The MCP is the deterministic program.

You need to take a step back and look at the problem you're discussing. What's exactly this MCP thing? It's a protocol to allow agents and coding assistants to access tools, services, and data sources, through a standardized interface.

It's the interface for your deterministic program. That's it.
