Have you tried it though? There are sdks where you can set up logging and MCP server or client in a few lines. Pydantic AI and Logfire as one example





Yes, there are SDKs that abstract away some of the setup. But what exactly is being logged? Where is the data going? How tamper-proof is that logging? How is the network communication implemented? How do you check those logs? What exactly is being sent through the line? It’s hard to audit, especially without deep visibility into the underlying layers which include binary blobs and their tokens for trust. How do you model internal state? How do you write regression tests?

SDKs aren't a spec.

A spec is what I use to write an SDK.
