I love the article & the protocol. However, MCP reminded me (somewhat) of microservices & SOA. Are we creating failure vectors nightmare? Or, is it, because of agents, we can gracefully increase reliability?

I can't be the only person that non-ironically has this.

Bret Victor had an old video where he talked about a world in which computers very organically figured out how to interoperate. MCP feels like the first realization of that idea.

Yup. Makes sense. The biggest value of MCP is that everyone is using MCP. This too is not a new insight.

Omg I wish people would just shut up about mcp already.

It's not magic, it's just smashing tool descriptions into your prompt, and the implementation sucks for various reasons, including there being no standard for tool use tags, nor the mcp spec including a common way of handling function call responses.

It's literally just "json into prompt & then it's all you buddy!" batteries NOT included, lmao

Is this basically the XML/RSS/semantic web of this tech wave?
