# The questions I kept answering twice

These six pieces exist because the same questions kept arriving in my inbox and in issues. What MCP actually is once you strip the marketing, when stdio beats HTTP, how the memory architectures really differ, and what agent orchestration looks like when you have run it in production. Each one is written from building the thing, not from reading about it. None of them sells anything.
