A lightweight reference implementation that demonstrates MCP server patterns in Python. It exposes a single `random_float` tool that returns a random number between 0 and 1, which makes it most useful as a starting point for building your own MCP servers rather than a production integration. Supports STDIO, HTTP, and SSE transports out of the box, with Docker packaging included. The codebase is minimal and well-documented with examples for local development and Claude Desktop integration. Reach for this when you need a working template to understand MCP server architecture or want to prototype a custom tool without framework overhead.
