😐. Since I’m currently learning it too, I want to share how to build your first MCP server using MCP Framework . After that, we’ll test it with MCP Inspector , then finally add it to an MCP host — in this case, Copilot.
