Yeah even I don't understand how it exactly solves the NXM problem (which translates to having M different prompts for N different llms. corerct me if I'm wrong please)

N (LLM clients/vendors) x M (tools/tool suppliers).

The N×M problem may simply be moved rather than solved:

  - Instead of N×M direct integrations
  - We now have N MCP client implementations
  - M MCP server implementations

This feels similar to SOAP but might be more of a lower level protocol similar to HTTP itself. Hard to tell with the implementation examples being pretty subjective programs in python.
