- Praise: Having an easily detectable protocol would enhance the harness's ability to manage payment processes, ensuring deterministic code execution and improving reliability in transactions.
- Concern: The term 'protocol' seems to be overused and misapplied, leading to skepticism about the actual innovation behind MPP compared to established protocols like TCP or UDP.
- Concern: There is a lack of clarity on how MPP differentiates itself from simple API calls, raising doubts about its necessity and effectiveness in improving agent performance.
