Well OpenAPI. You don't need some wired debugging tools nobody knows how to use, a stateful protocol that is hard to troubleshoot, etc. There is plenty of support already built into standard HTTP services and Swagger - abundance of tools and documentation too and what we call function calling is basically JSON Schema which is at the core of swagger definitions.

MCP is trying to reinvent OpenAPI but in the wrong way.

doesnt seem like a good equivalent

Why not? It is easy and widely available. It has support for many development tools, from browsers to rest clients, intercepting proxies, and more.

I guess it is not exciting because nobody can put their name on it.
