MCP is dead? | Hacker News

A Hacker News debate asked whether Model Context Protocol (MCP) is already obsolete.

An OpenAI leader behind the ChatGPT App Store, Codex plugins, and MCP said the standard still matters because companies are building MCP servers for AI agents.

Commenters argued adoption depends on user demand and that clearer REST APIs or CLIs might work just as well.

Others said MCP support in tools like Codex and Claude still feels confusing and immature.

The discussion shows how an awkward protocol can still spread if it helps services become discoverable to AI agents.
