Summary
This is the kitchen sink reference implementation for the mctx framework. It demonstrates every MCP pattern in one annotated file: sync and async tools, progress notifications, LLM sampling via `res.ask`, user identity through `mctx.userId`, static and templated resources, single and multi-message prompts. Includes examples like a configurable greeter, calculator with validation, progress-emitting analyzer, and dynamic user profiles. Designed as a learning resource and GitHub template. The setup script lets you keep all examples for study or strip down to a minimal skeleton. Ships with comprehensive tests and a release pipeline that builds to a separate branch for mctx deployment.
