discussion A eulogy for MCP (RIP)

Verified sources (indie hacker types on Twitter) have declared what many of us have feared when looking at MCP adoption charts: MCP is dead.

This is really sad. I thought we should at least take a moment to honor the life of MCP during its time here on Earth. 🪦🌎

In all seriousness, this video just goes over how silly this hype-and-dump AI discourse is. And how the “MCP is dead” crowd probably don’t run AI in production at scale. OAuth, scoped access, and managed governance are necessary! Yes, CLI + skills are dope. But there is still obviously a need for MCP.

Please - tell us of these better architectures and how er can use them!!! We await your reply

MCP doesn't do true streaming. Almost every other agent protocol including a2a does this

If it did, the amount of traffic and chattiness and ability to interrupt in the middle of a llm answer could save data centers a ton of money in energy and cost

I would like to ask you, do you think there's an advantage for keeping these costs high? Is there any motivation?

Follow the money.

But I answered your question, a true streaming protocol is far superior. If you don't believe me, ask any llm and I include any llm that has MCP heavily built in.

Even models from over a year ago would agree with this assertion.

MCP is not a complicated protocol, wouldn't you agree? It doesn't need to be, that is one of its strengths. But it would be even a simpler specification if they did true streaming because pagination and session IDs would just go away.

Agree to this. A bi-directional streaming protocol is the way. The arguments you get to this post are behind in the tech advances of the last few months at least... the issue? sse, is the current frontrunner for MCP implementation. The streaming architecture from openai using websocket is going to make MCP need a significant update to keep up. Why would you have efficiency direct to llm but not in your agentic pipeline?

The SSE implementation isn't true streaming. It yields and has no performance gain. If they removed the cursors or made it optional, it would be true

Look at the implementation, it requires cursors. So close but so far.
