Launching your own MCP server from scratch is easier than it seems

A step-by-step walkthrough on how to launch your own MCP server and understand the Model Context Protocol — an open standard by Anthropic that connects AI models to real-world tools through a unified protocol. The practical setup uses Docker, MCP Toolkit, and a Python server: building the image, configuring registry.yaml, and integrating everything with Cursor. The approach is fully standardized and does not require plugins or complex manual integration.
