MCP Is Not Good Yet — David Cramer, Sentry

David Cramer

Overview

David Cramer of Sentry discusses the current state of MCP (Model Communication Protocol), framing it as a pluggable architecture for agents. He emphasizes that while the concept is powerful, current implementations are often rough and require significant design effort. Cramer suggests that MCP's true value lies in its ability to integrate services into agent workflows, particularly for B2B SaaS companies, by providing context that LLMs can reason about.

Notable quotes

MCP is a pluggable architecture for agents. Full stop. That's it.
*MCP is not a thing that just sits on top of Open API. Like you cannot just be like I got an API. I'm going to expose all those end points as tools. You're going to get the worst results you can possibly imagine.*
*The fancy new words are just new words for the same thing. It's just a new like code of paint, right? You know MCP is just a plugin architecture.*
