Anthropic were the progenitors of the Model Context Protocol. Claude Code does not fully implement the client end of the protocol. A protocol; a literal pre-defined spec that an agent should be able to one-shot. Neither does Codex. Codex does not implement MCP Prompts.

(I want Codex to implement MCP Prompts because then we have one central way to ship skills from a server).

The fact that neither platform can implement a protocol given what is functionally infinite frontier model tokens really says a lot. I do not care what kind of random project some influencer can ship with a swarm of 1000 agents. If you cannot make the basics work, it is a farce.

It still boggles my mind that Anthropic would invent the MCP protocol but not fully implement it.

Especially when fully implementing it (prompts, resources, tools) is easily done in harnesses that don’t ship with MCP but allow good extension / modification like Pi.

Claude not being able to see its own usage or self invoke slash commands is also very frustrating.
