the problem of agents is not the lack of standards, but reliability (reliability of tool use and reliability of outcomes). MCP does not solve any of that.
Standards might not have been _the_ problem, but they were _a_ problem. Before MCP I couldn't distribute a tool call that could be configured by end-users to be used with multiple mainstream clients.
This is just moving the goalposts, MCP is not supposed to solve every problem with agents. It's meant to make it easier to provide easier, standardised ways for LLMs to interact with external tools, which it has done. Reliability is a completely different problem.
